"Valid signing identity not found" on New Computer - ios

I got new computer. Firstly i copied iOS-project from old one. Then, i refreshed profiles in organizer, but all of them got status "valid signing identity not found"
So in Keychain Access all certificates are OK
Any ideas? How should i valid all this profiles? Thnx

There is no private keys in your certificate
Go to your old mac click on 3 right click on private key and export that key give a password for the key. copy that to private key to pendrive and import that to new Mac Keychain it asks for Password so give the password you set in old mac when Exporting. Restart the xcode it works fine

The certificates are okay, but the private keys required to sign the certificate are not here : you can see this because there is no disclose triangle near the certificate in the Keychain.app.
The keys that goes along the certificate should have a .p12 extension, but if you can't find it, your best bet is to revoke the certificates using the DevCenter, and create them back again and download them onto that new system.

If you have your private keys in your old mac you can create your .p12 file like this:

But if you do not, you have to revoke your old certificate and create a new one.
This is such a pain sometimes. Recently I had to face this. The certificates may appear but you do not have the private keys with you. For a complete guide click below:

Export push notification certificate as P12

Normally, I can export the certificate from the keychain that I download from the apple member center as a p12 file. However, it seems that Apple may have changed something?!
I require it as a p12 to import it into Amazon's SNS service. I have tried converting to PEM files but it's producing an error on the console.
The solution I have found has been posted here: https://stackoverflow.com/a/19502944/1198404
I copy and paste the answer: Turns out all you have to do is select "My Certificates" on the left panel and it enables the .p12 option.
You can't export to a .p12 because you don't have the private key installed on your machine (if you did, you would have an "expand" arrow next to the certificate like your iPhone Distribution certificate has.) You will need to get the private key from the machine that generated the certificate before you export.
If the accepted answer doesn't apply to you (e.g., because you created the CSR from the same Mac, and should have the private key on this Mac), here's one more possibility:
When you happen to have selected the wrong keychain (like if you accidentally had single clicked on the System keychain rather than Login keychain), you may run into the same problem. If the cert signing request came from that machine, it would associate the private key with the Login keychain (at least, that seems to be the default). So if you somehow then downloaded and imported the certificate into another keychain like the System keychain (or iCloud keychain, as some comments have mentioned), Keychain Access would not find the matching private key and would not put the cert under "My certificates", and so it cannot export a p12. It would be similar to the case of importing to the keychain on a different Mac.
Make sure the import is into the keychain associated with the private key. Often this would be the Login keychain.
You don't have the private key.
So the solution is you have to revoke the previous certificate and create a new APNS profile again.
You can export from Cert just like below.

certificate selected by provision profile is incorrect

I have created certificate & provisioning profile related to my iphone app.
but when I run app it shows doesn't match any valid certificate/private key pair in the default keychain
& then I realize that it is not certificate which i have created.
what should I do now?
I have tried to delete previous certificate but it does also not working it again came back.
You should have the private key used to create the certificate present in your keychain app for you to be able to code sign your app. Start fresh, create a new certificate, this time make sure to store the private key as .p12 file.
You have not installed the .p12 file. Please go through the Apple docs for Certificate/Provisioning-profile creation process. That will help you to understand the whole process of signing an iOS app.
You can always verify certificate, which provision created with.
Provision profile have public key encoded in base64. You can compare hash sums or finger print with private key on your mac.
Here is example code how to export certificate from provision in ruby gist.gitgub

