Apple issues fourth beta of Mac OS X 10.6.5 to developers

Apple on Thursday seeded its fourth beta of Mac OS X 10.6.5 to developers, as the security and maintenance update continues to be tested before its public release.

People familiar with the latest build, said to be known as 10H535, indicated that it features the same focus areas as the previous build, issued exactly one week ago Developers have reportedly been asked to concentrate on 3D Graphics, Mail, iCal, QuickTime, Time Machine and USB Devices.

The latest build is also said to have the same known issue as before, in which having VMWare or Parallels installed may prevent the use of devices connected to a USB port.

Apple of late has been regularly issuing betas of Mac OS X 10.6.5 on a weekly basis. Before last week's build, the previous beta came 7 days before that. And the first build was issued on Friday, Aug. 13.

The current release of Mac OS X, version 10.6.4, was issued in June following WWDC. It packed fixes for trackpads on Apple's notebook computers, and also addressed issues with Adobe's Creative Suite 3. In addition, it included Safari 5, Apple's latest Web browser.
