Can't debug AU in GarageBand, with SIP disabled

Audio Plugins
1

Hey,

I am trying to debug my AU in GarageBand, because i dont get any Sound in GarageBand and Logic, but in AudioPluginHost and Ableton everything works. But it does not seem to work. I disabled SIP and in Ableton i can debug the AU properly, but in GarageBand neither Breakpoints nor DBG() do anything.

I got some Information in xCode:

AUv3Instance.mm:1196  Invalid property id 1843 (scope 0, element 0)

and

AUv3Instance.mm:910   Invalid property id 1098015046 (scope 0, element 0)

and in this Post i found out that

“Property ID” might be referring to the AudioUnitPropertyID enum found in AudioUnitProperties.h

but i cant find the ID’s there.

Now i have some Information that i don’t understand and am not able to get more Information, wich is pretty frustrating.

I would be really thankfull for help or ideas what i could try.

Thanks:)

I have no Logic Pro on my Computer, but i thought that they should be simliar enough to figure the Problem out in GarageBand, if that is possible^^

I had to attach the process of the AU to the debuging in Xcode. Now breakpoints work. But still no DBG() or std::cout output.

output will be visible in the Console output (that is the confusing name of the app to view all debug and system messages)
I had to trace AU stuff like you a year ago or so