missing private key in the distribution certificate on keychain

I have the following problem which I could not find a solution for anywhere. Basically, we have a company developer account (not enterprise) and so in order to submit our app, I requested from our team lead to send me the distribution certificate and create and send me a distribution provisioning profile.
With the developer profile, everything works good, but when I installed the cert and the provisioning profile, I did not see the distribution profile on Xcode, and nor do I have a private key under the dist cert in the keychain.
Does anyone know how to solve this? I read in diff places that I will need to revoke the certificate and create a new one, but I can't really do that since we have a bunch of apps in the company and I can't revoke it for everyone.
Ahh this is a common issue, The solution is simple:
Who ever created the developer credentials originally needs to go to the keychain on their computer and right click on the key(s) for private and public and export the key to a file.
Then you just download that file on your computer and open it, and it will be added to your keychain.
You need to have both the private key (.pem file) and the certificate for your provisioning profiles.
As long as you still have access to the mac which was used to generate the original distribution certificate it's very simple.
Just use that mac's Keychain Access application to export both the certificate and the private key. Select both using shift or command and right click to export to a .p12 file.
Attached a screenshot to make it very clear.
On your mac, import that .p12 file and you are good to go (just make sure you have a valid provisioning profile).
To add on to others' answers, if you don't have access to that private key anymore it's fairly simple to get back up and running:
revoke your active certificate in the provisioning portal
create new developer certificate (keychain access/.../request for csr...etc.)
download and install a new certificate
create a new provisioning profile for existing app id (on provisioning portal)
download and install new provisioning profile and in the build, settings set the appropriate code signing identities
Delete the existing one from KeyChain, get and add the .p12 file to your mac from where the certificate was created.
To get .p12 from source Mac, go to KeyChain, expand the certificate, select both and export 2 items. This will save .p12 file in your location:
For person who are afraid on re-creating AppStore distribution certificate Apple documentation says:
Important: Re-creating your development or distribution certificates
doesn’t affect apps that you’ve submitted to the App Store nor does it
affect your ability to update them.
But it affects apps for Apple Developer Enterprise ecosystem.
I lost hours and hours to resolve this issue, but it's fixed by just restarting MAC...
In my case, I've lost all private keys in my keychain, new ones were imported correctly, but doesn't show the private key as well. The only thing that helped was generating new CertificateSigningRequest
After you changed a Mac which are not the origin one who created the disitribution certificate, you will missing the private key.Just delete the origin certificate and recreate a new one, that works for me~
When I try to upload iOS build to test flight then error was appear.
"Missing privacy key".
Just 2 step for fix this error.
Remove old certificate from developer.apple.com
Create new certificate from Xcode or developer.apple.com
My problem has been solved (I am using Xcode 9.4.1).
Please check, Xcode created new certificate.
If you are creating your own Distribution cert, not using someone else's then this could help.
Spent quite a bit of time on this today, issues from not being able to create a SigningRequest to generating a distribution cert and not having it attached to my private key in KeyChain Access. These steps helped solve this for me.
If you are still having issues, revoke your current cert and start fresh.
Creating a new signing request
The Keychain Access > Certificate Assistant > Request a Certificate from a Certificate Authority is actually contextually aware of what you currently have selected when you launch it. Just to be sure that you aren't accidentally skewing your Request with some random selection, go to your Login Items and select the Apple Worldwide Developer item. Then launch the above Request and create the CertificateSigningRequest.certSigningRequest file.
Go to Apple Dev portal, add new distribution certificate, upload your CertificateSigningRequest.certSigningRequest file and download the newly created distribution certificate.
To import the distribution cert into your keychain, instead of just double clicking it, I recommend opening your keychain, go to "login/Certificates" area and drag and drop the cert here.
I had an issue where my cert would auto-install into the System area, instead of the login area where my private key existed and this caused my key not to be linked to the new cert.
At the Menu > Visual Studio (mac) > Preferences > Publishing > Apple Developer Accounts > [Select your apple id] > View Details > Create Certificate
To delete unused/invalid certificates, go to website: https://developer.apple.com/account/resources/certificates/list
delete any unwanted certificate there
Next is to create App ID (identifiers), go to website:
https://developer.apple.com/account/resources/identifiers/list
Next, go to website to create provisioning profiles:
https://developer.apple.com/account/resources/profiles/add
use the certificate to bind with your app id.
Next is to download the profiles:
At your mac > At the Menu > Visual Studio (mac) > Preferences > Publishing > Apple Developer Accounts > [Select your apple id] > View Details > Download All Profiles
I got into this situation ("Missing private key.") after Xcode failed to create new distribution certificate - an unknown error occurred.
Then, I struggled to obtain the private key or to generate new certificate. From the certificate manager in Xcode I got strange errors like "The passphrase you entered is wrong". But it did not even ask me for any passphrase.
What helped me was:
Revoke all not-working distribution certificates at developer.apple.com
Restart my Mac
After that, Xcode was able to create new distribution certificate and no private key was missing.
Lesson learned: Restart your Mac as much as your Windows ;)
I accessed that certificate on apple's developer website and after downloaded it I opened it. Likewise, at open I got a little window asking if I wanted to add the certificate to keychain. Just tapped "add" and the "missing private key" error was gone.
My problem was that for whatever reason, the login keychain was missing in the Keychain Access. Xcode created a new certificate and added it to the login keychain but could not use it. Restarting the computer solved my problem.
Just to shed some light on this.
After I deleted my p12 certificate from Keychain. I re-downloaded my own certificate from Apple developer portal.
I was only able to download the certificate. But to sign you need the private key as well. So you either:
export both private key and certificate from Keychain to get it.
Upload a Certificate Signing Request and generate new certificates
That certificate by itself has no value for signing purposes. My guess is that the private key is created by keychain the moment you 'request a certificate from a certificate authority' but isn't shown to you until you add its matching certificate.
Check whether you are using Login or not to add the certificates, if you are checking in System at top left hand side then we wont be able to see it.
So drag and drop the .cer into login then check you are able to get the private key or not.
I'm the creator of the key, but the key was attached to an expired Certificate.
To solve it I went to -> Xcode/Preferences/Accounts/"Account you use to archive"/Manage Certificates..
Then click on the dropdown menu with the "+" sign on the bottom left corner, and choose the type of certificate you need updated (mine was Apple Distribution).
This updated my new certificate with its key attached.
Contact with the creator of iOS Distribution key and tell to export certificate and private key, then just download and double click it to access in your keychain.
I assume you have switched device and trying to create a new certificate for your new device,
First revive the development certificate form the developers portal,
Go to xcode > preferences > accounts > select your apple id with the dev portal access > manage certificates > click on the team account > click on the little + button > click on apple distribution
Go to the apple developer portal , you can see a distribution certificate is created ,
Go to profiles create a new profile with the new certificate.
Download > install
done
An old XCode version will also cause this. I was on XCode10 (old for 2022). Updated to latest version, which resolved the issue.
I could resolve this problem by updating macOS and XCode.

