![]() ![]() ![]() Reinstalling Lion/Mountain Lion Without Erasing the Driveīoot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. From there, copy the original preference files back into the /Library/Preferences/ folder of the drive you're testing.How do you do that "accidentally" when the OS won't even allow you to delete it without entering your password? It the Mac does balk at the removal of these preference files, then you restart and boot to the other partition. However, that's what the other bootable drive is for. It should rebuild anything that's missing at default settings. Since they are preferences, and not critical system files, the Mac shouldn't have any trouble restarting. In this case, better to move them (or copy then delete the originals) to the other bootable drive so permission issues don't prevent you from getting at them when starting up to the other partition.

The desktop will have the default background the Dock will be at the defaults, as will pretty much everything else. The user account will come up as if it were a new account. Immediately restart the Mac after the move is complete. You will likely have to supply the admin password to complete the move. Open the user account Preferences folder and move all items to the new folder on the desktop so the Preferences folder is empty. ![]() If removed, you may need to supply that info again when you launch certain apps.īut if you want to give it a try, close any apps that are running.
