This works for me (macOS 13.5):

    sudo '/System/Applications/Utilities/Activity Monitor.app/Contents/MacOS/Activity Monitor'

But it's certainly possible that I'm forgetting about some protection I had to disable to make it work.

According to my notes, the reason I saved this command is because it let me see the list of open files and ports. But I'm actually not seeing those when running it now...

You can get open files and ports even without sudo for non-root processes by just hitting cmd+i. Maybe running with sudo might allow you to sample or get files for processes owned by root (presumably the info is same as what you'd get with lsof though). (And by ports it seems to mean network ports. If you want mach ports, you can use lsmp).

That doesn't work on MacOS 14. It fails with a code signing violation. You need to use open(1) for app bundles.

Ye, quite a few apps don't function correctly if you run the executable directly.

  sudo open /System/Applications/Utilities/Activity\ Monitor.app

    sudo open -a Activity\ Monitor
