I am using Mac OS 12 Monterey but Canon has not done an upgrade to the software yet to run on Monterey. I called support and was told to check back later. That was over a month ago.
Ok finally got to Canon printer tech support today 2-7-2022. If you upgrade to Monterey 12.2 there is currently no driver update at this time. They said to check back in a week. There is an update for Mac OS 11.
