Apple today released its second supplemental update to OS X Mountain Lion 10.8.2. Supplemental Update 2.0 addresses a bug in OS X’s Keychain, the database that stores saved passwords and logins.
We received a couple tips yesterday about 2012 Macs being unable to update to 10.8.2 due to a password-related bug. It appears that today’s update resolves that issue.
“This update addresses an issue with Keychain that can affect 2012 Mac systems,” according to Apple. If you bought a new Mac this year, then grab this 27MB update now in the Mac App Store.
