I want to prevent users from typing anything on the keyboard, but still show the screen (so usual locking will not help). Unplugging the keyboard is not the answer I'm looking for, what other options do I have?

  • I assume that mouse/trackpad should still be working? – nohillside Dec 14 '15 at 8:04
  • Yes, mouse and trackpad should work – CuriousSuperhero Dec 14 '15 at 8:07

KeyboardCleanTool is a tool which 'locks' the keyboard. It can be enabled or disabled with the mouse.

  • The download speed is so slow, host with github please – Weijing Jay Lin Nov 23 '19 at 18:59
  • @WeijingJayLin This isn’t my software, you can contact the author on their website – grg Nov 23 '19 at 19:00

Try MollyGuard:

MollyGuard is a small menu bar application that enables you to lock and unlock your keyboard and, optionally, mouse or trackpad with a hotkey combination. When locked, no input is accepted from the keyboard or mouse (other than the hotkey combination, otherwise you wouldn't be able to unlock your input devices).

  • Sadly no longer available. Hasn't been updated in ages, and now even their web site is gone – Stephen R Nov 19 '19 at 18:37

I would recommend you KeyboardLocker for Mac. It fits perfectly to me.