iOS and XCode: Issue with certificates

I've search the web but couldn't find a solution exactly for my problem. I've created a Development Provisioning Profiles in iOS Provisioning Portal and added it to my iMac. I can successfully deploy applications to my iPhone.
Now I'm trying to deploy the same application from my MacBook Pro. I've installed the profile but gets an error:
XCode could not find a valid private certificate/valid key-pair for this profile in your keychain
I think that I need a private key from my iMac which I have to import to my MacBook Pro. Right? My question is, where can I find that private key?
When you have generated your certificate, Apple requires you to use Keychain Access for generating a certificate signing request (CSR). When you've done this, a private key has been generated in your keychain.
You got the error above because you don't have transfered this private key between your Macs.
Here is the guide to do so (the link is for mac, but it's the same manipulation). From your iMac :
Open Keychain Access in the /Applications/Utilities folder.
Select the signing certificates you want to export.
Choose File > Export items.
Choose Personal Information Exchange (.p12) as the file format and click Save.
Enter a password and click OK when done.
Transfer the p12 on your macbook, and :
Double-click the exported file that has a .p12 extension.
Extracted from :
http://developer.apple.com/library/mac/#documentation/ToolsLanguages/Conceptual/OSXWorkflowGuide/CodeSigning/CodeSigning.html#//apple_ref/doc/uid/TP40011201-CH7-SW17
Revoke the current certificate then follow the prompts regarding keychain Access when you go create new and then you should be fine.
You can still use your keychain to create the CSR, and then upload it on the new provisioning portal. Just did it the other day.

iPhone app signing: A valid signing identity matching this profile could not be found in your keychain

