OSXWiFi - iMac 2007 iMac 2008 - Handoff Continuity - Broadcom BCM94360CD - 802.11 A/B/G/N/AC Bluetooth 4.0 OSX Yosemite 10.10+

Product is excellent. Replaced my old BCM94321MC and the original Bluetooth module with this card in my iMac mid-2007 24”. I documented all my steps and posted some before and after pictures. Very easy install, however be prepared to remove your LCD screen to access the back plastic (where your HDD would be), that is where you want to install the “extra antenna”, cut a slit under the thermal foil back, and stick under. Since the back is plastic, your signal will penetrate easily (everywhere else is all shielded, pointless that way). I used a sharpie fine tip and traced around the antenna array, allowing precise install. Works great on Mojave! Follow the jumper instructions on paper, it works beautifully. If you see another original bluetooth module, remove it and put aside, use the antenna from that module and connect to extension, voila. I have read reviews where their assuming it is the Front Panel Apple Logo... wrong! You'll block out that antenna easily. Aluminum does not allow radio-passthrough! Extra antenna.. BACK of iMac.. UNDER foil back, adhere and confirm antenna is connected correctly by that point (things move around as you go), that's it!Keep in mind, those who are revitalizing you old Mac with "dosdude1 Patcher", they added complete legacy support for Broadcom 4321MC (WiFi+BT) it turns out, so those of you will find out you technically no longer require this upgrade card, however you NEED this card if you expect Airdrop/Handoff/Continuety.. etc.

The hardware product is fantastic. It is everything one needs to get their older Macintosh working with 802.11ac and Bluetooth 4.0. I specifically wanted to gain AirDrop and Handoff capabilities on my 2008 iMac. The supplied antenna installation directions did not seem to work.The following connections worked great for me:J0: Supplied WiFi AntennaJ1: BluetoothJ3: Original Gray WiFi AntennaJ2: Original Black WiFi AntennaWith this configuration I also was able to connect the Bluetooth antenna without the supplied extension cable. This helps maintain a better wire management system.The instructions also state that the extra WiFi antenna should be adhered to the back of the iMac's Apple logo. By doing this the antenna rests on a metal heatsink from the iMac's logic board. I opted to adhere the antenna about 6 inches to the right on the back of the iMac's aluminum bezel.Everything works great and I am very satisfied with my purchase!

Extra antenna was missing and the extension cable broke inside my Bluetooth antenna. Absolute garbage. The only positive was amazon took it right back.

Allowed my Mac Pro 3,1 to run the latest macOS Sierra, with all features.

Installed in early 2008 iMac(8,1), wifi works but Bluetooth does not. Contacted customer support twice about this and got no response.

It run well. But the bluetooth module in my imac was not the same as the instruction showed. I pulled it out then everything is OK.
