I'm running a clean install of Mountain Lion. I have my Caps Lock key mapped to a second Control key.

Whenever I wake my computer back from sleep, it re-sets itself to the Caps Lock key. This did not happen in Lion.

Has anyone else experienced this bug after upgrading?

  • Was this an issue in previous OS versions? Also, what keyboard are you using? Jul 26, 2012 at 22:58
  • Same here. Worked with snow leopard, broke (i.e. not persistent across reboots anymore) after an update to mountain lion. Worked again after a fresh install of mountain lion, then suddenly broke again.

I have the same issue on a 2010 MacBook Air with its internal keyboard. Not every time it wakes up, though. I did a clean install of Mountain Lion. I didn't have such an issue with Lion on the same machine.

  • i have the same problem. do you have Virtual Box installed?

This happens on all keyboards except the internal one. Maybe it doesn't "recognize" the keyboards as the same keyboards anymore.
