Fix a Slow Mac App Store

Aug 7, 2011 - 23 Comments

Mac Beachball slow It’s unclear why, but the Mac App Store is running a lot slower in OS X Lion for some users, including myself. By slow I mean you’ll encounter nearly constant beachballs as you click from app to app, with the absolute worst offender being the main category sections.

I’m assuming there is an underlying bug or issue with the App Store backend, so a true fix will probably come from Apple to resolve this, but in the meantime I’ve found a couple troubleshooting tips that help to varying extents: deleting caches, and changing a security setting.

Delete Mac App Store Caches

I’ve had some success with deleting the caches, but over time things slow down again. Try this first because it’s the safest method.

  • Quit the Mac App Store
  • From the Mac desktop, hit Command+Shift+G and enter:
  • ~/Library/Caches/

  • Delete everything in this folder
  • Relaunch the Mac App Store

Turn Off Certificate Revocation List in Keychain Access

Warning: this is more of a workaround than a fix, and it creates a potential security risk by disabling the systems revocation list, use at your own risk and read all steps before proceeding:

  • Quit the Mac App Store
  • Launch Keychain Access (use Spotlight or look in Applications > Utilities)
  • From the Keychain Access menu, select “Preferences” and then click on the “Certificates” tab
  • Change “Certificate Revocation List (CRL)” to “Off”
  • Quit Keychain Access
  • Relaunch the Mac App Store

Things should be a lot faster now, but because of the security risk it’s recommended to then go back and change the setting after you have relaunched the Mac App Store. There are mixed reports on if the fix actually sticks around with this method, but for security reasons it is highly recommended:

  • Keep the Mac App Store is still open
  • Open Keychain Access again, get back to the “Certificates” tab
  • Set “Certificate Revocation List (CRL)” back to “Best Attempt”
  • Quit Keychain Access

This second tip comes from MacStories, which I came across when reading @Viticci’s review of the new Core i5 MacBook Air. He also complained of the slowness of the App Store within Lion, and he’s not in the USA which shows this isn’t just a local server issue either.

Keychain Mac App Store slowness fix

Initially when I ran into the App Stores sluggishness and beach balling, I assumed the Mac App Store was just swamped with more users from the Lion switch and downloading process. Now that time has passed and things are still slow, there’s obviously something else going on here, so let’s hope Apple can resolve it soon. The speed issues are negatively impacting the App Store experience, and when everything else in Lion is so fast, it feels very out of place.

    Worked magic for me. Thanks (Y)

    I take it back, I paused the download and when I unpaused it rocketed up in speed nearly jumping to the heady heights of 2-3MB/s… :) I should be getting 6 but still.. Happy with this! Thanks for the tip!
    Apple should really get this sorted.

    Just got a new 9,2 macbook pro 4 days ago. First day, problems with only mac store. Other downloads are perfect and get normal broadband speed. App store downloads running at barely 1MB/s. Dire.
    Checked wired and it was the same. Have now even upgraded broadband from 30Mb to 50Mb(speed test confirmed this speed), and app store still about 1MB every 3 seconds.
    Deleted cache and amended keychain, for the first few secs it worked, it doubled or tripled the awful speed in app store download but now it has slowed to crawl again….

    Support were great but sadly not really much on troubleshooting, they are sending out a new machine which is great if its a bad install of mountain lion or something… but something tells me this wont fix the issue.

    The downloading is so slow!!! Is there a way to make it faster?

    Lion was running like crap and now the update to ML has an ETA of a 1 day, 6 hours. Appalling service from Apple. I think I will make the effort to get Ubuntu running on my MBP and Apple can stick their AppStore

  7. Tack says:

    Yup – deleting the cache worked really well for me :D
    Interested to see if it slows again over time….

  8. Wink says:

    Not much change for me, but thanks.

  9. […] mit der initialen Lion Version des MAS je möglich war. Es hat demnach den Anschein, dass Apple das Zertifikatsproblem in den Griff bekommen […]

    Deleting cache, temp files, language files and other useless binary files, create free space for Mac OS and thus helps to operate faster.
    Although these tasks can be done manually but not every task. For that one needs to go for speed up tools like Stellar speed up Mac

    Thanks for the tip! My applestore was so slow before…

  12. Khaled Abu NaYYaN says:

    wooow your the best …

    Its really works thnx thnx thnx thnx

  13. @ReiVersuri says:

    Any problem with security when put “off” in Certifcate Revocation?

  14. Sheryl says:

    Wow! I used the first tip and the change was nothing short of dramatic. The store popped up immediately upon the start after I cleared the cache, which is amazing considering how laggy it has been lately.

    Got the message “cannot find folder”

    Thanks! The second tip did it for me. I still get the beachball every now and then but by far not as long as before.
