Rispondi a "Is it possible to upgrade Bluetooth to 4.0 in Mid 2010 Pro?"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.
