Apple has just reissued the OS X Mountain Lion 10.8.2 supplemental update for late-2012 Macs, including the 21.5-inch new iMac and Mac mini, as well as the 13-inch Retina MacBook Pro. There aren’t any reasons given for the original retraction of the update, and no noticeable changes in the list of fixes that are included in it.
The most recently released Mac mini shipped from Apple with OS X 10.8.1, but was unable to update to the 10.8.2 upgrade, according to reports, giving the following error: “Error: OS X Update can’t be installed on this disk. This volume does not meet the requirements for this update.”
No announcement was made by Apple about this reissue, but it should allow the more recent iMac, mini, and MacBook Pro models that were affected by the bug to update to 10.8.2. Some recent software updates, including that for iPhoto, require 10.8.2 to run.