I'm pulling my hair out over this. I just downloaded the iPhone 3.0 SDK, but now I can't get my provisioning profiles to work. Here is what I have tried:
Delete all provisioning profiles
Delete login keychain
Create new "login" keychain, make it
default
Create a new certificate signing request
Create new developer and distribution
certificates in the Apple developer center
Download and install them
Download the WWDR certificate and install it
Create a new provisioning profile and
double click it to install
All the certificates report as valid, but Xcode still won't recognize them. What should I try next?
Edit:
I completely re-installed Mac OS X and from a fresh install installed the 3.0 SDK and still have the same problem.
I had the same problem: I first downloaded my certificates to my small MacBook while on the run. When trying to install the certificates on my iMac... then I ran into the problems described on this page.
After spending hours pulling my hair out like many of you, I performed the following steps to fix it:
Close all your stuff except your webpage that should be logged into App Dev center.
Open Xcode. Click WINDOW > ORGANIZER. Then click the Devices tab and select "Provisioning Profiles" on the left.
That should bring up your provisioning profiles. Highlight one by one (if more than 1), right click and delete profile. Yes, just do it! Delete them all! (I kept making a new one after a new one trying to make the thing work.)
From the first page you see after logging into the App Dev Center on the right side click "iOS PROVISIONING PORTAL" > (do not "launch assistant"). Instead click on the left side. Select CERTIFICATES. You will probably have just one line listed with your name/company - from there click on the right side REVOKE. Click OK to verify that's what you want to do.
On the same page click DEVICES. Click the box next to your device you are trying to provision and click REMOVE SELECTED. Again click OK to verify.
Wait about 2 minutes to let Apple do their thing.
Now click on "HOME" that is on the left side navigation.
Click "Launch Assistant"
create a new app ID - call it whatever you want. Just make sure it's unique enough to know that's the one you just created because the others you've been messing with all day will not be deleted from Apples Dev Center.
You should be able to follow the rest of the Assistant without troubles -- the main thing is you just had to delete your old provision profiles and start over.
Good Luck!
I encountered the same issue. This is because the private key of the certificate does not existing on your machine.
If you are now using a new machine and download the certificate from website:
You can export the certificate from the old machine and then import on the new machine.
If you share the developer account with someone:
You ask the account owner to send you an invitation and become a team member of that account. Then you can create your own certificate from scratch.
If you don't want to handle all these sh*t:
Just revoke the certificate on website and delete the copy on your local machine. Then request a new one. This should be the ultimate way for solving such issue.
Had the same problem yesterday. Now, after signing to the developer portal, for every invalid provisioning profile have a button "Renew". After renewing and downloading updated provisioning profile all seems to work as expected, so problem is definitely solved :)
Update: you may have to contact Apple to get a "Renew"-button, or they removed it -- and the solution is to just download it and add it to the keychain, no need to renew.
What I found was that I needed to drag the distribution_identity.cer file that I downloaded from the "Certificates -> Distribution" page on the developer program portal into the keychain access program, then this error went away.
I solved it by
a) go to provisioning profile page on the portal
b) Click on Edit on the provisioning profile you are having trouble (right hand side).
c) Check the Appropriate Certificate box (not checked by default) and select the correct App ID (my old one was expired)
d) Download and use the new provisioning profile. Delete the old one(s).
Apparently there are 4 different causes of this problem:
Your Keychain is missing the private key associated with your
iPhone Developer or iPhone
Distribution certificate.
Your Keychain is missing the Apple Worldwide Developer Relations
Intermediate Certificate.
Your certificate was revoked or has expired.
Online Certificate Status Protocol (OCSP) or Certificate
Revocation List (CRL) are turned on in
Keychain Access preferences
.
After carefully going through the thread here and checking all the solutions proposed by people, I can confidently claim this, after following the steps mentioned on Apple developer docs for creating CSR and mobile provision file, just do this!,
Launch Xcode.
Select window->Organizer
Click this refresh button and that filthy yellow bar will remove instantly.
http://img.skitch.com/20100820-1ngm8an14c6fm3dt7g6j51d2nx.jpg
Trust me, you only have to do this. There is no need to repeat the process again and again to make sure that you doing it the right way. Just press Refresh, enter your login credentials and it's done.
For me it only worked when the certificate and both keys were in the Login keychain. I had created a Development keychain before, but the Xcode Organizer wouldn't find the keys in there. So I moved them back to Login, quit the keychain tool - and voila, the error in Xcode Organizer went away! This was on Snow Leopard 10.6.2 with the 3.1.3 SDK.
For development certificates you can just create a new one and match it to a profile. However for distribution, like when your going to submit to Apple, you cannot do this and must use the distribution certificate the team agent created. The problem is you need the private key on your machine. It's very simple, however, for the team agent who created the certificate to copy the private key to you, below are the instructions from Apple, I hope this helps.
