On Monday, Apple seeded the Golden Master (GM) version of OS X Mountain Lion to developers and is now accepting app submissions for the Mac App Store. The apps are to be tailored for OS X Mountain Lion and will ensure that both new and old apps run seamlessly on Mac computers after they are downloaded from the App Store.
Apple sent out an email to all developers, reminding them that they can now download the Golden Master seed on the Mac Dev Center and that they can now submit apps to take advantage of the new features in the update. The email from Apple to registered developers in part, went as follows:
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.
Although the Golden Master version is only available to developers now, the final version will be available in the Mac App Store later this July for only $19.99, down from the $29.99 Apple charged for Mac OS X Lion.
