Because each keypad has firmware specifically for the proper Operating System and Hardware function, the keypads cannot be interchanged. While some functions may work properly, generally, you will have issues with the PC version of the keypad on a Mac or the Mac version of the keypad on PC. Certain functions will not work properly, particularly in Excel. Additionally, the Mac keypad does not have a NUMLOCK key so it cannot be “Turned On” on a PC.
We recommend a Mac version if you have a Mac and a PC version if you have a PC. The PC versions are, GTC-0077 (Black) or GTC-0033 (White) and the Mac versions are GTC-MACB (Black) or GCT-MACW (White)
