How can I get my apps back after deleting all data? I recently had a problem with my MacBook Air. I went to Apple and they said they would fix it but all my data will get deleted. I said okay but when I got my MacBook back, I didn't know my apps would get deleted. Some of they apps were iMovie, Pages and Numbers. They were already installed when I first got the MacBook.
Well, when they say "all your data will get deleted" that means apps too.

You can go to the Mac App Store, click on the Purchases tab, and re-install your apps.
