KILL Airplay: (use for Vim / Macvim same Ruby)

boot in recovery (command+r)

in terminal:
csrutil disable

sudo chmod 000 /System/Library/CoreServices/AirPlayUIAgent.app/Contents/MacOS/AirPlayUIAgent

run disable.sh

boot in recovery (command+r)

in terminal:
csrutil enable

I can't seem to get write access to anything inside /System in Ventura. Thoughts?

This may (and probably will) be different in later versions of macOS
