The apply magic mouse is in a nutshell absolutely cool, except you might run into a small hitch with it.  You see every 10 to 20 minutes or round there mine disconnects, tells me it has disconnected and a few seconds later reconnects.  Ok a few seconds is all, but let me tell you that it is incredibly annoying so I went on a Google solution hunt.

The few explanations I found were not very helpful, from there is too much wireless activity in your office…ok, there is a conflict with another device, hello they use a large randomly generated key identifier (what are the chances that these devices would share the same key) and that your iPhone bluetooth seems to have an effect.

I turned off the wireless router and all other devices and deactivated my iPhone bluetooth.  Problem persisted.  Then I came across another post that recommended making your Magic Mouse a favorite device under the bluetooth settings and behold success and no more problems for like a week.

So in order to this go to System Preferences->Bluetooth->Apple Wireless Mouse.  Click on the gear icon at the bottom of the list and click “Add to Favorites”.  You might want to restart but most Apple effects are immediate, at least mine was.
