Is it possible to upgrade Bluetooth to 4.0 in Mid 2010 Pro?

At this time point the answer is No. Apple has linked Yosemite directly to the system ID string so these features are limited to certain models not the given Bluetooth hardware it could have been upgraded or added (this could change).

"Hey guys,

I'm not sure this solves your issues. I found this on github a few weeks ago and it worked great.

If you happen to be on the beta release program for Yosemite, you'll have to re-run the install script every time you upgraded. I haven't seen a performance decrease nor a battery life drop. Problem is that it requires an extra bluetooth dongle, certainly precious resource on these laptops.

PM me if you have questions."

"I am researching the same thing. I was thinking of purchasing this and using the continuity tool to enable the feature.

My question is slightly different however, I want to enable airdrop between my phone and my laptop. Will this work for this type of solution?"

Hiey guys, I got another problem…I got same MBP and aidrop dont work with my iphone X ( all other devices with bluetooth work ok ) So my query is if is possible to upgrade bluetooth module new version to fix my problem with airdrop conection. Thanx fo your all replays
