Apple opens up Mac App Store for Mountain Lion-based app submissions, iOS cross-platform Game Center games

Following the release of the OS X 10.8 Mountain Lion Gold Master (GM) earlier today, Apple has opened up the Mac App Store to apps and games built using the Mountain Lion APIs. Of particular interest to iPhone, iPod touch, and iPad owners -- Mac games that support iOS and OS X cross-platform gaming can now be submitted.

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.

Apple showed off iOS to OS X gaming at WWDC 2012, using a Stig look-alike in a Game Center, AirPlay extravaganza. It looked flawless, and if it performs in real life the way it did on the WWDC, gaming on three screens is about to get a huge boost.

If you're a developer with a Mac Game Center game in the works, make sure you email us at and let us know.
