Logic 12 - Update and App Store Authentication issue

Upgrade from 11.2.2 to 12.0 on an Apple Silicon machine worked fine

Upgrade from 11.2.2 to 12.0 on an Intel machine failed.

Deleted the whole App on the Intel iMac and reinstalled it back from the App Store. Fixed the issue for me.

Same issue here and for me, as Emoccio said, the issue seems to be associated with my Apple ID. I have two and was signed in to the App Store with a different ID to the one I used to purchase Logic Pro originally. I signed out (Store > Sign Out) and the App Store then seemed to default to my other Apple ID where I could see Logic Pro Listed as one of my previous purchases. I opened the app from there and it finally launched.

We are experiencing the same issue. By logging into the App Store using our App Purchasing details, we can get Logic to work but we have multi-user Macs so not practical to give these details to every user. No fix posted yet. Might be time to use Windows and another solution, like Pro Tools or Cubase.

Apple needs to fix that.

Contact apple support, they are able to merge your accounts. But you need to trigger the process.

We are a college using Logic and have this problem. Have been told by Apple that this is a known issue and is how Logic is communicating with School Manager or Business Manager for multiple devices.

This has brought our whole department to a standstill with students desperately needing to get exam work done!!

Come on Apple this is just not right!!!!!

I have the same Problem on my mac MINI M4 and with my macbook pro ! It must be a bug. But not everybody seems to have it or maybe they are allways online nowadays !! I Hope Apple will realize the Problem and fix it !

My wife bought Logic pro years ago with her apple account but we have the family sharing plan; is this something that is an intentional change to force users to buy the software per user? Otherwise, if I login to the App store under her credentials on my mac mini, Apple might block me from logging into my own apple account for 90 days as it did one time when I was trying to get Apple tv + to work!

Thanks for the idea, but not doing that. Complicated, long waiting period, have to eliminate several things that i still want, the two accounts have to be in the same area, etc, etc.

And why should i take so much trouble for a mistake from Apple? It worked until the last update. Apple should fix it.

I have just encountered this problem on one of my network MacBooks when updating to Logic Pro 12. As we roll these apps out using the Volume Purchasing Program, I am unable to login to the App store and fix it the traditional way. We can't be the only VPP users suffering with this problem though so I'd love to know what other organizations are doing.

Luckily, the other 40 devices haven't rolled out the update yet and I have now turned auto-updating off. I do hope Apple provides a fix soon as this is going to be a massive headache otherwise.

This is insane.

Unable to launch Logic when not connected to the internet even after previously authenticating.

Completely absurd, I'm regular in situations/places with no internet and need to WORK.

Dumping Logic if this isn't fixed soon.

This is happening to me too. I teach Logic at a college. This sucks

At least those other application won't limit you or attempt to keep track of who is using the software. This seems awfully heavy-handed.

Hopefully it will be fixed soon.

I just encountered this issue.

Do we already have a solution for this? I am in the middle of a project in logic and I can't finish because of this.

can someone help us with this?

Thank you
