Apple posts OS X 10.8.1 update, mends your Mountain Lion

There's a special moment in every operating system's life when it loses its innocent .0 status and grows up. It's OS X Mountain Lion's turn to mature, as Apple has just pushed out the 10.8.1 update for early adopters. Most of the fixes are for issues that plague specific use cases, such as audio output from a Thunderbolt Display or crashes in Migration Assistant. There are a few remedies that a wider audience might appreciate -- a fix for iMessages that don't send and an improvement to Exchange compatibility in Mail, for example. We don't yet know of any surprises lurking underneath, but it can't hurt to have a smoother-running Mac while we investigate.
