These are all the things that I have tried to fix the ‘Bluetooth: Not Available’ error on my MacBook:
- Reset the System Management Controller (SMC)
- Reset the PRAM and NVRAM
- Repaired disk permissions
- Deleted Bluetooth preference files from my Home and System Library folders
And none of them have worked. Looks like my MacBook’s Bluetooth controller is dead. Great.
Update: It’s working again. Apparently all I needed to do was turn the computer off (at the plug), leave it overnight and turn it on again the following morning. How bizarre.
