Apple Keyboard (A1243) - Function Keys Not Working #

The Apple Keyboard (A1243) was introduced in 2007 and rechristened Apple Keyboard with Numeric Keypad in 2009. Almost a decade later, it is still sold under the same name and model number.

However, there have been two different order numbers for this keyboard with separate system requirements:

MB110LL/A - compatible with OS X 10.4.10 and up
MB110LL/B - compatible with OS X 10.6.8 and up (The function keys will not work as expected if you are running an earlier version of OS X)

The only cosmetic difference between the MB110LL/A and MB110LL/B is the icons on the F3 and F4 keys:

MB110LL/A	MB110LL/B
