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.
