You mean the plugin code is OS-independent. That’s right.
What I meant is that you need the GIMP headers and libraries to link your plugin with. These are easy to 
install on Linux. How do I do this on a Mac?

Actually unsigned plugins do work.

But if you sign a third-party plugin, you need to sign it with the 
"com.apple.security.cs.disable-library-validation" entitlement. Otherwise, macOS will block it because its 
certificate is different from GIMP libraries'.
