Apple today provided a third beta seed of Mac OS X 10.6.5 to developers, 10H531. The code is said to have just one known issue remaining, that being VMware. If the company's virtualization software is installed, it can potentially stop USB devices from working when a Mac emerges from sleep mode. Developers are otherwise being asked to focus testing on several areas, such as iCal, Mail, QuickTime, Time Machine and 3D rendering.
