I have been trying to upgrade a 13" Retina MBP to 10.8.2 by cloning the system from another disk (using CCC).

The result is that I no longer have a 10.8.1 recovery partition on the 13 retina, so it won't boot.


I guess I have to find the complete 10.8.1 dmg file, which I'm not finding anywhere.

Is there a way to find at least the recovery partition for 10.8.1 ?



MacBook Pro with Retina display, OS X Mountain Lion (10.8.2)

There is no disk image, DVD, or a download unless you purchase a copy at the App Store. You should hopefully learn to ask first, shoot later.


OS X (Lion/Mountain Lion)- About OS X Recovery.


When you manage to reinstall 10.8.1 you can then install the OS X Mountain Lion Update v10.8.2 (Combo) followed by the new OS X Mountain Lion 10.8.2 Supplemental Update 2.0 released yesterday specifically for the 13" Retina MBP.


If you plan to clone Lion or Mountain Lion volumes together with their Recovey HDs, then use Disk Utility's Restore option to do the job. CCC can clone a Recovery HD but only if one already exists on the Source drive.

It's my understanding that you have to install the Combo updater first. The Supplemental updater info says that 10.8.2 is required.


Sure, it can be done using TDM via Thunderbolt.
