Note: The configurations for this tutorial was made on a Logitech MX Revolution mouse, and may vary depending on your model of Logitech mouse.
As of this writing, Logitech has not *officially* released updated drivers that allow installation on Apple’s latest operating system, Snow Leopard, version 10.6. Forum users from Logitech’s official community message boards have posted a way to quickly get Snow Leopard to install the latest version of the Logitech Control Center (ver 3.0) and on how to enable Exposé with your thumb wheel as well.
Install Logitech Control Center 3.0
A user named “powerbookguy” offered these working instructions to install LCC 3.0 on Snow Leopard:
To install Logitech Control Center 3.0 on Snow Leopard (Mac OS 10.6), follow these steps:
1.Alternate-click the LCC Installer and select “Show Package Contents”
2.Navigate to Contents > Resources > Logitech Control Center.mpkg and run this file
3.The installer will run and then request a reboot.
After you have installed the Logitech Control Center and reboot your Mac, your mouse will be functional again. You are also able to customize your mouse via the System Preferences pane that Logitech installs.
Mentioned by “MickeyS” on the thread, as of yet the Logitech mouse will only work when Snow Leopard is running in 32-bit kernel/extension mode. That means if you don’t boot your Mac in 64-bit mode (by holding down the “6″ and “4″ keys, which you probably don’t) then you are fine.. otherwise you’ll have to make this change.
Enable Exposé thumb-wheel feature
All of the mouse features work correctly except for Exposé, because LCC requires that Exposé.app be in the /Applications folder. All you have to do is simply COPY the Expose.app file from the /Applications/Utilities folder to the /Applications folder. DO NOT MOVE THE FILE, COPY IT.
After you do these changes, your Logitech mouse will be able to work again correctly, and you can configure it once again to your liking.
And of course, if you do not want to take any risks, you may wait until Logitech releases updated drivers with Snow Leopard support, but that’ll take some time according to a forum moderator.
