Whenever I plug in my usb wireless mouse, my Macbook Air and Mac Pro both think that the mouse is a keyboard and won't register the mouse's movements at all. Is there a way to fix this?

The mouse is a cheapy Gigaware wireless usb mouse and I'm running OS X Mavericks.

  • Where are you being informed that it is a keyboard? – grg Aug 19 '14 at 10:47
  • Have you tried the mouse on other computers? – William May 6 '17 at 17:41

  • The mouse most likely has extra buttons. – Thorbjørn Ravn Andersen Sep 2 '18 at 9:37

This restored the default mouse behavior for me, though it looks like I had a different problem.

  1. Open keyboard settings in System Preferences > Keyboard
  2. Click Modifier Keys... button in bottom right of panel
  3. Select your mouse from the dropdown
  4. Click Restore Defaults button to restore default behavior.

If that doesn't work, you might also try these instructions for removing your keyboard profiles and then restarting.

  • The Restore Defaults didn't work for me and the linked instruction are now outdated. That file doesn't exist on Mojave (10.14.6). Luckily mine started working after just restarting the computer. – sasquatch Aug 7 '19 at 14:36
