Download the latest Selphy driver for Mountain Lion (10.8) from Canon’s site.
The following instructions assume that the latest driver package is, but the instructions should be valid for other versions as well. So I thought I would find the solution for you. It refuses, saying “This software cannot be installed as it does not support the version of your current OS.”Ĭanon apparently has no plans to fix it – this printer is no longer supported. Now, if you also have a Mac that runs OS X Mavericks, you are in for a disappointment: there is no 10.9 driver, and the currently latest driver (10.8), which you obtain from here, will not install. I recently bought a Canon Selphy CP900 4×6 photo printer to use at events.
