A new rumor cites an anonymous “inside source” in suggesting that Apple plans to launch its Mac App Store one week from today, on December 13th. According to the rumor, Apple CEO Steve Jobs wanted to launch the new App Store today — and developers were reportedly told to have submissions ready by today — but delays pushed the launch back to next week. First announced last month, the Mac App Store will be OS X’s equivalent to the iOS App Store; a one-stop-shop for software that simplifies the process for users and developers alike. The Mac App Store will not be the only authorized point of OS X distribution like the iOS App Store, of course, but it is expected to quickly become an integral tool for OS X software distribution.
