Question

I had a Macintosh I used to develop iPhone apps with using Xcode 4.
I now have a new Macintosh with a new install of… everything.

When opening Xcode projects built on the old Mac, I cannot run the app on the iPhone that was configured as a development iPhone.
Xcode 4 organizer tells me "Valid signing identity not found" on my provisioning profiles.

I guess this is something to do with the .certSigningRequest file I had generated before on the old Mac (I have a backup of that file), but what do I have to do with it on the new Mac?

Another strange thing, I don’t see my 5 existing provisioning profiles (defined on Apple provisioning portal) in the organizer, even after a refresh and after having entered my provisioning portal login and password :

With Xcode 4.2 and later versions, including Xcode 4.6, there is a better way to migrate your entire developer profile to a new machine. On your existing machine, launch Xcode and do this:

1. Open the Organizer (Shift-Command-2).
2. Select the Devices tab.
3. Choose Developer Profile in the upper-left corner under LIBRARY, which may be under the heading library or under a heading called TEAMS.
4. Choose Export near the bottom left side of
   the window. Xcode asks you to choose a file name and password.

Edit for Xcode 4.4:

With Xcode 4.4, at step 3 choose Provisioning Profiles under LIBRARY. Then select your provisioning profiles either with the mouse or Command-A.

Also, Apple is making improvements in the way they manage this aspect of Xcode, and some users have reported that the Refresh button in the lower-right corner does the trick. So try clicking Refresh first, and if that doesn’t help, do the export/import sequence.

Edit for Xcode 5.0 or newer:

1. Open Xcode -> Preferences (‘Command’ + ‘,’)
2. Select the Apple ID from the list.
3. Click on the SETTING icon near the bottom-left corner of window, and choose EXPORT ACCOUNTS… Xcode asks you to choose a file name and password.

On your new machine, launch Xcode and import the profile you exported above. Works like a charm.
