Apple releases OS X 10.8.4 with Wi-Fi & Exchange improvements

Apple on Tuesday released OS X 10.8.4, its latest security and maintenance update for the Mountain Lion operating system for Mac, improving Wi-Fi connectivity and Microsoft Exchange compatibility, and also fixing an issue that prevented making FaceTime calls to non-U.S. numbers.

The OS X 10.8.4 update is now available for Mountain Lion users through the Mac App Store. A system restart is required once the update has been installed, and it is recommended by Apple for all users.

The full list of changes in OS X 10.8.4, according to Apple, are:

Compatibility improvements when connecting to certain enterprise Wi-Fi networks
Microsoft exchange compatibility improvements in Calendar
A fix for an issue that prevented FaceTime calls to non-U.S. phone numbers
A fix for an issue that may prevent scheduled sleep after using Boot Camp
Improved VoiceOver compatibility with text in PDF documents
Includes Safari 6.0.5

AppleInsider was first to report last week that the release of OS X 10.8.4 was imminent, as Apple closed the seed project for developer testing. In a note to developers last week, Apple thanked participants for testing, and noted that materials related to the seeding project would be shut down.

Prior to Tuesday's release, there were a total of eight betas of OS X 10.8.4 released, in which developers were asked to focus their testing on Wi-Fi, Graphics Drivers and Safari. Earlier builds of the software signaled that Apple is also testing high-speed 802.11ac Wi-Fi in OS X, suggesting the hardware capabilities are likely to appear in future Macs.
