Bluetooth icon missing on top of the screen

Try opening Settings/Bluetooth. My computer

with the latest software shows a small

box at the bottom of the Bluetooth window

which says "Show Bluetooth in menu bar."

Click that box if it isn't already ticked. If

it is ticked and you still don't see it in the menu bar

I'd try the usual stuff; restart the computer,

Turn the computer off, unplug it for a minute

and then plug it back in and restart it.

Run first aid in the Disc Utility. Reload the system software, but be

**** sure you have a back up before you do.
