Query: The Rube Goldberg of driver installations on OS X

This is hands down the worst user experience for software and driver installation under OS X. I don't think Canon has actually used a Macintosh. The driver installation stuffit archive expands into an installation application. Launching that produces yet ANOTHER installation application. Somewhere in the process, one of these installation applications launches Internet Explorer (despite it not being my default browser) and displays a bunch of screenshots on how to complete the install. Its all very confusing and Rube Goldberg like. It took me 4 tries to get this thing installed.I also notice that the software uses a fair amount of CPU cycles while idle.I would recommend you skip his product if you are using Mac OS X.
