Mac OS X 10.6.7 beta build 10J860 is available for developers starting last evening. The new version of Mac OS X is around 400MB if you opt for a delta update and Apple asks developers to focus their tests on exactly the same areas as before, that is: Safari, the Mac App Store, AirPort, Bonjour, SMB and Graphics Drivers. Starting with the previous version of Mac OS X 10.6.7 beta, Apple asked the developers to test the functionality of the Safari browser, a sign that there are possible important updates prepared for Mac owners.
This new beta version is only available for developers registered with Apple.
