People enrolled with Apple’s annual developer program today received a new beta of OS X 10.8.4 (Build 12E40), the fourth planned incremental update to the company’s Mountain Lion operating system. As it has been doing for the past months to till now, the Mac maker is asking testers to focus their coding skills on Graphics Drivers, Wi-Fi, and the built-in web browser 'Safari'.
To download the new build, developers must use the OS X Mountain Lion Seed Configuration Utility (available from Apple’s developer center) .
Apple has recently released OS X Mountain Lion Update version 10.8.3, which includes the ability to redeem iTunes gift cards using a Mac's built-in camera, Boot Camp support for installing Windows 8, several fixes and Safari 6.0.3.
