Logic Pro 10.7.8. Audio Input

i had a problem similar to this what fixed mine was at the top of your computer with your notifications, and battery and stuff theres a yellow mic when logic is open. click on the mic and make sure its not on voice isolation but on standard.

If you have a newer mac, try this.

Check the Control Center on the top right of MacOS menu bar.  It's where your volume control, network setting etc are located. You should see a microphone while Logic is running. Click on it and change to standard. This is a common topic. 

Hope this helps. 

I have this exact problem. Garageband works fine but Logic Pro does not. I have a Motu M6. Just spoke to Apple Support telling them they need to fix Logic Pro as it was working before the upgrade of either macOS 13.4 or Logic Pro 10.7.8 (upgraded around the same time).

Every DAW on the planet and every software is working with my Motu M6 except Logic Pro but Apple Support just said they don't debug problems with external sound cards. Well, guess what the problem is if every other software works with the sound card except the one....

Have y'all contacted the manufacturer to see if they have a firmware update for macOS Ventura?

That did not help me at all. I deleted plist files, uninstalled Logic Pro and installed it from scratch, reset settings, reinstalled my sound card drivers, and installed them again.

The thing is, for me, the only input that works is the built-in MacBook microphone. Not even my Studio Display microphone works with Logic Pro anymore.

Curious if you can make it work!

Fortunately, I can record in Garageband and mix it in Logic.
