Bluetooth Mouse

Well, there's nothing to learn here. If you have a Bluetooth enabled
Mac, you simply buy a mouse from the Apple Store and then you start
using it. It's that simple. Click the Bluetooth icon in the menu bar
and then select Setup Bluetooth Device and you should be good to go
in a minute.

However, for the first couple of days I struggled with the mouse
everytime my computer was in sleep mode. When I restarted it, it
didn't remember my mouse and I had to run through the configuration
everytime.

Solution : Close and Open the latch at the bottom of your mouse and
then click it a couple of times. The Bluetooth module then picks it
up automatically and remembers it - like the name I gave it.
