    According to other sources I've read...

    MB110LL/A: Leopard/Snow Leopard keyboard.
    MB110LL/B: Lion keyboard.
    * F3 & F4 keys are silk screened with different icons to represent Lion's functionality.

    Looking at the boxes personally...

    The MB110LL/A box requirements state:
    Mac OS X v10.4.10 or later.

    The MB110LL/B box requirements state:
    Mac OS X v10.6.8 or later.

  • Mac OS X v10.6.8 or later is required for the Function keys to work with the MB110LL/B, though I think only 10.7 (Lion) supports F3 and F4. The escape key and all the other keys below the top row will work fine on any Mac running OS X 10.4.10 and up.

  • The top row of keys do not function as labeled if you use the /B keyboard with mac OSX 10.5.8. For example: the volume up key does dash board.

  • This keyboard (MB110LL/B) will not work with Windows XP on a Boot Camp 3.2 partition. You MUST have OSX 10.6.8 or later, Windows 7 and Boot Camp 3.3 in order for the Apple special keys to work with Windows XP. I wish Apple would make a Boot Camp update that makes the MB110LL/B keyboard compatible with Windows XP.

  • I have been researching the same thing and can't find an answer. I see that people report the bluetooth keyboard update just had a Exposé and dashboard key swap, but in looking-up tons of images of the wired MB110LL/A and /B keyboards, I don't see ANY differences. The F3 and F4 keys seem to have the same markings in both models. Can anyone confirm?

  • From a mechanical standpoint, the hinges have been reversed under the keys.

    I tried to replace a missing key on a mb110ll/b with a key from a mb110ll/a. No go! Apple decided to mess with us and reverse the hinges on most or all of the keys.

    They are the same model #: A1243
    Maybe you don't mind the keys upside down?
