Chosen Solution
Hi, I would like to upgrade my iMac 2011 EMC 2429 to bluetooth 4.0. The card installed in the iMac is the BCM92046MD. Is there a compatible BT 4.0 card I could buy and install? Please help if you can… All the best, Tom
Hey guys, You probably know this already but the solution is here: http://www.osxwifi.com/apple-broadcom-bc… It works great! All the best, Tom
IMHO it’s not worth the work/expense. Bluetooth 4.0 is mostly an energy saving delveopment for mobile devices (like phones and tablets). ‘‘You don’t need it… will give you little noticeable performance boost to upgrade. . . if you could locate a card and driver (extension/EFI update) that would work on an iMac. If this answer is acceptable please remember to return and mark it.
Hi jjustinschultz, For the MBP you need a BCM94331PCIEBT4CAX chipset - the one you have in your 2011 MBP is BCM94331PCIEBT4AX. You can open the computer to double check but this is probably it. I got mine on ebay from a 2012 MacBook Air. Once you install the hardware you need to hack the .kext files, the tutorial is here: http://forums.macrumors.com/showthread.p… Post #848 That’s it, everything works and this mod is +- $50 with shipping. For the iMac, we need to figure out what chip with BT 4.0 LE is compatible, the rest is only about modifying the .kext files. Tom
Hi Tom, I unfortunately don’t have an answer for you, but am very interested what BT4 chip you put into your Macbook Pro 2011 and the kext mod. I am in the exact same boat as you with the same 2 machines looking to get Continuity to work. thanks.
