Purging deleted Audio Units from AU Manager ???

I am not one to run here for answers easily found in my manual. For the life of me I can't get rid of old erroneous AU entries after their removal (including after removing them from the Components, and VST folders i.e., Mac HD > Library > Audio > plug-ins). These are AU's like; all of the NI Komplete instruments (sold it and removed it to not be a software theif), trial plug-ins from Rob Paben, Arturia, peavey, freebie like Sampletank and others.

How can I purge these now erroneous entries from the Audio Units Manager breakdown??? I find no way to purge and scan fresh. Getting very cluttered.

Does Logic have an additional plug-in history cache for AU's beyond the location listed above that may require removal as well????

~ Problem persists ~
I have done as you both suggest by removing the cache at the indicated location. Problem remains. Logic seems to be locating some list of the prior installations somewhere in addition to the cache specified. I have used Spotlight to search the hard drive for any file having, or including names of some of the orphaned Audio Units. Spotlight finds nothing on the hard drive. This is getting to be a mystery.
If any of you feel compelled, download a few demo plug ins, then remove them, then go back to AU Manager. You will find that they are still there. Then remove the

/Users/ YOU/Library/Caches/com.apple.audiounits.cache

- after this - tell me that you no longer have these items in your AU Managers indicating "could not be opened" to to far right hand column.
There must be at least one other location that AU Manager inspects to verify the plug-ins on the computer?????

And did you do as I suggest check both plugin locations?

No, there is nothing to do this. It's the plugin files, and the cache, and nothing else.

I have used Spotlight to search the hard drive for any file having, or including names of some of the orphaned Audio Units.


Spotlight won't find stuff in the library locations. You have to go to the plugin folders directly.

If any of you feel compelled, download a few demo plug ins, then remove them,
then go back to AU Manager. You will find that they are still there


I've done this loads of times, and this never happens. I'm 99.9% convinced you just haven't removed plugins you thought you have removed.

/Library/Audio/Plug-Ins/Components/
/Users/ YOU/Library/Audio/Plug-In/Components/

Also check the VST directories while you are there:
/Library/Audio/Plug-Ins/VST/
/Users/ YOU/Library/Audio/Plug-In/VST/

There must be at least one other location that AU Manager inspects to verify the plug-ins on the computer?????


No there isn't, you're just doing it wrong! 😉

OK ~ I have absolutely done precisely as you directed (I had before as well, but wanted to do the routine methodically per your last posting to 100% assure that I conform with the prescribed directive.

I still get 73 Audio Units with 25 which fail validation.

Back ground - I am an astute very capable, computer savvy user as well as an electrical engineer by trade - I do "get it, I did do exactly as you said to the letter. perhaps there could be an orphaned list left by a prior "Tracktion 3" or "Rax" installation which is somehow being noted by Logic's script at the logic boot up sequence? I think that i will have to give in and hit up Logic support. My personality hates to concede defeat in such instances as this. I know that this is something simple/stupid that I am missing. However, it is beyond the basic issue of these noted file caches.
Thanks for your help Bee Jay. <- My wife likes your screen name BTW

Eric - You are the man! I appreciate you input too brother......

What files are in:-

/Library/Audio/Plug-Ins/Components/

and

/Users/ YOU/Library/Audio/Plug-Ins/Components/

Open the terminal utility and type:
ls -dl /Library/Audio/Plug-Ins/Components/* [press return]

and

ls -dl /Users/ YOU*/Library/Audio/Plug-Ins/Components/ [press return]

(obviously substituting your username in the command above)

Are you saying that those folders are now completely empty? Because what you describe is counter to how things work, and the most likely explanation is that you're doing something wrong somewhere (don't take offence by that, it's just sometimes people think they done it right but haven't, without understanding why.)

Perhaps there could be an orphaned list left by a prior "Tracktion 3" or "Rax" installation which is somehow being noted by Logic's script at the logic boot up sequence?


Nope. Audio Unit plugins, the only type seen by Logic, are installed in the two directories above - nowhere else.

I think that i will have to give in and hit up Logic support.


You're welcome to try, but you'll get far better support and help here...

My personality hates to concede defeat in such instances as this.


We're not conceding defeat, but if you want to, well... 😉

I know that this is something simple/stupid that I am missing.
However, it is beyond the basic issue of these noted file caches.

Just to chime in on this: either the OP is missing something obvious and foreheadslappingly simple, or we may have to consult an Appliance Healer...
Quit Logic.
The components are gone from their two possible locations. Trashed and emptied the trash. Right?
You've deleted the darn caches - dragged 'm to the trash and emptied the trash. Right?
Now you start Logic, it begins the scan and validations of all Audio Units.
Are you saying that all your deleted components still show up? Are they also being scanned? Or do they just show up in the Audio Unit Manager after the scan, without actually having been scanned?
If this is so, I would be stumped too. Can't help thinking you've missed something small but obvious in the chain of actions somehow...
Anyway, hope you can get it sorted. Logic Support will probably first tell you this too:

regards, Erik.

