I can't help you with a scanner only but we went multi-purpose and got a Cannon MX860. It's a printer, scanner and Fax. We do not use the fax but the scanner and printer are very good and rock solid on a Mac. You don't even need to load the Cannon software to use all of the features of this printer.
What do you mean "it doesn't work"? Which model scanner? Have you downloaded and installed the driver for it? Which version MacOS X?I need a scanner recommendation for my mac Book Pro.
I tried my wifes HP that she uses for her PC and it doesn't work
thanksl
