Trouble with ProKit 6.0.1 Update? Restore a Previous Version

There are reports of some people having issues with the recent ProKit 6.0.1 update, but Apple have been quiet on the matter.

If you’re one of the people and you’ve tried the various fixes that can be found, but you’ll still having issues, then this is what worked for me:

  1. Download ProKit 5.1 from Apple.
  2. Double-click ProKitUpdate5.1.dmg and you’ll see ProKitUpdate5.1.mpkg.
  3. Right-click (or Ctrl-click) ProKitUpdate5.1.mpkg and click Show Package Contents.
  4. Expand Contents and Packages revealing ProAppRuntime.pkg and ProRuntime.pkg.
  5. Right-click (or Ctrl-click) ProAppRuntime.pkg and click Show Package Contents.
  6. Expand Contents and copy Archive.pax.gz to your Desktop.
  7. Double-click Archive.pax.gz and the Archive Utility will extract the contents to a folder called Archive.
  8. Within the Archive folder, navigate to System/Library/PrivateFrameworks and copy the ProKit.framework folder to your Desktop.
  9. You now have version 5.1 of the ProKit.framework ready to replace the 6.0.1 version.

  10. Open up Terminal (which can be found in /Applications/Utilities) and enter the following command:
  11. sudo pkgutil --forget com.apple.pkg.ProAppRuntime

    Since you’re running the command through the Super User account, you’ll be prompted for your Administrator password. Type in your password and click OK.

  12. In Finder, navigate to /System/Library/PrivateFrameworks and copy the ProKit.framework folder to your Documents folder.
  13. Delete the ProKit.framework folder from /System/Library/PrivateFrameworks. You’ll be prompted for your Administrator password.
  14. This is important. I’ve seen users inadvertently copy ProKit.framework 5.1 into the existing ProKit.framework folder. Deleting the existing ProKit.framework folder will ensue this does not happen.
  15. Copy the ProKit.framework folder from your Desktop to /System/Library/PrivateFrameworks. You’ll be prompted for your Administrator password again.
  16. Launch Final Cut Studio and you should be good to go.
