Quoting Olivier Tristan <email@hidden>:

I think I have been in the wrong direction all the time.

The issue is not this warning, but I suppose some kind of sandboxing now in
use in the validation process of Logic X under El Capitan

I suppose you are running some kind of inter app Mutex which is not
available under sandbox AFAIK.

In my case, I open some files on the user HD when the plugin opens.

Given this, if this is really the issue, I am definitely in a bad
position...

and I wonder how any sampler would work...

FYI, we implement this for several years but still needed to implement the
old Rez stuff to be successfully validated (at least for 10.7).

On 10.11, we do not get the warning message you pasted but our instrument
are not validated.

Indeed auval is crashing when validating any of our Audio Unit with the
following message:
libc++abi.dylib: terminating with uncaught exception of type
std::__1::system_error: mutex lock failed: Invalid argument

This is shown right after :
AU VALIDATION SUCCEEDED.

Maybe because of this Rez stuff. I'll give it a try and let you know.

In the meantime, I encourage anybody to fill a bug at bugreport.apple.com

So this is maybe related

Don't fix what ain't broken as they say.
