Apple seeded the Golden Master version of its new OS X Mountain Lion. The Build is 12A269. The Golden Master designation means that this version is planned to be the final version of the software released to the public and there will not be any last-minute issues.

In February, Apple first announced OS X Mountain Lion, highlighting a number of features already available in iOS, including Reminders, Notes, Game Center, Notification Center, Messages and more. At WWDC the company previewed additional features, including Power Nab, iCloud Tabs and Dictation. Apple will price Mountain Lion at $19.99 and release it to the Mac App Store in July.
