The much-awaited dedicated App Store for Mac, the genesis of which was announced in October and expected to open in 90 days, is due to open on December 13.

A report by Appletell stated that an inside source has revealed that Apple is targeting Dec. 13 as the official launch date for Mac App Store. It also intimated app developers to ready their software by Dec. 6.

The 90-day time frame would have brought the Mac App Store to market in January. However, if the reports are true, Apple is targeting the holiday season to spruce its sales.

Apple is attempting to replicate the success of App Store for its iOS devices for its Mac. The Mac Store experience was touted to be similar to its App Store when it was announced in October. Like on iPad, you purchase apps using your iTunes account and they download and install in just one step. App updates are delivered directly through the Mac App Store. it had said.

Apple is training users to use its iOS to translate users to Mac OS X. In fact, Apple also gave a sneak-peek of its Mac OS X at the Back to the Mac event. Apple CEO Steve Jobs stated Lion brings many of the best ideas from iPad back to the Mac, plus some fresh new ones like Mission Control that Mac users will really like.

Thus, the flow seems to indicate that its iOS features are merging into Mac OS X, which will create a unified experience for users. Currently many users do not migrate to Mac OS X as they find switching from Windows OS to Mac OS X difficult. This strategy enables users a slow transition from iOS to Mac OS X and keeps the users within its fold.

Thus its Mac App Store is an attempt to create a unified experience across its devices and OS. However, questions also abound as to whether iOS apps will run on Mac OS X someday?
