Mac OS High Sierra- Plugins not showing up

Several of us had this in another thread and we found that unfortunately Apple is acting like microsoft on this one. Try rebooting your computer and see if when you start logic after a reboot, if it doesn't scan for the new components for you. To be safe, I'd quit logic, reboot, then start logic, and not just count on the OS to reload it because it was already running. Doubt that would matter, but better safe than sorry. It worked for the rest of us on that thread anyway.

Good luck,

The described issue seems to apply to Logic Pro X as well as to Garageband. It is known to Apple now for well over a month and nothing has happened in terms of fixing it so far.

High Sierra is definately the first and the last update that I install right after it came out.

Thanks for your advise which seems to work.

Glad it worked for you too. Now if Apple will just fix it so it works as the instructions say it will. 😉
