Mac OS X App Store Not Loading, Try Resetting NVRAM

Not long after upgrading to Mac OS 10.9 the Mac OS X App Store stopped loading on my Macbook Air. Starting the app took several minutes and once the window actually came up it was empty. Clicking buttons in the App Store window did nothing.

I found a suggestion that resetting NVRAM ( the equivalent of PRAM on the old PowerPC Macs ) would solve the issue. In my case that worked. The processing of resetting NVRAM is simple and short ( from ):

  • Shut down your Mac.
  • Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
  • Turn on the computer.
  • Press and hold the Command-Option-P-R keys before the gray screen appears.
  • Hold the keys down until the computer restarts and you hear the startup sound for the second time.
  • Release the keys.

I don’t reboot very often, I usually try to avoid it, but it was worth it to get the Mac OS X App Store app working again.

    You made my day! I was trying to resolve this issue with the App Store for over a month now, and I browsed through Apple’s support forums to no avail.

    I’m posting a link to your post in Apple’s forum.

    Thank you very much, Joseph ! :o)

    Note: when started again, AppStore shows app updates are available, even though I updated the apps minutes ago. I’ll try to find a solution for this problem, but at least now I can browse the AppStore and install apps :o)

  2. Glad it helped.

  3. Only thing now is that as soon as the loading bar finishes on the start up the computer shuts down and when I turn it back on it starts again
