Apple Mac OS X 10.6.6 Released To Developers

Apple has released the Mac OS X 10.6.6 build 10J521 to developers days before the public release of Mac OS X 10.6.5.

9 To 5 Mac reports that the developer release only contains a single notification: “Contains developer support for fetching and renewing App Store receipts.”

Only last week did the company provide a pre-release version of the Mac OS X update to developers, indicating that the public launch is imminent. However, in a surprising move, the company has again pushed the OS back in beta by releasing the Mac OS X 10.6.6.

The release contains no known issues but details some of the focus areas for the OS including 3D graphics, printing, QuickTime, Time Machine and USB devices.

Mac OS X 10.6.5 is expected to be launched alongside the latest iOS 4.2 update for the iPhone, iPod Touch and iPad devices.

Apple's iOS 4.2 update is rumoured to be set for release on either the 9 or the 12 November, with German tech blogs Inside-Handy.de pitching for the 9th and iFun going for the 12th.
