Logic Pro x not working after Sonoma upgrade

I had the same problem and what I had to do was make sure Rosetta was turned off. Rosetta is used to open third-party plugins, and since the update fixes a lot of the problems we may have had in the past with our plugins not working due to these M1-M2-and M3 chips there is no need to use it.

at the top of your screen click on go, then go to applications, find logic pro x, then right-click and scroll down to get info and make sure open with rosetta isn't checked. You should be able to open logic right up.

if that doesn't work then keep trying or call Apple support.. I hope that will help you..

I'm having the Same problem.

My plugins don't load or connect as well.

I went from Monterey to Sonoma in order to get some of the newer features in Logic. My Apogee Symphony needed a firmware update. many of the Waves plugins are not found. I did a recording session yesterday and Logic quit unexpectedly 3 times. Very annoying. The system goes into overload or hard drive too slow error came up numerous times.

I always expect some pain with a system upgrade. I will keep an eye on this thread.

Still having this problem, submitted multiple feedback assistant items, followed everything on Apple’s support article (“Logic Pro Not Launching”), tried 10.7.9, 10.8.0, 10.8.1. Had three cumulative Sonoma updates in the meantime not fixing the same issue. Only thing left is to reinstall macOS. Come on Apple - it’s a lottery at this point which part of my workflow will get broken in each update. Cannot rely on Apple for stability anymore; just wish there was another DAW as good as Logic I could use in the meantime.

OK, thank you, has there been anything from Apple on this? Logic is a fairly fundamental thing to test when a new release comes out - as one of the few professional pieces of software that Apple offer.

So I am very surprised that they are not on it.

THANK YOU. this completely solved my issue!

[SOLVED]

Reinstall Logic and DO NOT INSTALL any of its sounds. Im guessing its the new AI plugins but just in case if you dont have to usd Logics add on sound dont install them either. Then you will see everything starts to work.

Cheeers!!!

Was there any follow up with this? I seem to be having similar issues. Amp/effect libraries not loading properly, recording doesn't work, and I am getting a weird echo on audio tracks.
