Apple has released a new software update, OS X Mountain Lion 10.8.2 Supplemental Update 2.0. The code fixes the issues behind an earlier release, and should let the 2012 Mac mini, 13-inch Retina MacBook Pro, and 2012 iMac properly upgrade to v10.8.2. "This update addresses an issue with Keychain that can affect 2012 Mac systems," Apple's notes read.
