How to Speed Up the Mac App Store in OS X Lion

Editor’s Note: Make sure you are willing to pay $2.99 for an app on the Mac App Store.

If you have upgraded to OS X Lion, then you may have noticed that the Mac App Store is running a little slower, as I always saw the spinning beach ball when I first fired-up the App Store. In this tutorial, I’ll show you a method how to speed up the Mac App Store. It worked for me.

  1. First, go to the Mac App Store and search for “Disk Diet”. Download Disk Diet from the Mac App Store. It has a whopping price of $2.99! It’s a 1.0 MB download. Mac App Store link here.
  2. Open up Disk Diet and you’ll see a screen which tells you what it is about. Press “Continue”. (Update: Due to Mac App Store sandbox requirements, when you launch the app for the first time, it will ask you to select your partition. It’s a one time event.) Oh yeah, don’t forget to quit the Mac App Store.
  3. You’ll see a window where you can check off which areas on your Mac you want to clean up. WARNING: Make sure you don’t have any important files you need in those categories. Disk Diet will delete those items.
  4. Select the areas you want to clean up. Be sure to check off “Caches” and “Logs” if you want to speed up your Mac App Store.
  5. Click the “Diet” button and Disk Diet will clear your cache, logs, and anything else you checked off.
  6. Relaunch the Mac App Store. You shouldn’t see the spinning beach ball as often anymore.

That’s it! That should speed up the Mac App Store for you, like it did for me! If you have another tip, leave it in the comments! Also, you can run this app regularly to do a routine cleanup.

P.S. Disk Diet not only clears up cache and logs for you, it also clears up Legacy Code (from PowerPC processors), unused language translations, the Trash, your Downloads folder, and your Mail Downloads folder. (Remember, you can unselect the options you don’t want to clear. You can also choose which language translations you want to get rid of. For example, I unselected Chinese because I sometimes need it. I cleared everything else on the list.)

UPDATE: Added Mac App Store link.
