Private test distributions of the software update continued over the weekend for a fourth consecutive week, bearing Mac OS X 10.4.9 builds 8P125 (PowerPC) and 8P2125 (Intel). The bare-bones software updaters weighed in at 71.9 MB and 165.7 MB, respectively.
Despite a flurry of closely-strung builds in January, which sometimes signals an imminent release, those familiar with the latest seeds say Apple engineers continue to add to a mounting list bug fixes now totaling 95.
In particular, the latest builds are said to include at least eight new fixes over builds 8P122 and 8P2122, which made their way to developers last week. Those fixes reportedly target OpenGL, Sync Services, ImageIO, iSync, and memory leaks in graphics driver code.
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.
Mac OS X 10.4.9 is due for release sometime this month.
