Importing Your Code Signing Assets from Your File System
In the Devices organizer, select your team in the Teams section.
Select the file containing your code signing assets.
Enter the password for the file, and click Open.
Place your code signing assets on a new Mac by importing the code signing assets exported from another Mac.
The importation process installs the certificates, private keys, and provisioning profiles that are stored in the developer-profile file.
