A flurry of users on Twitter and CNET report that the newest Mac Mini released last month is unable to update to the latest version of OS X Mountain Lion, 10.8.2. The update is unavailable through the App Store’s Software Update feature after Apple pulled it for an unknown reason on Friday. Additionally, users received an error when trying to install the update manually through the manual installer made available by Apple. OS X displays an error message of  “Error: OS X Update can’t be installed on this disk. This volume does not meet the requirements for this update.” Customers on the Apple Support Communities also voiced their concern.

The cause of the error is unclear, but what is clear is that for some reason a special version of OS X 10.8.2 is required for the Mac Mini (like the one that was pulled on Friday). Apple doesn’t explain why a special version is needed—perhaps it boils down to the new Fusion Drive that is also set to ship with the new iMac later this month—or why it pulled the update from the App Store on Friday. The best option for 2012 Mac Mini owners now is to stick it out on 10.8.1, because as Twitter user Gerald explained it, the update still didn’t work “after 5 hours and 4 reinstalls.”

There is no word on when the new version of OS X 10.8.2 will be released for Mac Mini owners or if they’ll have to stick it out until 10.8.3. We reported on Friday that Apple will soon release a build of 10.8.3 to early testers soon, and the Cupertino, Calif.-based company will provide new information about the 10.8.3 build during the week of Nov. 26.

Update: Additionally, we learned the update has also been pulled for the 13-inch Retina MacBook Pro and latest iMac…suffering the same issue as the Mac Mini.

Update 2: Apple has released a supplemental update to address the issue.