I have now opened and tediously searched every folder on my mac, verified that these A.U.'s and any other RTAS VST cousins are gone too. I looked throughout both the Macintosh HD directory and my user directory. Ironically I did find remnants of these files in several unsuspecting locations beyond those others have cited herein. I removed then placed back up copies on another hard drive (Just in case)of all Logic caches. This time when I booted Logic I even had to re-register it because it was so thoroughly cleansed. BUT.....

STILL AU Manager sees whooping 73 AU Plug ins and says: (and yes it actually tries to test them all)

+"Logic Pro will now test 73 installed Audio Unit Plug-Ins to maximize system stability. This Audio Unit validation can take some time. Subsequent launches of Logic Pro do not require this test and will be much faster"+

Seeing as we all go through Plug-Ins, demoing deciding against some in many cases. In my Case, I sold Native Instruments Komplete due to clutter lack of need of so many plugs. I rid all my demo plugs too. It seems all too reasonable that Logic should have a cleansing utility to automate this task thoroughly and correctly."

I am flat out baffled, feeling like a flipping idiot and am just amazed that after over 6 hours of tedious patient work, I still have a nest of orphaned information somewhere convincing Logic that 73 P.I.'s exist. I am going bananas here.

It would be intuitively helpful if Logic had a cache purging feature so that it could again scan the directories fresh for actual Audio Units P.I.'s (not just re seeking old records of prior scans - ie caches) as it did the day it was first installed.

Once again, you are going way beyond the specific steps I asked. Did you do the terminal commands I listed above? I don't want to know about any other directories other than the two I gave you.

Ironically I did find remnants of these files in several unsuspecting locations beyond those others have cited herein.


There's nothing ironic here. Some plugins will have application support content, maybe preferences, some will have some standalone versions in the applications folder, put documentation elsewhere and so on. This is all irrelevant. To show up as a plugin in Logic, there has to be a *.component bundle file in one of the two places I gave you. Period.

This time when I booted Logic I even had to re-register it because it was so thoroughly cleansed.


This means you've probably trashed the Logic Studio System ID file (for the serial) or the com.apple.reglogicstudio.plist file (registration preferences) - again, you're not following the specific troubleshooting advice, and doing stuff that's unnecessary, and probably confusing yourself even more in the process...

It seems all too reasonable that Logic should have a cleansing utility to automate this task thoroughly and correctly


How should Logic know what every plugin manufacturer does? If I make a plugin, and make it put some secret files in secret places, how would Logic know this? Logic/Apple is not responsible for third-party pieces of software.

I am flat out baffled, feeling like a flipping idiot and am just amazed that after over 6 hours of tedious patient work, I still have a nest of orphaned information somewhere convincing Logic that 73 P.I.'s exist. I am going bananas here.


I'd still like you to run the terminal commands I gave you, and let me know the results. Don't do anything else, just that. Then, I'll give you a modified version to see if any component files are hidden in those folders, which might be a possibility.

It would be intuitively helpful if Logic had a cache purging feature so that it could again
scan the directories fresh for actual Audio Units P.I.'s (not just re seeking old records
of prior scans - ie caches) as it did the day it was first installed.


I still do not think this is what's going on here...

What files are in:-

/Library/Audio/Plug-Ins/Components/

and

/Users/ YOU/Library/Audio/Plug-Ins/Components/

Open the terminal utility and type:
ls -dl /Library/Audio/Plug-Ins/Components/* press return

and

ls -dl /Users/ YOU*/Library/Audio/Plug-Ins/Components/ press return

(obviously substituting your username in the command above)

This is what I got:

Last login: Thu Mar 5 08:18:29 on ttys000
kerry-lehrbasss-power-mac-g5:~ Kerry$ ls -dl /Library/Audio/Plug-Ins/Components/*

kerry-lehrbasss-power-mac-g5:~ Kerry$


Additionally - After clearing the cache again just now at: Macintosh HD > Users > kerry > Library > Caches - the again starting Logic, I get this:

*Scanning Audio Units.*

+Logic Pro will now test 73 installed Audio Unit plug-ins to maximize system stability. This AU validation can take some time. Subsequent launches of Logic Pro do not require that test and will be much faster.+

the after the scan I get this:

*Incompatible Audio Units found.*

+While verifying Audio Unit compatibility, Logic Pro encountered 24 Audio Unit plug-in(s) which did not pass the Apple AU validation. These plug-ins have been excluded from further usage in Logic Pro to prevent possible problems or crashes. You can start the AU Manager now to review the validation results or continue the startup process.+

I am stuck in a redundant circle here and can conclude that there must be a hidden file in here, because it is clear that things as they should be to not show all of the old Audio Units which used to reside in this box, but are now long gone.

What now?
