Apple updates Mountain Lion to 10.8.4 with fix for Messages, Exchange, and FaceTime bugs

OS X Mountain Lion

Though the sun is quickly setting on Mountain Lion, Apple released an update for its current operating system today. This is likely to be the last major update to Mountain Lion as Apple’s new OS is slated to be unveiled at WWDC next week. The update bears the less-than-sexy moniker 10.8.4 and fixes various bugs while adding several improvements. It’s available for download today through the Mac App Store Software Update.

The squashed bugs include issues with FaceTime calls to non-U.S. numbers and enterprise Wi-Fi connections. The update also includes improvements with Microsoft Exchange compatibility in Calendar and improvements with VoiceOver in PDF documents. Lastly, the update bumps Safari up to version 6.0.5, which, according to Apple, “improves stability for some websites with chat features and games.”

One of the biggest fixes included in this update stops iMessages from appearing out of time order, a massive pet peeve for anyone trying to follow a conversation within Messages.
