Compatibility of Canon MX870 & MG5620 with new Mac OS Catalina...

[larryis1]

I have not upgraded yet to Mojave to Catalina on my two iMac (27" & 21.5", both 2019 versions).  Does anyone know or have experience yet with OS Catalina compatability with both the AIO Canon MX870 & MG5620 printers?

Your feedback will be greatly appreciated.  

Thanks,  Larry

Thank you so much for responding and helping me -- it worked!!

This worked for me sort of but only works when my old computer is open and seems to act as a server.  When the old computer is closed my printer says it is offline.  Any ideas?  Thanks.

I know this thread is a little old, but it totally worked. I was able to get the MX870 to install. Mine was a completely new install on an iMac 27 (2017). I had to go install the old driver from El Capitan 10.11 and it did act a little like it wasn't going to install at first, but then it allowed me to move forward after dismissing the "not apple approved screen". The scanner driver was installed as well but I haven't tested that it yet.

Thank you dm1723 & leodvthorn.  I had better luck by following leodvthorn's link to install V3.3 older drivers on my iMac with Catalina 10.15.7.  I also got the "incompatible" message and to "Quit".  However, I then found a version V3.4 drivers so went back and installed them.  That one succeeded (maybe 3.3 helped, maybe not).  I setup my Canon PIXMA MX870 to be wirelessly connected using the physical printer's settings dialog (clumsy interface for entering WIFI password, but it worked).  Then I went to my iMac's System Preferences to Add Printer and there it was, allowed me to select the Canon MX Series and successfully completed.  Printed a page, all is working.  The scanner interface showed up as well when adding the printer, but I have VueScan so will likely just use that instead.

V3.4 drivers:
