What if Ctrl+C doesn't work?

If Ctrl + C doesn't work to interrupt a running command in macOS, you can try the following alternatives:

1. Use Ctrl + Z

• This will suspend the process and put it in the background. You can then terminate it using the kill command.

  kill %1  # Replace %1 with the job number if it's different

2. Find the Process ID (PID)

• If the command is still unresponsive, you can find its PID and kill it:
  1. Open another terminal window.
  2. Use the ps command to find the PID:

     ps aux | grep [your_command]

  3. Use the kill command to terminate the process:

     kill [PID]

  4. If the process does not terminate, you can use:

     kill -9 [PID]

3. Force Quit Terminal

• As a last resort, you can force quit the Terminal application:
  1. Press Command + Option + Esc to open the Force Quit Applications window.
  2. Select "Terminal" and click "Force Quit."

These methods should help you terminate a command that is not responding to Ctrl + C.
