Hello,
I don’t know why Apple use such names like Panther, Tiger or Leopard for their Mac OS X software. Don’t get me wrong, I like this names. But why on earth do they call one version Leopard and the next version Snow Leopard? Sometimes searching for a solution for a Snow Leopard problem isn’t easy. But sometimes life is easy …
I own a Canon LiDE 60 scanner and guess what: It didn’t work under Snow Leopard. My search for a current software started at Canon Global 
. After some choosing and scrolling I found cstbosx4934ej4.dmg and lide60osx11131en.dmg. I first installed the toolbox and after that the driver. After a reboot I did some test scans without any problems. The scan buttons on the scanner still work as expected.
Here is the link: Canon U.S.A. : Support & Drivers : CanoScan LiDE 60 .
Bye, Tore
