I'm not sure if or when drivers will be available for this. Considering this scanner works perfectly well otherwise, I'm a little peaved.
I got the following response from Canon when I asked about drivers:
Thank you for contacting Canon product support in regards to your CanoScan LiDE 600F and your Mac.
Unfortunately, the LiDE 600F is not compatible with OS 10.9. The scanner can only be installed on Macs running OS 10.8 or earlier. I apologize for this inconvenience.
