Exit/save file sudo nano command terminal

You should be able to use either control key on your mac.

ctrl + x

is what you need. Maybe someone is intercepting you ctrl + x

You can attach someother usb keyboard to your mac. maybe he ctrl key is broken.

you could try iterm2

https://www.iterm2.com/

you could get keyboard maestro to see if you can map someother key to the ctrl . reboot maybe needed.

Check System Preferences -> Keyboard -> Keyboard tab -> Modifier keys.

Is the "Control (^) Key:" associated with ^ Control ?

If the physical control key is broken, can you associate another key with the Control function. For example the totally useless Caps Lock key 🙂 (OK I think caps lock is useless, and map it as a second control key; see my screen shot below).

I just pigging backed off of rccharles' suggestion that

...maybe he ctrl key is broken...

and suggested the modifier key change via System Preferences -> Keyboard.

So this was a joint effort really.

I'm glad you found a solution. And you can most likely continue to use your alternate control key for as long as you keep this Mac, and its control key is broken.

Great. Have fun with the terminal.

There should be two control keys. Are both bad? A little odd.

The Macbook Pro only has 1 'control' key on the lower left side of the keyboard between the 'fn' on its left and the 'option/alt' to its the right

Are you thinking Command and Option keys? The Macbook Pro has 2 of those on either side of the space bar.

😊 My mistake.

Hi,

For anyone else experiencing this issue, I would first edit your Modifier Keys (as suggested above) however I would change the Control Key to something else and click OK, then I'd modify again and change back to Control and click OK.

This worked for me. Looks like there was a glitch somewhere and the 'turn it off and turn it back on again' trick did the job.

IMHO I would expect it is more likely to be be a software glitch than a hardware failure.

Cheers,

Matty.
