I love GoodTask and have used it for some time. However, now when I try to download/update if from the Apple Store, I'm told it is damaged and won't open. This happens with a few other apps. I've deleted and reloaded with no luck. GoodTask still works on my laptop and iPad, so there is some problem in my iMac. In the meantime, can I download GoodTask from somewhere else?
I think I've tried all the solutions suggested on that site and others. I haven't cleared the cache, however. Will I lose anything useful if I do that?
Cleared the cache, but alas, still "damaged." I logged out of store and logged back in. In the process of all this, I've lost the trial version that was working fine and Setupp won't let me download it again.
I've done that several, as well as with some other apps that have become "damaged." The only successes I've had were (1) I bought OmniFocus again from the Omni folks and (2) I persuaded another company to give me a fresh copy (very nice of them.) The problem is clearly with the iMac and its troubled relationship with the Apple Store. I've tried numerous Terminal suggestions. I've deleted apps numerous ways: trash, launchpad, CleanMyMac. At my wits end. I least I can use Reminders to work with the stuff I put together with GoodTask.
Hmm, sounds really weird. There isn't a way to send a fresh copy (not sure what it means too) since GoodTask is distributed through Mac App Store.
One last suggestion would be removing preferences and see how it goes.
Try below and delete preferences file (after closing the app) and reboot, re-open the app.
Open Finder
On top menu, choose 'Go > Go to folder..'
Copy below and move to the folder
~/Library/Containers/com.hahainteractive.GoodTask3Mac/Data/Library/Preferences
Delete com.hahainteractive.GoodTask3Mac.plist
On top menu, choose 'Go > Go to folder..'
Copy below and move to the folder
~/Library/Group Containers/
Delete U57829932E.group.hahainteractive.goodtask3
Reboot the device
If this doesn't work, it may be an issue connected to your Apple ID on Mac App Store. In this case, I recommend you to contact Apple directly to resolve the issue.
