My canon pro-100 ICC profiles disappeared after a software update on my mac. For some reason it was only the profiles originally included with the driver that disappeared, all of the 3rd party profiles were still there after...but I managed to fix it...see below.
Finder -> Go -> Computer -> Macintosh HD -> Printers -> Canon -> BJPrinter -> Resources -> ICC Profiles -> EN01
Then I selected "pro100series.canonicc" (which is a bundle not and actual ICC file)...went up to "show package contents" and then copied and pasted them into the colorsync -> profile folder. Hopefully this helps.
