Newest Logic Pro 10.7.8 having problems with many 3rd party AU plugins

This worked for me. Thank you!!!

Try to delete Logic's PLIST file. This should fix the problem:

Delete the Logic Pro PLIST file

1. In Logic Pro, note any custom preference settings that you’ve made, and save any custom key commands that you’ve created.
2. Quit Logic Pro.
3. In the Finder, choose Go > Go to Folder.
4. Enter ~/Library/Preferences, then click Go.
5. Remove the “com.apple.logic10.plist” file from the Preferences folder.
6. If you upgraded from Logic 9 or earlier to Logic Pro, also remove the “com.apple.logic.pro” file.
7. Restart your Mac.

Bro I am in the exact same boat. They told me to contact the 3rd party plug ins and tell them to update their plug ins to the new version of Logic and when I contacted them they said it was already updated, which I find hard to believe since the logic update is barely a week old. Then they said to check my audio settings that may have changed when I updated logic, which they did not. It's really cute ....they're both blaming each other and meanwhile we are sitting in the middle totally screwed. Way to go Logic and 3rd party plug ins for making our lives a total nonsense nightmare.

I have the same problem. It does not happen if you run under Rosetta, and happens less often if you disable Midi 2.0. 10.7.8 is very buggy. I wish Apple allowed us to go back to 10.7.7 as I forgot to backup it...

I feel you, brother! I just had that same call with Apple Support. My soundcard manufacturer (yes, Logic stopped recording from anything except the MacBook microphone), wanted to help me, but I cut them loose since it is a Logic Pro problem. I tried 4 different DAWs, which all work with my external soundcard (Motu M6).

****, even Garageband works 🤣 and all apps that ever needed a microphone. I looked in AppStore and saw the darn thing was updated a week ago... go figure...

Exactly! Once I updated to 10.7.8 my projects won't play, yet plugin manager shows all are verified and all work fine in .7.7. It's a mystery and all Logic support says is to go back to 7.7. I guess that's the good news, we can go back.

This worked very well, thank you. Spoke with two support reps, and neither told me this, although now they say it's in the troubleshooting guide for "If Logic doesn't work" type thing. But they should have had me do this.

Seems to be running fine now.

This worked well for me as well. Logic Pro 10.7.8 has been rock solid running in Native mode for me since. And I'm currently working on finalizing a huge project with lots of demands on Logic and my Mac Studio.

Same issue here. I'm also having issues with multi-timbral recordings also. Logic is receiving the midi notes while recording, but completely disappears once I stop. I have to resort to manually clicking my notes in.

So far, all I've come accross was to download 10.7.7 and turn off auto-updates.

The Logic "team" just traded old bugs for new frustrating ones

Great idea, but didn't change a thing, except that I lost a bunch of preferences! Hadn't been using Logic for more than 3 or four minutes before it started crashing again!

In case this helps anyone:

2017 iMac Pro

3.2 GHz 8-Core Intel Xeon W

32 GB 2666 MHz DDR4 Memory

Ventura 13.4.1 (22F82)

Logic 10.7.8

iZotope Pro suite

SoundToys suite

I thought first the problem was SoundToys. It wasn't, although it certainly causes things to crash faster

Then I suspected iZoptope, particularly Neutron 4. It wasn't, although it certainly causes things to crash faster.

Then I suspected this newer version of Logic didn't play nice with Intel Macs. But it sounds like people running M1 and M2 Macs are also having trouble.

And to make things worse, I can't remember if the problem started before the latest upgrade! (Must be getting old!)

is a Apple officially address this yet? I saw a few suggestions but wanted to make sure before I go chasing 10.7.7 again.

Same issue with Amplesound plug-in.

Not even sure I can get back to Logic Pro 10.7.7 since I just got this computer.

I use Logic Pro 10.7.8

I have a Mac Studio 2022

Apple M1 Max

Mac OS Ventura 13.4.1

Nothing but problems with Logic Pro and third party plugins. It like dealing with the weather. On any given day or hour, Logic stops working for no apparent reason. Totally useless. The only reason I have not changed DAWs is because I have so many logic projects and the new learning curve. FL Studio seems more stable on my MacBook Pro than Logic.

Same issue, other post:

Logic Pro X 10.7.8 crashes on launch (x86… - Apple Community

Perhaps not that smart to update Logic if you have an production project going…
