There is a possibility the magic mouse update 1.0 pre-dates your
current OS X 10.6.5 Snow Leopard; so the more recent update
should already be included in your Snow Leopard 10.6.5 system.

Or, if you need a 'newer' version downloaded, check the Mac's
Software Update app and have it look for a newer version. The
message you got may indicate either you already have a newer
version, or a newer one may be available. This is the rub.
There may be a newer software for the mouse, in combination
with a Keyboard update, as the bluetooth keyboard shares a lot.

The "Wireless Magic Mouse Update 1.0" is for OS X 10.5.8 and
OS X 10.6.1 & Later. You may be able to your computer's System
Profiler to see what application version exists of this mouse update
and it probably was installed in the computer with the 10.6.5 update.
Be sure you have a 1.0 download for Snow Leopard, if there are two.
Another item is more often a cause of concern with the BlueTooth
wireless mouse, in 'pairing' the mouse with the computer, and to
be sure to have the system preference for Bluetooth set for the
mouse to be seen by the computer. These details should be in the
instructions for setup of the mouse, when new.
Since my experience with the fancy new wireless mouse is limited
only to what I have read online, and my best mouse is the original
Pro Black Apple USB mouse (dark green with circuitry visible in it)
perhaps someone will reply with experience w/ BT wireless mouse.

You should be able to get the Mac to recognize the mouse if the
mouse can get a bluetooth signal paired between the devices.
And if the System Preference panel for bluetooth is on and set
to recognize items, etc. Some of my Macs have Bluetooth, so I
do have some familiarity with their control panels; to shut it off.
If you have a tower computer with a metal case, in a few instances
the Mac Pro may not have as good a wireless BT signal as it could;
some users have utilized a USB BT dongle or adapter, so as to use
its external antenna to expand the range to the mouse, further. This
may have only been with earlier model Mac Pro towers, though.
