Apple asking Developers to Update Apps for Mavericks
Before the launch of iOS 7 Apple asked developers to submit updates to their apps. That way they would work on iOS 7. Now, Apple is doing the same for OS X Mavericks. They want apps to be updated before the launch of OS X Mavericks, which will probably come in a week.
Make sure your app takes advantage of the great new features in OS X Mavericks when the world’s most advanced desktop operating system becomes available to millions of customers later this fall. Download OS X Mavericks GM seed and Xcode 5.0.1 GM seed, now available on the Mac Dev Center. Build your apps with these latest seeds, then test and submit them to the Mac App Store.
