One of the first things to fix was to bring my CanonScan N650U to work with my Mac. Canon offers a plug-in for the CanonScan N650U. I tried MSN Search and some Google Groups but I did not find any helpful solution. Actually I had no idea what to do with the package, so I started the CanonPI CS-U Installer in the package. After the installation, the system needed to restart. After reboot, it was possible to scan images in Office using the Canon plug-in Module CS-U 3.8.
