Hi all, I'm trying to get the Magic Mouse to work with my 2007 iMac (20", 2.4Ghz, 4GB RAM). I've managed to get it recognized via Bluetooth but there are two problems which might be related : there are no Magic Mouse settings in the Mouse panel in the System Preferences (it's just the basic mouse sliders), and on restart the computer sometimes forgets it had a mouse paired to it. On my Mac Pro Quad (2009) the very same mouse is identified and shows the correct mouse preferences panel. Both computers have the same SL version (the latest, with all updates, as of today). I've found a Wireless Mouse package from Apple but when I try to install it on the iMac, I get the message "The system already has a newer version" or something. Please help. Thanks.
