Apple released Mac OS X 10.8.1, the first major update to OS X Mountain Lion. At 24 megabytes, this is a much smaller point update than usual, and does not contain any of the normal audio and graphics driver updates. To eliminate any potential issues, we generally recommend to update any supported systems using the standalone installer available from Apple.com, and not the built-in Software Update.

Be sure to back up any important data, and if possible clone your hard drive before applying the update. If you have any issues post-update, boot using UniBeast.


What we know about 10.8.1 so far...


  • 12.1.0 Darwin kernel
  • Battery drivers updated for Mac Laptops
  • USB drivers updated
  • Thunderbolt drivers updated


The Mac App Store version of 10.8.1 is now out as well, so if you'd like to update the installer drive, you can slipstream this update into UniBeast. Good luck, and let us know how it goes! Report your results here.
