I am tasked unifying a couple of plugins for different platforms. The AU plugins I got fail validation in pluginval:
pluginval v0.2.3 - JUCE v5.4.3
Started validating: /Library/Audio/Plug-Ins/Components/RevoiceProLink.component

FAILED!! 1 test failed, out of a total of 1
Finished validating: /Library/Audio/Plug-Ins/Components/RevoiceProLink.component

But they succeed in Logic:

However, the commandline auval seems to fail as well:

--------------------------------------------------
TESTING OPEN TIMES:
FATAL ERROR: didn't find the component
Although auval seems to be gone anyway, since auval -a
only finds apple components on my system now… (This is Mojave)
Are there different mechanisms to load AU plugins?
Is this an issue with backwards compatibility?
What is the advice to keep my plugins valid for pluginval?
