Works fine for me. I downloaded it off of Logitech's site and it installed without a problem on both mine, and my mom's iMac. It doesn't install APE either. I just didn't use the CD.Very nice! I've just picked up a MX Revolution myself, and it's most excellent! Far, far, better than the Mighty Mouse anyway!
One word of warning, the Logitech software for OS X is based one the evil, evil, APE. So do not, under any circumstances, try installing it under Leopard. It completely borked my computer to the extent of having to reinstall the OS! Of course, no where on the packaging does it say that it also installs APE [!] !]'>
It detected the mouse fine, and even pops up a small logo when you plug, and unplug the mouse. Other than that, it's a dream mouse
I have been using it all day yesterday, and will all day today. I thought the mighty-mouse was nice, or even my GE Generic mouse (General Electric) that I picked up for $9 out at target. I can't believe how much of a difference a mouse makes when it comes to computer use.
Anyways, thanks for the " 'grats". I would recommend this mouse to ANYONE.
