The Early 2009 Mac Pro—also known as the Mac Pro 4,1—introduced Intel's Nehalem architecture to Apple's line of professional desktop computers in March 2009. The Mac Pro 5,1 used the same interior design but received further CPU updates in 2010 and 2012.

Installing a WiFi Combo PCIe card on my Mac Pro mid2010

Hi guys.

I bought a WiFi PCI-e card for my Mac Pro mid2010. It doesn't work even on Bootcamp Windows 10. The problem is that it came with a power cable which I assume should be connected to a USB pin on a PC motherboard, but as much I searched on my Mac logic board, it does not contain any of such pin. Do you guys think I can use a SATA power port, like the one available for SuperDrive? I appreciate your instruction.

Not sure why it needs power as the PCI slot offers it.

In any case the connection on the board implies its looking for USB power which is 5 Volts at 500 mA (0.5 A) for USB 2.0 and 900 mA (0.9 A) for USB 3.0. So you'll need to find a source within the system to supply that or use an external USB power supply.

Is there a reason you didn't just use the built-in Airport port on the main logic board?

How can I do that? The board on PCI-E is much smaller than the Airport Slot on my Mac's logic board. Also, its original Airport is 802.11n while this one is ac. I wonder if Mac doesn't detect it, how come Windows 10 (Boot Camp) doesn't as well? I tested it on another PC and it works fine. Of course on PC, I connected it to a USB pin on MB.

I don't know if you ever got this figured out or not. But, I was having this problem as well. I finally found an answer. You can use that card, instead of a mini-PCIe card if you want to. You do need BT Data. That's the cord coming off of the card labeled USB Data-/Data+. From my understanding, it is not a power source you need, but you need the Data connection for Bluetooth.

I just realized your card might be Wifi only. I see that you have 3 antennas, whereas mine has 4: 1 for BT, and 3 for wifi. I thought from the "Combo card" in your title that it was a Wifi & BT Card. However, I don't know why it would need Data -/+ if it wasn't BT also. Which is it?

If it is a BT & Wifi like mine, you can use the original BT MoBo header for the data-/+ that you need. you need Do an adapter/new plug to plug into or you can splice the wires into the original BT data cable. the original BT header (next to the BT Card) uses a tiny 4-pin connector, of which you'd only use the top two pins for the Data. Top is Data-, 2nd from top is Data+

Otherwise, if it is wifi only, maybe you could remove the card from the PCIe adapter and see if just the card fits in the mini PCIe slot the original wifi card came in. It looks like the actual wifi card is installed on the PCIe 'sled' in a mini PCIe slot.

These are just my thoughts and suggestions of what to consider. I am by no means an expert on this and learning as I go, while trying to upgrade my 2010 MacPro. You probably have already resolved this problem, since this thread is several years old, anyways. I am dealing with the problem now, hence me stumbling across this post.

Good Luck & God speed!
