The Problem: My rMBP refuses to pair with any of my Bluetooth devices. First, allow me to list the steps I have already taken in an effort to fix this problem: Reset PRAM Reset SMC Removed Bluetooth.plist file Browsed through the Bluetooth "Diagnostics Report" available from option-clicking the Bluetooth menu bar icon sudo kextunload -b com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport and sudo kextload -b com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport Relaunching the "blued" process Numerous reboots One reinstallation over the existing install As far as I can tell, the hardware is totally fine. The Bluetooth preference pane works as expected as does the menu item, and the System Profile reports that the Bluetooth card is discoverable. No matter how hard I try, however, I cannot pair either of two Magic Mice, an Apple wireless keyboard, my iPhone, or my headphones with the computer. I confirmed that most of these devices were in pairing mode by checking the Bluetooth pane on my phone, yet my Mac pane remains empty with the usual spinning wheel. One notable detail is that I did just receive my computer back from service, however before I tested Bluetooth, I upgraded to 10.10.2, so I can't be sure what broke! Clearly this is a separate problem from the "Bluetooth unavailable" issue that another recent thread details. Is anyone experiencing this issue or have any other measures to try?
