As that Canon 9000F is an older generation of their 9000 series scanners, it would be unlikely that Canon would update the drivers for it to 64-bit. If Apple's Image Capture will work with the scanner without functional Canon drivers, then that would be a possible solution.
The paid, non-subscription, 64-bit VueScan product supports (flatbed/film scanning) the 9000F without any Canon software or drivers. In the absence of another solution, this would be a less expensive route than a new scanner purchase, extend the life of the 9000F, and deliver Canon independence.
I have owned VueScan Professional since 2010, and continue to use an ancient Canon scanner with impunity. By no means do I receive any compensation or other benefit from Hamrick software for mentioning VueScan here.
