I actually never came across this or had reports of it. There are a number of plugins in Csound and they all seem to load without any problems. 
I think the way Audacity loads plugins is different. Csound loads dylibs using dlopen directly and I don’t think this has been affected by signing issues.

I found it almost impossible to get an unsigned encoder plugin to work with audacity in macOS because I couldn't disable the code sign check at all. But signing all plugins seems impractical. Has anyone run into this issue and maybe has some solutions?