It is critical that you save your private key somewhere safe in the event that you need to develop on multiple computers or decide to reinstall your system OS. Without your private key, you will be unable to sign binaries in Xcode and test your application on any Apple device. When a CSR is generated, the Keychain Access application creates a private key on your login keychain. This private key is tied to your user account and cannot be reproduced if lost due to an OS reinstall. If you plan to do development and testing on multiple systems, you will need to import your private key onto all of the systems you’ll be doing work on.
To export your private key and certificate for safe-keeping and for enabling development on multiple systems, open up the Keychain Access Application and select the ‘Keys’ category.
Control-Click on the private key associated with your iPhone Development Certificate and click ‘Export Items’ in the menu. The private key is identified by the iPhone Developer: public certificate that is paired with it.
Save your key in the Personal Information Exchange (.p12) file format.
You will be prompted to create a password which is used when you attempt to import this key on another computer.
You can now transfer this .p12 file between systems. Double-click on the .p12 to install it on a system. You will be prompted for the password you entered in Step 4.
The best answer I got was exporting your key, instead of just trying to import the cert file.
When you export the key from the keychain that generated the request, you get a Certificates.p12 file, which rolls the keys you need together.
Then import this into the new computer.
With keys like this, it's probably good to keep a rolled, certificate package file, because many times the "public" key, or cert file, is not enough to restore things from.
In my case, I copied the project from my iMac to my Macbook Pro and found out I didn't have my private key installed on the Macbook. So I exported my private key, copied and installed it to the Macbook, and voila it works! I've documented the information here:
http://www.creatistblog.com/2009/09/iphone-developer-provisioning.html
Just a note with Xcode 4: in the organizer there are two different sections in the left pane:
Library > Provisioning profiles
Devices > your device > Provisioning profiles
I was always puttings my provisioning profiles into 2. and even after cleaning and installing properly it was not working. Then I discovered 1. and finally I found the refresh button. If you select 'Automatic device provisioning' in 1. and click on refresh, then everything got validated (no yellow warning in 2. anymore).
Was facing a similar issue yesterday with our CI server. The app extension could not be signed with the error
Code Sign error: No matching provisioning profiles found: No provisioning profiles with a valid signing identity (i.e. certificate and private key pair) matching the bundle identifier XXX were found.
Note: I had created my provisioning profiles myself from Developer portal (not managed by Xcode).
The error was that I had created the provisioning profiles using the Distribution certificate, but the build settings were set to use the developer certificate. Changing it to use Distribution certificate solved the issue.
Summary: Match the certificate used for creating the provisioning profile in build settings too.
Did you try rebooting your Mac and your device? Lame answer, but I always try that first.
I got it working after re-doing everything and then creating an empty project with XCode and building/running it to the device. XCode showed a window asking something like: Do you want to accept the developer certificate. I pressed "Always". Only after this step I got rid of the message "A valid signing identity matching this profile could not be found in your keychain" in Organizer.
Hey guys, I had heaps of trouble with this yesterday. I went through the whole process a few times, requesting a new certificate request from the authority with the assistant, clearing out everything in the portal, uploading the certificate, creating a new profile and downloading everything. No dice.
However, check this out.
First up clear out all the certificates on the portal to start fresh.
After creating the new certificate request with the assistant, press "Show in Finder", and double click that bad boy. You should get a popup for the Certificate Assistant with a screen showing "Please specify the issuing Certificate Authority", etc. If you don't, just close it and double click again.
Now just proceed through the dialog choosing
"Request a certificate from an existing CA" - Continue
Request is "Saved to disk" - Continue
Save it where ever you like, even override the file.
At the end you should see the magic "Creating key pair"
Run over to the KeyChain access and you'll see your keys in there! Upload this certificate to the apple portal and then go through their wizard as normal, everything should work great now.
There are two different certificates for two different provisioning profiles (development and distribution). You have to install BOTH certificates in keychain. In the iPhone Developer Program Portal:
Certificates -> Development -> Download
Certificates -> Distribution -> Download
Double click both certificates. After that both certificates must appear in Keychain.
The answer is this revoke your Current Development Certificate and make a new one. follow the instructions on apples site on how to do so. Its that simple!! I had this exact problem.
Simple steps to get this done:
Start from keychain (which contains your dev key already) on your computer and create a request for certificate. Upload the request to dev site and create the certificate.
Create a profile using the certificate.
Download the profile and drop it on Xcode.
