Q: Can I update my macbook pro early 2011 to use bluetooth 4.0

Yes it works. He stoled my idea, but he wrote a better program with the GUI (I check the code, is the same), so congrats to the guy! Don't worry, it works like a magic. He does also a backup of the kext, like I did, so you can restore the old one in the case something will go wrong.

Well at least we know where the code came from! If it is exactly the same, I might still use your method and not the little program, just because I want to see what I'm doing.

Yes take my script and open it with a text editor, take a look to the code if you want. The code is almost identical, I use the commands "perl" and "xxd", instead he did all the stuff only with "xxd", I don't know why but it works.

So last night (October 26th, 2014) I received my Bluetooth 4.0 CAX card in the mail. I followed the instructions from the earlier posts on how to install the card and perform the terminal commands. I am happy to say my early 2011 MBP now supports AirDrop and Handoff/Continuity. Tested everything and all works great!

Thanks to everybody who helped make this happen!

what is the part number in the front of the airport card that has BCM94331PCIEBT4CAX if i will bought it at apple store?

i tried the following part number 607 8959 and 607 7291 is not available at the official apple store.

I was wondering I'm currently on 10.9 so if I buy the bluetooth card (4CAX) and install it then upgrade to 10.10 will I have to redo any installation ?

The part number on the front of my new "4CAX" card is 607-8958. It came out of a 13" 2012 MacBook Pro. Works great! Love Handoff and AirDrop!

Summary: You don't need to replace the $80 bluetooth card in your computer. You can use a cheap USB dongle instead!

I wanted to use the Knock to Unlock app with my late '11 MBP 15" so I could tap my iPhone to unlock my Mac's screen, so I bought a USB bluetooth 4.0/BLE dongle for under $15 on a major online retailer (I don't see any bluetooth 4.1 dongles available and don't think it's a big deal since 4.1 is so new).

To use the dongle, plug it in and follow these directions. tl;dr: download the "Hardware IO Tools for Xcode" bundle, which requires free registration to access. Get the bundle here by searching for "bluetooth" on the downloads page. Install the "Bluetooth Explorer" app by dragging it to your applications folder and run it. Hit ⌘-k or select Tools>"HCI Controller Selector" from the menubar. Change the option to the listing that isn't Apple (often the name is Broadcom, a major bluetooth chipset designer) then hit the "Activate" button and you're done! Anytime you remove the dongle and reinsert it you will need to activate it again.

I expect this will also work just fine for AirDrop since you're setting the dongle as the the system bluetooth device.

Enjoy living the future again!

P.S. Did you know our machine unofficially supports up to 16GB of RAM (double the 8GB in the specs)?!

Hi Sander! First of all, thanks for the detailed tutorial. Just one doubt, in the link you provide to buy the chip, they claim "The item is "4AX" not "4CAX". They are different with bluetooth compatibility." and you point that replaced the old Bluetooth Board: BCM94331PCIEBT4AX for the new BCM94331PCIEBT4CAX. But since it worked for you, i'm confussed. Hope being clear. Thanks in advance.

The card that you want is BCM94331PCIEBT4CAX....the original should be BCM94331PCIEBT4AX.

Make note of the last three digits....CAX, as that is the one that you want. It worked for him, because he used the one with CAX as the replacement.

Hi Gustavo,

Just like Mike said: you need to make sure that you select a CAX card! Like this: BCM94331PCIEBT4CAX

When you have found the card you can use the continuity activation tool to get every working.

Hope this helps,

gr Sander

Hi,

will it work on late 2011 mac book pros. Also what do you mean by replacing IO80211Family.kext do you want us to delete it?

Hi,

I have succesfully replaced BT/Wifi module on my Macbook pro 13" late 2011 for BT4.0 module. Handoff works great even AirDrop devices are visible on Mac. But I have this problem with this new BT/Wifi module. Notebook wakes up immediately after going to sleep. It completes sleep sequence, white heartbeat led will fade out then the HDD starts spinning.

I have tried switching BT/Wifi modules together with deactivating Handoff via Continuity activation tool.

Here is the results:

• With old BT/Wifi module Macbook sleeps without problems.
• With new BT/Wifi module with old driver Macbook awakes after one second. Same with the new driver after activating via Continuity activation tool.

Here is the console log from All messages.

Pay attention at line 363. Wake reason: ?
