Well well well... This is something that does not seem to happen to a lot of people but it could happen to you...
You are trying to show your work to a client or a friend or your spouse or you are trying to demonstrate how Logic works to a fellow producer or student then...
(imagine a horror film soundtrack)
Your Audio Units plug-ins are missing... that crucial 3rd party instrument or plug-in is no more... they are not missing in Soundtrack or in that other DAW you use.
You look in every online forum for help and they all recommend "In Logic Pro open the Audio Units Manager and do this and that..."
Should be easy huh?
But when you try to open the AU Manager IT'S GONE!!! It won't open!!
You search again for a solution on this but there is no one talking about a missing AU Manager... they all talk about missing AU plug-ins but not the whole AU manager.
In Panic you try to install your 3rd party plugins again and NADA!!
You reinstall Logic, and it still does not show up!!
Well OK, enough with the drama here's the solution...
Open a Finder window and go to:
USER\Library\Caches\
Find and delete "com.apple.audiounits.cache"
restart your MAC, open Logic Pro and you shall see this (normally)
Then voilaa!!!You have your AU Manager and AU Plugins back.

Fin.
HAPPY NEW YEAR 2009!!!


didnt work
ReplyDeleteThis described my problem precisely. However the solution didn't work for me either. There is no cache file anywhere on my Mac called "com.apple.audiounits.cache"
ReplyDeletehello have you looked in the right library? remember OS X keeps 2, one for the user the other is a "general" one. hope that works. cheers!

ReplyDeleteGuys you need delete your system cache, try user/system/library/cache
DeleteFind and delete "com.apple.audiounits.cache"
for me i got a program called iboostup which it free up your mac memory or any other program that deletes the cache.
this makes logic pro have to re-scan for the units
