  2. Make sure that Apple Mac App Store servers are up and running. Go to Apple’s System Status website and check.

Customers may have been unable to make purchases from the App Store, iTunes Store, iBooks Store, or Mac App Store.” As you can see, the Mac App Store was down for some users, and but now it is fixed.
