Question: How to clear mac app store cache? can't download skitch

I'm Under OS X 10.8.2


Today I received an update about skitch. them I clicked the update button. the update process started.

until the progress bar reached 70% it give me an error "Skitch failed to download, Use the Purchases page to try again." them I went to the Purchases page, it give me a red text waring. "an error has occurred" I clicked the INSTALL Button again. it give me the progress bar again but for about 1-2 seconds.

the progress bar is about 80% full but reported "12.88 MB of 12.88 MB less than a minute" them the same error again "Skitch failed to download, Use the Purchases page to try again."


Now I wonder that can I do?

Hi there,


you are not alone, Mac App Store is kinda messed up on ML and nder certain internet connections, I dn't know why.

It's happenning the same to me. I hope they fix this soon, I can download big apps but not small ones... something is wrong on their end...

Hi bennlloyd1

Actually I've tried delete all the content in ~/Library/Caches/com.apple.appstore before you told me.

but it's not solve my problem the Skitch progress still at 80%. and could not be downloaded again or be canceled.


I googled for another hour... the solution is to use the activity monitor to monitor the app store's procress. download a new app to see files opend by the app store. Finially I found the location of the real caches!!!


for me it's

/private/var/folders/dw/w3mz6fc50z2r4qf72g79j9h0x00gn/C/com.apple.appstore


I did rm -rf * under the folder them download again. Problem got solved!

Thanks Beterhans Pan!!! This solved my problem. I was having the exact same problem with the OSX Server 2.1.1 update. I've been looking everywhere for this answer and you nailed it. I closed App Store, deleted all folders under /private/var/folders (using sudo) and voila. My download has restarted _finally_ and life is good.

This works for me when the App Store pages are all blank:


  1. Quit App Store
  2. Use
    Activity Monitor
    to quit the following processes
    • storeaccountd
    • storeassetd
    • storedownloadd
    • storeinappd
  3. On
    Terminal
    delete the following folders:
    • /Users/jj/Library/Caches/storeaccountd
    • /Users/jj/Library/Caches/storeassetd
    • /Users/jj/Library/Caches/storedownloadd
    • /Users/jj/Library/Caches/storeinappd
  4. Restart app store and download!

I found this answer here:


Enabled the debug menu and then select Reset Application; restart the App Store and now the Download button shows up again.


To enable the debug menu, open Terminal and run:

defaults write com.apple.appstore ShowDebugMenu -bool true


That helped me a lot.
