Like the build that preceded it, Mac OS X 10.5.2 build 9C27 is reportedly free of known issues. It did, however, add several more fixes to update's now expansive list of over 130 improvements.
Among the latest additions were fixes to Leopard's Finder sidebar, desktop backgrounds, iChat's Bluetooth functionality, Time Machine, and disk space management, according to those people familiar with the software.
Again, like previous builds, Apple is reported to have asked that its developers focus the majority of their testing efforts on about a dozen core system components such as Audio Input, Bluetooth, the Finder, Graphics Drivers and Spotlight.
Joining the growing list of subtle refinements in Mac OS X 10.5.2 are several more significant feature additions, such as support for Remote Disc optical drive sharing on existing Macs, a list view in Stacks, and support for Apple's new Time Capsule backup appliance.
