Mac App Store accepting submissions
Apple has now opened the doors for Mac OS X developers to submit their apps to be included in the upcoming Mac App Store. Scheduled to be released within the next three months, the Mac App Store was announced as part of the Mac OS X 10.7 feature set, but Apple quickly revealed it would also be available to existing Mac OS X 10.6 users.
Anyone can develop software for the Mac through Xcode, but if you want to distribute your software through the Mac App Store, you will need to join the Mac Developer Program from Apple. Much like the iOS Developer Program, the Mac Developer Program costs $99 per year.
