MacOS – Cannot break running process in Terminal

macosterminal

This has been killing me for a while. In macOS terminal, I cannot break a process. I've tried every combination of keys. Command. doesn't work.

For example, if I open a screen session with a serial device. It works fine but I cannot exit screen. The only way to kill it is by using Activity Monitor.

stty-a shows that most things are bound to ^ "key", but this Control + "key" doesn't do anything either.

Best Answer

To exit screen you press ControlA followed by Control\.

You can find a comprehensive list of all the default key bindings in the man page (man screen).
