The printer will still work on Catalina normally, but the included Canon 32 bit software will not. The specific Canon software like the scanner software or image editing application it may come with are not made by Apple. CameraWindow DC 8.10.9a for Mac OS X is software that will install CameraWindow DC on your computer or update a previously installed version of CameraWindow DC to CameraWindow DC 8.10.9a. In this case, replace the battery with a charged one, or use an AC adapter kit ACK-E6 (Separately available).Your computer. If there is insufficient charge left in the camera battery, the camera cannot communicate with EOS Utility. Do not connect the camera via a hub doing so may prevent EOS Utility and your camera from communicating normally. Everything worked fine on OS X Mojave but now that I have updated to Catalina, OBS does not see the Window Capture Feed for the camera.

Rebel T2i running EOS Utility 2 as that is the highest software version available for that camera. I am using an older camera because that is what I have access to.
