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

You are posting the wrong information. Before you post something check your facts. The card you are referring to is Bluetooth: 2.1 NOT Bluetooth: 4.0.

Could you share the correct cheaper link I'm only seeing the incorrect card and I'm really wanting to do this upgrade

Yup !

$ 18 is a good price, go get it !

Good work. This is the correct card.

Not sure on the card exchange but as far as I know the Bluetooth 4.0 is just for the handoff feature the SMS should still work with once updated to 10.10. Please do correct if I'm wrong though.

It was already known that texting and calling through Continuity works via WIFI. But I understand that you don't feel like reading all the posts here, there are a lot ;-)

1. Yes

2. The correct BT chipset is welded on a correct network card

3. No

@smelancon731

You're correct - Bluetooth 4.0 is needed for Handoff, however SMS will work as long as you've updated to Yosemite and gone through the appropriate steps to set it up through iMessage.

No, unfortunately. Just 802.11n

Scroll up in this discussion. There are several links to vendors selling the "...CAX" card.

Has anyone tried this instead of doing the hex stuff?

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.

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!
