Apple has distributed the third beta version of its Mac OS X 10.6.5 to registered developers for testing.
The company has seeded the third beta version of its upgraded security and maintenance update, 10H531, to developers for testing and trial purposes, tech news site Apple Insider has reported today.
Sources claim that the new beta version possess only one known issue, concerning VMware.
Installing the VMware virtualisation product leads to USB devices to not work properly when the system is woken from sleep mode.
Apple Insider reports that people familiar with the matter have also revealed that Apple has asked developers to keep an eye on other important areas, such as iCal, Mail, USB Devices, QuickTime, Time Machine and 3D graphics.
The 10.6.5 beta version comes in a week after the previous, second beta version was seeded to developers on 19 August.
Industry insiders expect Apple to release the updated version during the music event slated to be held next week.
