Port 5000 Used by control-center in MacOS

Solution from here:

If port 5000 is being used, and you don't know why, it might be Control Center. Test it by doing:

lsof -i :5000
# prints out:
ControlCe 514 username   16u  IPv4 0xabcd      0t0  TCP *:commplex-main (LISTEN)
ControlCe 514 username   17u  IPv6 0xabcd      0t0  TCP *:commplex-main (LISTEN)

The process running on this port turns out to be an AirPlay server. You can deactivate it in System Preferences › Sharing, and unchecking AirPlay Receiver to release port 5000.
