Shortly after releasing iOS 6.0.2 to the masses this afternoon, Apple seeded build 12D43 of OS X 10.8.3 to developers. The folks in Cupertino have not listed any new features or known issues, but they asked developers to focus on AirPlay, AirPort, Game Center, Graphics Drivers, and Safari. The last pre-release build was released on Dec. 5. You can check today’s release out on the developer center, while the full release note is below:

OS X Mountain Lion 10.8.3 build 12D43 Seed Note

OS X Mountain Lion Update 10.8.3 is an update to OS X Mountain Lion 10.8. Installation Instructions

  • If you have already installed the “OS X Software Update Seed Configuration Utility”, choose “Software Update” from the Apple menu. Otherwise, proceed with the following steps.
  • Log into your ADC account and download the “OS X Software Update Seed Configuration Utility”.
- After running the installer, the Mac App Store will open automatically. Click on the Updates panel and OS X Mountain Lion 10.8.3 build 12D43 will now be available for download.
- When a newer seed build is available, you will receive a notification to update from the Mac App Store. Click the notification to begin the installation. New seed notes will be posted in the Mac Dev Center.
- To stop receiving new seed builds, go to the Software Update Preference in System Preferences and where it says “Your computer is set to receive pre- release Software Update seeds”, press the “Change…” button. Note: If you are using a computer which gets its updates from a local Software Update server, the OS X Software Update Seed Configuration Utility will reconfigure your machine to use Apple’s Software Update servers. Your computer must be able to connect to Apple’s Software Update servers to install the seed. We recommend that you remove any Configuration Profile that specifies a local Software Update server before installing the OS X Software Update Seed Configuration Utility. Known Issues
