I am new to this forum, and somewhat new to Retrospect Express 4.3, purchased recently (believe it or not!) in a package. I use a Macintosh iBook G-3 800mhz with an internal DVD-ROM Toshiba SD-R2212 that Retrospect doesn't recognize. I scoured the website and searched the forum without success. Actually I downloaded a couple of items offered on the website, which were not clearly indicated, and didn't serve me. Does Retrospect allow/support 4.3 to continue to function with newer optical devices? If so, how can I get what I need to proceed with my backup?
