NOTE: These options ensure that Bluetooth-enabled devices can wake your Mac and that the OS X Bluetooth Setup Assistant will launch if a Bluetooth keyboard, mouse or trackpad is not detected as connected to your Mac. Restart the Mac Bluetooth Connection on your Mac. Navigate to the Bluetooth preference pane in System Preferences.
No sweat. Try here.

I thought that BT would be built in to your mac Book Pro mid 2010, should be there at the top right of the screen next to the wifi icon, but what do I know? maybe it's turned off???? anyways give that a try. or iogear? No use messing around with a cheap-o BT dongle that says 'windows' on it, but doesn't mention mac at all, and then trying to get it to work somehow...not worth the fuss, frankly.... Hmmm....Mountain lion, eh?? bit of an older cat.....still, if it works for you....*cough* El Capitan*cough**...gosh it's sure dry in here...better get a coffee pronto !!

Bluetooth Dongle For Mac Os X 10 11
Oct 24, 2018 2:28 PM
Want to use Bluetooth on your OS X 10.7 Lion Hackintosh? I went through several super-low-cost USB Bluetooth dongles until I found one that still works after waking the Hack from sleep, which seems to be a common problem for some Bluetooth dongles. I’m only using Bluetooth for my Magic Trackpad though but so far, this dongle works a treat. I got mine from eBay for $1.88 including free shipping (no kiddin’!) from this seller. The item is shipping from China, delivery may take 2 weeks.
