Specifically, people who claim to have tested the latest pre-release builds of Mac OS X 10.4.7 say the update will offer fixes for audio playback in iTunes, Final Cut Pro, Soundtrack and QuickTime. It will also improve Bluetooth file transfers, mobile phone synching and mouse pairings, these people have said.
The update has been under development at Apple for a couple months and saw its latest seedings on Thursday in the form of Mac OS X 10.4.7 build 8J2133 (Intel) and Mac OS X 10.4.7 build 8J133 (Power PC). In Delta update form -- the bare bones install requiring Mac OS X 10.4.6 -- the updates are said to weigh in at a hefty 130MB and 64MB, respectively.
Testers have also disclosed that Apple has implemented fixes into the release for saving Adobe and Quark documents to AFP mounted volumes, syncing files and other data to .Mac, and using iChat to create chat rooms over the AIM protocol.
