I have an Agfa snapscan e20 and would like to use it from my Macbook. The scanner is an old thing. Is this possible and can you give me software to download? Thanks

When i need the driver i download from ftp site of agfa
was done for mac also

First thing you should do is after you have connected the scanner to your computer, go to Finder, navigate to Applications and then double-click on the "Image Capture" icon. Press the "Scan" button on your scanner. The Image Capture application will recognize the connected scanner and will display a preview of the picture. Select any special options you want for the scanned picture and click "Scan" in the lower-right corner of the preview window. A scanned image of the picture will now be saved to the "Pictures" section of your user folder. I am advising you to try this as your MAC OS might recognize the scanner without the drivers.

If that doesn't work, try the drivers from Agfa website for SnapScan E20. Website doesn't specify for which MAC OS version they are. In addition, here's a link to th manual.
