OSXWiFi Mac Pro 2009 (4,1) and Mac Pro 2010-2012 (5,1) – Handoff and Continuity Broadcom BCM94360CD 802.11 A/B/G/N/AC with Bluetooth 4.0 macOS Yosemite Mojave Catalina - 10.10+ Upgrade Kit

Mac Pro model 5,1 running Sierra 10.12.3 and all Continuity features including Handoff, SMS messaging, Cellular Calls, Instant Hotspot, Universal Clipboard, and Airdrop are fully functional. Getting Continuity working can sometimes be temperamental, but zapping the PRAM, trashing Bluetooth preferences and logging out/in of iCloud ultimately worked for me. Don't forget to reboot just before logging back into iCloud!As far as installation, it was fairly simple, although somewhat tedious. The instructions are lacking in several areas as follows...1. Technically, you only need to remove the processor sled to get to the Wifi and Bluetooth cards. However, if you also take the extra time to remove the fan housing, the job becomes a lot easier as your full access to the various antenna cables increases greatly. To remove the fan housing, use a 2.5mm Allen wrench to remove the bottom posts and a Philips screwdriver to remove six screws. You'll also have to take out the video card and the video card fan to get clearance. Also, don't forget to unplug the two fan connectors and the speaker wire connection before pulling the housing out of the machine.2. There are four antenna connections and these are not explained. The Mac Pro's three Wifi antenna are labeled 1, 2, and 3, but there is nothing on the card to indicate which cable to plug into which port. Wire 2 is not originally connected and covered with clear plastic sleeve and tucked up underneath the original card. (save the sleeve)Here is the proper final installation as looking at the card, the connections on the left, and the "J" labels on the card...Wifi #3 => J0Wifi #1 => J1Bluetooth (extension cable) => J3Wifi #2 => J23. They tell you to disconnect the 4-wire connector that goes to the Bluetooth card but gloss over what else needs to be done here. You need to connect the 4-wire extension cable to the pigtail that used to be plugged into the old Bluetooth card. The other end plugs into the new Wifi card (MAKE SURE THE GRAY WIRE IS ON TOP).4. Then you'll need to use that two-foot Bluetooth extension cable. It's a bit too long so throw a single loop into it. One end plugs into J3 on the Wifi card, and the other end plugs into the Bluetooth antenna wire that you unplugged from the original Bluetooth card. They don't tell you this, but it's VERY important that you cover the exposed metal where this extension cable plugs into the Bluetooth antenna wire. You can try slipping the extra clear plastic sleeve over this connection, but I couldn't get mine to fit. Instead of using tape, which is ugly and messy, I used some heat-shrink tube.---------Do not expect Continuity to automatically start working after this hardware upgrade... it can be quite temperamental and I don't believe anyone really knows for sure the exact procedure to follow. However, after a few days of trial & error, the below finally worked for me...1. Zap the PRAM2. Trash the Bluetooth prefs file3. Log out of iCloud4. REBOOT (important)5. Log into iCloudNaturally, your iOS devices all need to be on the same Wifi, same iCloud, Bluetooth turned on, and the "Handoff" option checked on all.

It looks like some changes to OSX have made this card not work with continuity/handoff. I have successfully installed High Sierra (10.13.6) on my MacPro 4.1 (flashed to 5.1). I used dosdude1 dot com High Sierra Patcher. Then I ordered this card and installed it. Wifi & BT worked fine but the important features I was after (Airdrop, SMS via iMessage, Instant Hotspot, Handoff) weren’t working. I did some research on the CAT tool (Continuity Activation Tool) which is a software download hosted on github. Turns out, Apple has included a list of disallowed Macs for continuity/handoff and the CAT tool goes in and fixes it up based upon your system board IDs and Wifi/BT card model. So, I backed up my Mac via TimeMachine, disabled SIP, ran the CAT tool and rebooted, all is working like a charm! Do some Googling on it but CAT does allow this card to fully work with High Sierra. I wish that OSXWifi would publish this info on their support site, would have saved me a few hours of research and troubleshooting.

Installed on a Mac Pro 2009 desktop. The installation is a bit tricky. The instructions are not as detail as it should be. Be sure to take pictures of the current connections before you get started. Make sure your antenna cable is connected to the same port. At first, you'll see two antenna's connected to the factory installed card. When you remove the card you'll see a third antenna cable hiding under. Antenna 1 was connected to J1 and antenna 3 was connected to J2. Installed the unused antenna cable to J0 and the antenna cable provided in this product to J3. It's easier to connect the antennas before you screw it down to the socket. There should be a 'CLICK' when connecting the antenna. Disconnect both the wired cable and antenna that is connected to the old bluetooth card that was factory installed. I left mine still screwed in. Connect the USB cable provided with the product to the connector. Connect the antenna provided in this product to the antenna that was affixed to the factory installed bluetooth card. Make sure you PRAM you machine.

I thought I already wrote a review of this product, but I can’t find it. So I’ll post again.I can’t overstate how satisified I am with this purchase. I had a similar kit that was approximately the same price, and it was flimsy & difficult to install by comparison. Don’t get me wrong, neither kit was that difficult to install, and they both worked fine (until the 1st one died). It’s just that the OSXWiFi kit is over the top with quality materials and ease of understanding the included instructions.Contrary to what another user posted, the antenna connection instructions were spot on. It took less than 15 min. Start to finish for the install.Once installed, there are a few terminal commands that need to be executed. I had those instructions saved to a file from the last time I installed a similar kit, but I could find the needed material. So I shot an email off to OSXWiFi and within a few hours, they replied with the copy/paste commands I needed, along with full instructions for anyone who doesn’t know how to use the terminal, disable SIP, reboot, etc...5 min. After I got the email, I was up and running with handoff and Apple Watch Unlock working perfectly.Thanks for a great product, and great support OSXWiFi.
