Mac OS X 10.5.6 update
As anticipated last week, Apple has posted its latest update to Mac OS X, v10.5.6. Available through the Software Update service or direct download, the patch consists mostly of dozens of fixes and performance enhancements, for issues such as sync and graphics. Sync reliability has been improved for Address Book, portable home directories and most notably MobileMe, which should now propagate contact, calendar and bookmark changes within a minute of their being saved.
Graphics changes include "general improvements" for iChat, Aperture, Cover Flow and iTunes, and unspecified performance enhancements directed at gaming. More critically the update attempts to address problems with graphics distortion, triggered by some AMD/ATI video cards.
The size of the update may vary depending on processor platform and the currently installed OS; upgrading from an Intel Mac with v10.5.5 nets a 377MB download.
Other issues addressed by the update include problems with AirPort, iChat, Mail, networking and Time Machine. AirPort connections should now be more reliable when roaming in large Wi-Fi networks, for example, and iChat should no longer log a user out when changing status to invisible via AppleScript. Time Machine should be able to properly locate backup volumes, and among several Mail adjustments is a solution to junk messages being left in the inbox.
Networking changes incorporate stability and performance enhancements for TCP and AT&T 3G connections, as well as Apple File Service, namely when using a home directory located on an AFP server. The ssh Terminal command, lastly, should now be compatible with more ssh servers.
