This is a very good scanner which is compatible with Catalina although using a Beta software version at the moment which I needed some assistance from Canon to obtain. It replaces my no longer supported DR 2010.
I just bought this about a month ago after my Fujitsu Scan-Snap died. Boy am I glad I switched to this Canon. Not only does it save space on my already cluttered desk, it's images and ease of use are great! I can scan directly from our FileCabinet software or I can just press the scan button on the scanner for more options, like scan to email, printer, or file. Very convenient! Highly recommend.
