I'm posting this here because I'm not really sure where else to post it. I use Twain-SANE to drive my old canon scanner. I clean installed Mtn Lion and was surprised to see that they don't have a version out of the SANE back-end for 10.8 (at least not that I know of). Has anyone out there in the ether managed to get the SANE back-end and Mac OS GUI working on 10.8 yet?