Now all the dots are connected and it should work. This works for both dev and distribution.
I logged into developer account and revoked the development certificate. After revoking and downloading the development certificate i double clicked the newly downloaded certificate and this time Private Key was there under development certificate in KeyChain Access.
A good way to ensure that this happens cleanly is to clean your login keychain completely first.
Also, a really important step is to unlock your keychain before you import the private key and public key
security unlock-keychain -p password ~/Library/Keychains/login.keychain
Import private key into login keychain :
security import PrivateKey.p12 -k ~/Library/Keychains/login.keychain
1 identity imported.
Import public key into login keychain :
security import PublicKeyName.pem -k ~/Library/Keychains/login.keychain
1 key imported.
I had this same problem but, it was due to my setting up "FileVault" on my Mac. I went into my keychain and set "login" to be my default and that fixed it.
"This was a bug on the Apple portal site. They were missing a necessary field in the provisioning profile. They fixed this bug late on 6/16/09. "
I don't know whether they really skipped it or if my eyes were just glazing over but....
Just in case anybody else is overlooking the same things that I did....
just as when you were developing and testing...
1) You need a DISTRIBUTION << CERTIFICATE >>
2) You need a DISTRIBUTION << PROVISIONING PROFILE >>
That is TWO STEPS on the portal in order to get the thing signed.
There I was, having created the developer CERTIFICATE and copied it to the Mobile Provisions folder, wondering why it didn't work.
As soon as I had the provisioning profile in place
* BINGO *
I had the exact same problem and tried everything. For whatever reason the solution was that all my certificates had migrated to a keychain called "microsoft_intermediate_certificates". As it probably happened during an Xcode upgrade I have absolutely no idea why, but it may help somebody.
I moved all content of the Microsoft keychain to the login keychain and everything went back to normal.
I finally got this to work after, like, 4 separate tries after incurring the same problem that was originally posted. So here's what happened, I am not sure if this is an old issue now (2009-07-09), but I will post anyway in case it is helpful to you. What worked for me... might work for you...
start anew and delete the old private keys, public keys, and certificates in the keychain
go through the whole process, request a certificate from a certificate authority, get a new public key, a new private key, and a new certificate. Note: when it worked I had exactly one private key, one public key, and one certificate
Make a new provisioning profile (which utilizes the certificate that you just made) and put that in your organizer window in Xcode. Delete all the old BS.
Run it.
Hopefully this helps.
Everyone here is very wrong. All you need is to follow the steps that Apple provides in Managing Your Digital Identities.
It instructs you to export your certificates through Xcode and reimport through Xcode. It works great, but make sure your username is the same on both computers or it will fail.
I just spent several hours on this fershlugginer issue, which cropped up after renewing my development license. To reiterate, everything was working without a hitch, then (thank you Apple!) it all got screwed up and stayed screwed up. None of the Apple official troubleshooting steps (linked to above) or possible resolution steps mentioned here resolved the issue for me.
What finally did it for me was to delete both my development and distribution certificates, revoke them in the provisioning portal, and then let Xcode AUTOMATICALLY refresh/issue them. Nothing else, in any order, was able to get both required certificates into my keychain with the private key correctly attached.
Here is what I did.
Make sure your certificates have not expired, make sure you delete all the expired ones. Get new ones etc, Once you have make sure all that is the way it should be, then focus on your project files.
in finder , go to your .xcodeproj files then show package contentes.
open project.pbxproj in xcode or textedit.
find every refrense to PROVISIONING_PROFILE and remove the GUID, just leave empty ""
Depending on your project you should have about 12+ refrences, remove all of the GUIDS.
Save file, then reopen your project in XCODE
Re select the correct provision profiles for all possible code signings( they should not all be the same)
Build your project and you should be good to go.
I think Xcode gets confused some how, and removing all the Provision Profiles from the project.pbxproj and then reselecting a valid profile will set it striaght.
If you have new mac you can go to
IOS developer center --> Provisioning Portal --> Certificates --> Development --> Revoke and create new certificate. My problem solved. My error is "Code Sign error: The identity 'iPhone Developer' doesn't match any valid, non-expired certificate/private key pair in your keychains"
What you need:
1) A private and a public key.
They have this symbol in your keychain:
2) A certificate made from the signing request of those keys
3) A provisioning profile linked to that certificate
Let's say you change computers and want to set up Xcode with provisioning profiles again. How do you do it?
Open Xcode, press ctrl + O to open the Organizer, and delete all provisioning profiles you might have installed already.
Open keychain access, and create a signing request which you save to file (when you create the request, a private and public key is created in your keychain).
Create/Update a certificate in the provisioning portal by sending apple this signing request
Download and install the newly created certificate.
Revoke your provisioning profiles and update them with the new certificate.
Download and install the newly updated provisioning profiles.
