Following a two-week hiatus that saw no seeds of the impending update, the Cupertino based Mac maker has reportedly released to its developers Mac OS X 10.4.9 builds 8P2130 and 8P130.
The two builds, for Intel- and PowerPC-based Macs, respectively, were said to weigh in at 166.8 MB and 72.4 MB in bare bones "Delta" form. Slightly heftier "Combo" updates, which pack previous standalone security and other updates, came in at 309.6 MB and 166.8 MB.
In a set of release notes accompanying the latest builds, Apple reportedly informed its developers of the implementation of three new bug fixes since builds 8P125 and 8P2125, bringing the total number of code corrections in Mac OS X 10.4.9 to over 100.
Specifically, Apple said it fixed issues with deleting Bluetooth headsets from the Mac OS X Bluetooth preferences. It also took care of some problems with DiscRecording and the burning of DVDs, as well as others with CoreAudio and AudioConverter.
Again, Apple asked that developers focus their testing efforts around key system components such as Audio, Bluetooth, bonjour, Disk Images, FireWire, Fonts, Graphics, iCal, iChat Video Conferencing, iSync, Rosetta, USB and .Mac Connectivity.
A precise release date for Mac OS X 10.4.9 remains imminent but unknown.
