I have a 2008 Mac Pro and want to install a  TL-WDN4800 in it. I can fit it in one of the expansion bays, but the Wi-Fi slot that it needs to connect to is on the far side of the motherboard, it seems. It looks like I would need some kind of extension cable to connect between the card and the slot. Or am I missing something? Does this adapter only work with PCs?
