Apple has released OS X 10.8.3 build 12D54 to developers via the OS X Software Update Seed Configuration Utility listing the same focus areas as before and zero known issues. The build also includes Wi-Fi updates.

Developers receiving the new build are telling 9to5mac that Apple has made some “significant changes to Wi-Fi,” though no other details are provided.

The same focus areas can be found in this build as in the previous one (and the one before it): AirPlay, AirPort, Game Center, Graphics Drivers, Safari.

As usual, the Cupertino company urges testers to install the seed on a system or a partition they are prepared to erase if necessary.

“As this is a pre-release build, it is not advisable to use this software on a production system with information on it that you depend on for your business,” Apple says.

“You should back-up all your data before installing this software and regularly back up data while using this software.”

Apple also says that developers need to fully understand the steps required to reinstall OS X Mountain Lion on their machine, if necessary.

As such, the Mac maker refers testers to knowledge-base article HT4718, which describes the OS X Recovery function in full.

The upcoming OS X 10.8.3 is the third incremental update to Apple’s Mountain Lion operating system. When it’s made publicly available, all Mac users will be able to download and install the software for free.

Everything from the iMac and Mac mini to MacBook Pros and MacBook Airs is supported, as well as the Mac Pro.

The update will include a number of security patches too, which Apple never discloses in the changelogs of beta releases.

The security side of the update will also be made available as a standalone package filled with the necessary patches for those customers who only wish to strengthen their Mac’s security without applying OS X 10.8.3.
