Yes. The most failsafe procedure would be:Hey guys I have my own question if I clone my MacBook Pro harddrive with Mavericks can I use the patch to patch it up so my Mac Pro 2.1 could put the cloned harddrive?
1. Open iTunes and deauthorize your current computer. Close iTunes.
2. Clone your HD using CCC, SuperDuper or similar.
3. After the clone has been made, replace the boot.efi files on the clone.
4. Boot up the Mac Pro with the clone, re-authorize iTunes in the MacBook.
5. Authorize your Mac Pro in iTunes, set up iCloud/iMessages.
6. Apply 10.9.1 to the Mac Pro (does not matter if it is already running 10.9.1 or not. Apply it again if unsure).
7. (on the Mac Pro) run the Disk Utility, fix permissions.
