I've just installed a brand new MacBook Air with my account and started to get the following errors in AppStore by downloading any application I want.
Please advice on how to proceed. I basically can't use my Mac without AppStore.
I managed to get it to work on my machine finally. I wound up first resetting my password on my Apple ID, and then logged back in to the app store and iTunes. No luck. After that I went to ~/Library/Cookies and deleted everything. Probably overkill. Documentation I've seen says to just delete com.apple.appstore.plist and Cookies.plist . Then I went into the Caches directory and deleted the entire com.apple.appstore folder. (When in doubt, nuke the site from orbit.)
After a reboot I was asked to enter my password for my Apple ID again, and the purchase worked like a charm. I'm using Mojave 10.14.6 on a late 2013 iMac.
I was suggesting as a workaround to go through the purchase and download process on a different machine, and then copy the .dmg file to the computer with the broken App Store.
It should be ok to use the disk image on a different device as long as you are using the same Apple ID for the download.
Are you signing into the app store with the correct Apple ID?
And, have you signed into iCloud with your new device?
FWIW, my Mac works even if I choose not to visit the app store. There are apps included with the OS.
Started happening to me today. I'm on 10.14.6
I noticed an update in System Preferences --> Software Update. I ignore the Catalina upgrade but underneath it said "Supplemental Update" so I agreed and installed it. I come back to my laptop and Catalina is downloaded and ready to install. I clicked nothing of the sort and auto macOS updates are disabled. I closed the Catalina installer and deleted it.
Next thing I know, when I had two app updates using the App Store, they won't update. Same error as original post here except "purchase" is replaced with "update"
I deleted the app (CardHop) and tried to download it from the App Store. Same error, now the word "Purchase" is written.
I signed out of the App Store. Restarted the computer. Flushed DNS. Signed back in, same problem with any app I try to download or update.
When I go to System Information and check Software installations, I see the installed update but no title or version information listed as is visible in other updates.
This is the kind of stuff which really makes me believe Apple is sabotaging any operating system but the current one.
Same here... also on 10.14.6. and both of my Macs are affected (2015 MacBookPro, 2019 iMac).
The error started to occur yesterday evening for me and the wording of the message ist exactly as stated above - "We could not complete your purchase - cancelled". It appears when I try to update or re-download a previously purchased app.
A couple of thing I've tried so far - to no avail:
... any other ideas out there?
Btw: I did not attempt to download the Catalina update - or any update for that matter - so I am inclined to rule that out as well.
Have the exact same problem, started after install of "macOS Supplemental Update" on my OS 10.14.6. Catalina OS upgrade not an option at this time, still have a couple of mission critical older apps, hence all the trouble. Hopefully Apple will understand we are not all made of money and can always buy the latest software and hardware.
Seems to be an Apple store bug because i have the problem in all my computers and all start the same day. My problem is I have an update for Remote Desktop app. when I click to update it come the window below.. Is anyone from apple reading this and checking what is going on. I am not Catalina yet I am Mojave.
I have the same issue, but only 10.14.6. Same Apple ID on 10.13.6, 10.12.5 and 10.15.4 work fine. Tested on 4 different Mojave machines.
Unfortunately some apps are only published at the app store to control license and distribution.
I have the same problem, also on 10.14.6.
I cannot get anything from the App Store, not even downloading items I purchased / installed previously. I get same error, "We could not complete your purchase." then "cancelled" , no matter what I click on.
However, I did not download the Catalina update or the supplemental one mentioned by biensur .
My most recent Apple updates were MRTConfigData and XProtectPlistConfigData on 5/15.
The last time I am sure I was able to use the App Store was on 5/4 . There were auto-updates for Adobe and MS Office since then and I installed AWS yesterday.
I think this is a legitimate bug on the App Store server side.
Some apps are available directly from their vendors. I have not tried today, but I suspect that route should still work.
It seems this problem is specific to Mojave (10.14.6). You could use the App Store on a device that is not affected to download the .dmg file.
Same issue I did everything even change my CC info and still is this an Apple bug or what? App Store tells me I have an update and don't do it. Is a way around it?
I tried to sign out and sign back into iTunes, iCloud, and the App Store, all with the same account and password. It made no difference (MacOS 10.14.6 Mojave).
It seems they just fixed the bug in the App Store.
After I saw this previous message, I tried the App Store without doing anything on my computer and it works!
Thank you btw, whoever fixed it.
We could not complete your purchase - cancelled
