Debugging Plug-Ins on macOS 27

I’ve just upgraded to macOS 27 and, it seems, I can no longer debug a C++ plug-in I’m working on because Apple’s security blocks the debugger from attaching to After Effects.

 

Specifically, I’m getting the following error:

macOSTaskPolicy: (com.apple.debugserver) may not get the task control port of (After Effects) (pid: 5646): (After Effects) is hardened, (After Effects) doesn't have get-task-allow, (com.apple.debugserver) is a declared debugger(com.apple.debugserver) is not a declared read-only debugger

 

LLMs recommend re-signing AE, but that does not seem to be a reasonable thing to do. I’m worried that doing so might trigger copy protection or break something.

 

Not all issues can be solved by simply logging to files, so, what’s the suggested approach to debugging on macOS 27?
