I am not sure why and quite saddened by this but I can no longer type a capital 'C' on my keyboard for my Mac mini running OS X Yosemite. I have run through all of the shortcuts in System Preferences->Keyboard->Shortcuts, but Shift+C is not listed there, anywhere...

What is causing this, and how to fix it?

    And for context, the (5) capitalized C's above were entered with Cap Locks! XX(

    Have you take that keyboard to another conputer or tried another keyboard on the Mac Mini? My suspicion is a hardware failure is causing this.

Have you taken that keyboard to another computer or tried another keyboard on the Mac Mini?

The most elegant solution to your problem would be if it's a hardware issue on that specific keyboard.


First of all make sure your keyboard is working properly. That would be a great first step in figuring out if there is a problem with the hardware. If it is not your keyboard, then I would try to turn of your Mac and turn it back on. If the problem still persists, then you would actually have to add a shortcut yourself

  • Choose Apple menu > System Preferences, then click Keyboard.
  • Click Shortcuts, select App Shortcuts, then click Add (+).
  • Click the Application pop-up menu, then choose an app. If you want to set the same key combination for a menu command that appears in many apps, choose All Applications.
  • If the app you want to select doesn’t appear in the list, choose Other, then locate it using the Open dialog. Some apps may not allow you to set keyboard shortcuts.
  • Type the menu command for which you want to set a keyboard shortcut in the Menu Title field.
  • You must type the command exactly as it appears in the Application menu, including ellipses and any other punctuation. To type an ellipsis, use three periods without spaces.
  • Click in the Keyboard Shortcut field, press the key combination that you want to assign to the menu command, then click Add (+).
  • You can’t use each type of key (for example, a letter key) more than once in a key combination.
  • Quit and restart any apps you’re using for the new keyboard shortcut to take effect.
  • If you assign a keyboard shortcut that already exists for another command or another app, your new shortcut won’t work. Find the menu command that’s using it, then reassign the keyboard shortcut for that item.
  • To remove a customized shortcut, click Delete (–).

    How does this address the problem of a non-working "Shift-C" key combination?

  • @patrix He can add his own combination such as CAPS-C-CAPS to SHIFT-C to address the problem of a nonworking shift c comination Sep 27, 2015 at 16:40

    Using CAPS instead of Shift doesn't need any shortcuts at all. Shortcuts are used to access menu commands, not standard letters.
