We could not complete your purchase cancelled

having the same issue for the last day or two on a late 2013 MBP, hopefully it gets sorted from apple's end soon - can't run catalina due to specialised scientific software, so hopefully they can help us Mojave users out and patch an update asap!!!

Me too since yesterday. No downloads or even updates on 2 Mojave iMacs "We could not complete your purchase", but other iMac on High Sierra is fine.

If this doesn't get fixed soon, I'll have to downgrade to Hi Si, as there's no way they go to Catalina, as some of my essential software to my business is 32 bit.

I got the same message yesterday. Have a MacBook Pro running MacOS10.14. Spoke with an excellent Apple rep who thoroughly checked my settings and tried numerous fixes. Unfortunately nothing worked. It was suggested that I reinstall my operating system which right now is Mojave.

Same as everyone else here. Two separate computers with the same exact issue. They were both updated to Mojave within the last 5 days. Was hoping to update to Logic 10.5, but I'm not able to do anything in the App Store. I've spent way too much time on the phone/chat with Apple support over the last 24 hours. I have a case open as well, and sent them data from my computer. The rep said she would call me back in a few days (Monday). Not sure what that means.

Being on the phone with Apple for a while. They've been extremely helpful, but they don't know what's causing this issue yet. For me it started before the upgrade to 10.14.6, so I'm sure it's not the update. I will post again once I have new developments.

Same here. Unbelievable, every tool from Apple is a complete disaster, particularly developer tools (just see the ratings there). Yet they are beyond annoying with every single developer´s submission, always with much better apps than theirs

Just spent a couple of hours with Apple. They don't know what's going on. They ran a diagnostic on my computer and now I have to wait to see what comes up. A note, this was happening even before I upgraded to 10.14.6, so I'm sure it's not the update. But everything seems to be off kilt anyways, not really sure what's going on. Don't want to upgrade to Catalina, too many issues with music programs and the whole 32 bit thing. I hope they fix this soon.

I had the same issue yesterday. I contacted apple and they weren't much help. So I just decided to reset/change my apple id password and it already fixed my issue. You can try resetting your apple id password and try logging back on app store with changes.

Now that I have met a bunch of Mojave Logic users. Do any of you guys use Native Instruments FM8? The plugin validator fails every time I attempt to validate it. That is why I am re-downloading Logic, in hopes that this will fix my issue.

I would try restarting your computer one final time, or try logging out and back in to the app store. It definitely worked for me without doing either, but maybe your cache just needs to be cleared to reconnect to the server.

[1] Signed out of iTunes and App Store and made sure to quit both apps.

[2] Deleted caches

cd ~

rm Library/Preferences/com.apple.storeagent.plist

rm -rf Library/Caches/com.apple.SoftwareUpdate

rm -rf Library/Caches/com.apple.storeagent

rm -rf Library/Preferences/ByHost

chmod 755 Library/Cookies

[3] Deleted plist in /Library/Security/Trust Settings

[4] Rebooted the **** machine.

Checked Console: AMSURLRequest: Failed to fetch GUID schemes from bag

NOT WORKING

This is exactly what I did: nothing and both Configurator and App store work.

Not iTunes , but that one is not doing updates since mid March

and Apple is not doing what they should. I can download iOS updates but not apps

I feel for all users who went through so many loops because Apple support suggested them to do that

I would have done it too if it was only me having the issue but when

an issue like this one is affecting so many, the reason is not on your computer

I tried clearing the cache, certs, signing in and out, both Macs are having issues. tried everything. i hope they fix it. we need our apps !!!

i thought i was going crazy. i was about to reset my whole mac for this lol
