I’ve got a user who is having trouble getting an Audio Unit to load consistently in Logic 10.4.6 (running on macOS 10.14).
He says it loads sometimes in a new/blank Logic session, but when opening an older session that he has added the plug-in to, he gets error dialogs, usually the “Failed to load Audio Unit…” one. Once it throws that error, he needs to re-launch Logic to get the plug-in to load in any session.
So I asked him to open Logic’s Plug-In Manager window, and rescan the plug-in. He sent me the log of the auval scan, and it succeeds… but then the log file ends with the line:
updating properties of AU Cheeseverb by reFuse Software…FAILED!
Googling for this sort of message produces low quality results. Can anyone here shed some light on what “properties” Logic is trying to update? Is there some mysterious Logic caveat I need to watch out for here?
For the record, that line does not appear in an auval scan done on a plug-in from the command line, so it’s not coming from auval itself but from Logic.
Also for the record, I have not been able to reproduce this bug once myself, even using the same “problem” session file as the user.
