Today Apple released 10.8.3, the third major update to OS X Mountain Lion. To eliminate any potential issues, we generally recommend to update any supported systems using the standalone combo installer available from Apple.com, and not the built-in Software Update.Be sure to back up any important data, and if possible clone your hard drive before applying the update. If you have any issues post-update, boot using UniBeast.Testing is now underway- this post will be updated. Good luck, and let us know how it goes! Report your results here.
