Mac App store takes ages to load up, then open or search for any apps. It works fine but just very slow. It wasn't always like this, just recently.

iMac, Mac OS X (10.6.7)

    Yes, same thing here. This is almost unusable.

    I answered, or rather commented, elsewhere....


    This has also been happening to me and only started happening recently.


    From my observations, it is not due to anything local but rather App Store seems to be causing  downloading several tens of megabytes of stuff from Apple web sites (, among others) and also seems to involve the program ocspd.


    Apple, we await a fix from you....

    I use a guest account with fast user switching until someone figures out this bug.

    AppStore seems to work fine with my guest account, which would suggest a corrupt file somewhere.

    So I would think

    Thanks for the replies.


    It looks like we'll just have to wait for a fix from Apple. It's a shame really, as it definitely puts me off using the App Store. Ah well I don't suppose Apple will miss my measly few purchases:)

    HI everyone,


    This thread contains some additional things you might try:



    Hope that helps

    The v10.6.7 combo update includes some MAS bug fixes that may help.



    Restart your Mac after the combo is installed.


    It's ok to do this even if you are already running v10.6.7

  • flookoco Level 1 (0 points)

    Thanks for your advice. I followed it and the App Store is improved but still takes an age to load and move between categories etc.

  • smartpuppy Level 1 (0 points)

    Unfortunately, none of the solutions so far have worked for me including the 10.6.7 combo update.  Keeping my fingers crossed.

  • Carolyn Samit Level 10 (103,365 points)

    Shouldn't be that slow...


    Login to another user account on your Mac. See if the MAS is slow loading there.

  • flookoco Level 1 (0 points)

    Thanks for the suggestion.


    I created another user account and launched App Store and the program just flew like it was on steroids. Is there something wrong with my main user account? I can't believe the speed difference.


    What can I try now?

  • Carolyn Samit Level 10 (103,365 points)

    From your Applications folder move the App Store app to the Trash. Empty the Trash.


    Now open a Finder window. Select your Home folder in the Sidebar on the left then open the Library folder then the Caches folder.

    Move the and the files from the Caches folder to the Trash

    From the same Library folder open the Preferences folder.

    Move these files Preferences folder to the Trash: and

    Same Library folder open the Cookies folder. Move the file from the Cookies folder to the Trash.

    I know you already installed the v10.6.7 combo but you need to do this one more time. If you still have the original .dmg file, move that to the Trash.

    Reinstall new:


    If that didn't reinstall the App Store app, follow these instructions.


    Get Pacifist


    Pacifist is a utility that can extract files from a .dmg folder.


    Open Pacifist after you install it. In the Pacifist window click Open Package.


    Navigate to the MacOS XUpdCombo10.6.7.pkg. Select that then click Open.


    In the next window click the gray disclosure triangle where you see: Contents of manual


    Then click the triangle next to: Contents of MacOSXUpdCombo10.6.7.pkd


    Then click Applications, then right or control click: App


    Then click: Install to Default Location. That will reinstall the MAS to your Applications folder.

    Thanks for trying to help Carolyn, unfortunately after doing all of the above it is no better.


    The Mac App Store came back up on its own after reinstalling the v10.6.7 combo so I didn't need to go the 'Pacifist' route.


    I have timed the application carring out particular actions as follows, before doing this I closed absolutely every program that was running on my iMac and anything running in the background (Dropbox etc):


    My own account (best time recorded)

    Time to open after clicking icon in dock = 1 min 16 secs

    Time to switch from 'Featured' tab to 'Top Charts' = 1 min 14 secs


    From a new test account

    Time to open after clicking icon in dock = <5 secs

    Time to switch from 'Featured' tab to 'Top Charts' = 2 secs


    This is starting to make me paranoid, as I can't understand why most people have no problems with the App Store.


    I don't suppose this has anything to do with it but here goes:


    I have a warning dialogue that has been popping up every hour or so for the last few months, I don't know what app is causing it so I just click 'OK" and it disappears for a time.


    This is the dialogue:





    Puzzled ??? I know I am.

  • gioros Level 1 (15 points)

    The painfully slow behavior of Mac App Store is related to a security setting in the Keychain Access, namely the "Certification Revocation List (CRL)".

    If you are willing to disable it (if I'm not wrong, it should be off by default), the MAS application will regain the original responsiveness.


    To modify the setting in question:

    - Quit the Mac App Store application

    - Open Keychain Access > Preferences > "Certificates" Tab

    - Set "Certificate Revocation List (CRL)" on OFF

    - Close the Keychain Access' Preferences pane and quit it

    - Open Mac App Store

  • Matthew Barker Level 1 (90 points)

    Yup, that fixed the problem for me.

    Too bad.  Having worked with web security, I like to see that a certificate hasn't been revoked.
