Apple Releases Golden Master Of OS X Mountain To Developers

iTunes Launch Singapore

Apple has released golden master version of OS X Mountain Lion (version 10.8) – the ninth and next major release of OS X.

Apple had released the preview version of Mountain Lion back in February, which included over 100 new features.

It includes include a number of popular apps and features such as Messages, Notes, Reminders, Game Center, Notification Center, Share Sheets, Twitter integration and AirPlay Mirroring from iPad.

OS X Mountain Lion will also be integrated with iCloud – Apple’s Cloud based service that was launched in October and is integrated with iOS 5 for iPhone, iPad and iPod Touch.

It also comes with a new security feature called Gatekeeper, which Apple says will give you control over which apps can be downloaded and installed on your Mac.

Apple also announced some new features at the WWDC 2012 Keynote event such as Dictation, iCloud Tabs and ‘Power Nap’.

The Golden Master version means that it is the shipping version of the software that developers must use to develop and submit apps that are compatible with OS X Mountain Lion. So following the release, Apple has also sent an email to developers requesting them to submit their apps compatible with Mountain Lion.

Make sure your apps take advantage of the great new features in OS X Mountain Lion when the world’s most advanced operating system ships to millions of customers worldwide. Download OS X Mountain Lion GM seed and Xcode 4.4 GM seed, now available on the Mac Dev Center. Build your apps with these latest seeds, then test and submit for review.

You can also submit iOS apps that take advantage of the new cross-platform Game Center Groups, so they’ll be available when OS X Mountain Lion ships.
