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
