I just purchased the Microsoft Mouse 8000 and after working with it for a long time have finally figured out the following procedure to successfully "connect" the mouse with OS X. I believe this is the best mouse available right now for any bluetooth notebook, Mac or PC.
The steps below have been verified to connect my Microsoft Wireless Notebook Presenter Mouse 8000 on my MacBook Pro Core 2 Duo 2.33 with Mac OS X 10.4.8, updates as of 1/1/2007.
1. Turn on the mouse
2. Press or hold down connect button until light flashes alternating red and green
3. Click Bluetooth tray icon; Browse Device...
4. If the device "Mouse" is not in the list click search, then click browse.
5. Next to search button it will say "Device does not have the necessary services."
6. Click Cancel; Quit Bluetooth File Exchange
7. Open System Preferences; Bluetooth; Devices section
8. Settings section; Click the device ID in the list of your mouse, Add to Favorites
9. Turn Bluetooth Off, Turn Bluetooth On
10. Light should stop blinking and the device will show up with status "Connected: Yes" in bluetooth device list.
Notes:
- The device name comes through as (null) and instead uses the device address for the name but this does not appear to effect functionality. Also OS X does not say that the device is "paired", only "connected" but it this doesn't seem to matter as it connects when available.
- When doing this I also had the Microsoft IntelliPoint 6.1 software installed, I'm not sure if it's necessary. In the Microsoft Mouse preference pane, About Microsoft Mouse, Mouse Info it states "No Microsoft mouse devices found".
- The mouse seems to be more jittery in OS X than it is in windows, possibly because the advanced features of the windows software like battery performance adjustment are not available.
- The left, right and pause/play buttons on the bottom appear to not work.
- The back and forward buttons can be programmed through the Dashboard & Expose preference pane as mouse button 4 and 5.
- It might be possible to use a mighty mouse or the following article to further configure buttons 4 and 5:

- I also have the mouse installed and working with a Boot Camp partition on the same system. After it is initially setup in both OS'es it is not necessary to re-pair the mouse when switching between OS X and Windows.
