Q:

Will downloading Mountain Lion from Mac AppStore resume if I restarted/shut down the computer?

I'm about to download OS X Mountain Lion from Mac AppStore, and I wanna know if downloading Mountain Lion will resume if I restarted/shut down the computer?!
Thanks...
Muhammad.

A:

I'm not sure if this is done automatically when shutting down, but you can manually pause downloads in the purchases tab:

The Mac App Store allows to pause and resume downloads.
Also see the Apple support documentation:Mac App Store: How to resume interrupted downloads
