Hi, I encounter problems after updating macOS to Sequoia 15.5 with plugins loaded with dlopen and dlsym.

$ file /Applications/com.gsequencer.GSequencer.app/Contents/Plugins/ladspa/cmt.dylib 
/Applications/com.gsequencer.GSequencer.app/Contents/Plugins/ladspa/cmt.dylib: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit bundle x86_64] [arm64:Mach-O 64-bit bundle arm64]
/Applications/com.gsequencer.GSequencer.app/Contents/Plugins/ladspa/cmt.dylib (for architecture x86_64):	Mach-O 64-bit bundle x86_64
/Applications/com.gsequencer.GSequencer.app/Contents/Plugins/ladspa/cmt.dylib (for architecture arm64):	Mach-O 64-bit bundle arm64

I am currently investigating what goes wrong. My application runs in a sandboxed environment.

What are the symptoms? The go-to tool for debugging problems like this is dlerror (see its man page) which you can call to find out why dlopen and dlsym failed.

The problem was macOS dynamic generated menu entries. I have yet solved the problem, by moving the plugins to a menu button.
