Good afternoon, everybody. I'm in the possession of a mid-2010 MBP running 10.12.5 Sierra that I picked up on eBay several months ago and spruced up to fit my liking - SSD, RAM upgrades, battery replacement - and have had no problems with it until date, except for one. Bluetooth is non-operational on this computer. In fact, there isn't even an entry for it under System Preferences. Lately I've taken up an interest in learning Swift programming and wanted to pick up a Magic Mouse/Keyboard for my desk at home, but without Bluetooth I'm stuck with USB only. I was under the impression that Bluetooth and WiFi are integrated together on the same AirPort card; however, I have had no issues with WiFi connectivity whatsoever. What might be causing this? Are there any fixes that I can run via command line? I'm fairly UNIX savvy.
