Recently my Bluetooth on my MacBook Pro stopped working without warning. The bluetooth icon in the top right-hand corner of the screen displayed with a line through it, and showed “Bluetooth Not Available” when I clicked on it. This was REALLY annoying as I use a bluetooth mouse on my Macbook Pro.

Thankfully, it was really easy to fix:

  1. Turn the MacBook off
  2. Wait
  3. Turn the MacBook on

However I’ve discovered that there are many others having the same problem. Sometimes you need to reset your PRAM to correct the issue. To do this, follow these instructions:

  1. Cold Reboot your computer (turn it off, wait, turn it on)
  2. As soon as it begins to power up, hold down the following keys at the same time:
    • Command
    • Option
    • P
    • R
