OS X 10.8.4 Mountain Lion Finally Fixes Messages

by Josh Centers

Clearing the decks before WWDC, Apple has released the OS X Mountain Lion 10.8.4 update [1], along with Safari 6.0.5, to fix a number of lingering bugs that were missed by the 10.8.3 update back in March (see “OS X 10.8.3 Mountain Lion Fixes Nagging Bugs [2],” 14 March 2013). The free update is available via the Mac App Store, with delta [3] (342.33 MB — from 10.8.3) and combo [4] (809.98 MB — from 10.8) updaters ready for download from Apple’s Web site. Though we haven’t heard of any significant problems with the update, it’s always a good idea to wait a few days to see if any arise.

The most welcome fix is for an issue that caused iMessages to appear out of order in the Messages app. This was a long-standing issue that often jumbled messages and made conversations hard to follow.

Enterprise users will be glad to hear that compatibility has been improved when connecting to certain enterprise Wi-Fi networks. Other fixes for enterprise users include improved Active Directory login performance, improved Wi-Fi compatibility with Active Directory networks, and fixes for file saves over SMB, Xsan, and NFS volumes.

Calendar’s compatibility with Microsoft Exchange has been improved. Also fixed in Calendar is a bug that caused birthdays to appear incorrectly in some time zones.

Other miscellaneous fixes include an issue that prevented scheduled sleep after using Boot Camp, a bug that blocked FaceTime calls to non-U.S. phone numbers, improved VoiceOver compatibility with PDFs, an issue that reset desktop wallpapers on restart, a problem that prevented files from being opened after being copied to a volume named “Home,” and unspecified improvements to mobile account compatibility. A variety of security holes [6] were also plugged.

Included with the 10.8.4 update is Safari 6.0.5 [7], which improves stability for Web sites with games and chat features. Also, 24 memory corruption issues with WebKit were patched, which could lead to crashes or exploits, as were 3 cross-site scripting vulnerabilities.

While these changes are welcome, and possibly the last bug fixes that OS X 10.8 Mountain Lion will see apart from security updates, as we stated above, it’s always a good idea to hold off briefly on updating. However, those who use Messages often will be tempted by the chance to fix one of OS X’s most irritating bugs.
