I am really disappointed by Canon's response to the new Sierra OS upgrade.
1. How does a company the size of Canon not manage to get it's act together during the Beta-phase?
2. Around the time of the release (22nd September?) this was posted on the Canon Europe site: "Canon is planning to provide further information by the end of September and we apologise for any inconvenience this will cause." After thirty-five years in the service industry I know that when you promise a customer something by a certain date you either deliver or, if you cannot, keep them informed.
Canon seems to have done neither...unless someone can point me in the direction of any further news?
Having worked with Fiery, Creo, Xerox plotters, OCE plotters, JDL, HP DesignJets etc., a 2-3 week delay is nothing. Seriously. I've seen drivers for new operating systems delayed by months, years, or just not issued.
Lots of things can also change between a beta candidate and RTM. That's one reason why it isn't always the best idea to update to a new OS immediately.
Anyway. Canon lists the following for OS X compatibility, you can expand the section for Pro printers. Check the page to see when the new drivers are issued.
