Download OS X 10.8.3 Mountain Lion Build 12D38 – Developer News

Testers asked to focus on AirPlay, AirPort, Graphics, Game Center and Safari

Apple has seeded a new beta of OS X 10.8.3 to developers throwing in a tool called “OS X Software Update Seed Configuration Utility,” which allows testers to access new builds in a more natural way.

Developers say that thanks to the inclusion of the new utility Apple is now able to send out notifications to install the new builds through the Mac App Store. As usual, programmers will also be notified by email whenever new betas are made available.

The focus areas inside OS X 10.8.3 Build 12D38 remain almost the same as in the previous builds – AirPlay, AirPort, Graphics and Game Center, are some of the core system elements in need of maintenance.

However, the list of focus areas in this new build also includes Safari. Apple includes no additional information as to what portions of the application are in need of proofing.

Unlike previous betas, OS X 10.8.3 Build 12D38 actually lists some known issues.

According to the people who are familiar with the software, these known issues include “blank or black screens when waking a machine from a sleep state, switching between applications or using VNC to remotely control a Mac,” AppleInsider reports.

Apple has a lot of bugs to deal with in OS X 10.8.3, especially if everyone’s complaints are taken into account.

For instance, a graphical glitch affecting Spaces and Mission Control animations on some Mountain Lion installations is in need of fixing.

We've released a dedicated article discussing the matter which hopefully will get fixed in an upcoming incremental release of the operating system.

Apple doesn’t always list all the new features and bugs in the seed notes accompanying OS X betas, so there’s always a chance of seeing new additions pop up with the final release of OS X 10.8.3 Mountain Lion.

Developers looking to download the new build can visit Apple's Mac Dev Center.
