Fine -a little frustrating and inconvenient to reinstall something that worked the other day, but no biggie except I wanted to ensure its data didn’t get deleted along with it, so having the free AppCleaner installed, I made sure to make copies of the files/folders it would delete by default before actually going ahead with the delete (come to think of it I might have left out the deletion of some of its files even though I tried to make sure I had made backups).
We do have a Time Machine drive attached as well, but I try not to rely 100% on a single backup.
That said, after having deleted the app in question, emptied the trash and rebooted the computer I keep getting an error message whenever I try to re-download it from the App Store app (“The operation couldn’t be completed (com.apple.commerce client error 500)”):
Following this I’ve looked up solutions for this and other Mac App Store related errors and tried just about everything, but still no go.
This is what I’ve tried so far:
1) deleted a bunch of App Store related preference files in the ~/Library/Preferences/ folder (as explained here)
2) deleted a couple of App Store related cache files in the /var/db/crls/ folder (as explained here)
3) updated the payment information for her Apple ID
4) logged out and in again of her Apple ID (in multiple places: the Mac App Store app, the “iCloud” system preference, and iTunes)
5) changed the Apple ID password (by going to the Apple account website), then logged into the various locations mentioned in step 4
6) cleared a different cache (from the one in step 2), by deleting everything inside the ~/Library/Caches/com.apple.appstore/ folder (as explained here)
7) opened the following folder: /private/var/folders/ and looked for a sub-folder named com.apple.appstore, which I didn’t find (as explained in the same link as in step 6)
8) Booted the Mac into Safe Mode (as explained here)
9) changed the Kaychain access setting (as described here)
10) changed the App Store app settings via the Terminal app using this command:
defaults write com.apple.appstore.commerce Storefront -string “$(defaults read com.apple.appstore.commerce Storefront | sed s/,8/,13/)”
(as described here, in the same link as in step 9)
11) emptied the App Store app’s temporary cache folder by issuing this Terminal command:
open $TMPDIR../C/com.apple.appstore/
(as explained in the same link as in step 9 and 10)
12) Tried re-downloading a different app that had been previously purchased/downloaded for free from the same Apple ID. This resulted in the same “error 500” message as in my screenshot above
13) Tried downloading a new app (not previously purchased before) -a free one, using the same Apple ID. This also resulted in the same “error 500” message.
14) rebooting, shutting down/powering up the Mac, logging out of the user-account, resetting the PRAM.
15) de-authorizing the Mac (from within iTunes), then re-authorizing it
That’s about it. What else can I try?
