I'm attempting to transfer files (camera to iMac) utilizing an IFC-200U cable. The computer isn't detecting the camera at all, and I've downloaded the newest software versions that are shown from the Support Downloads Page.
Even though the Canon website lists "Catalina" as the iOS version it's detecting I use, I'm running the updated iOS.
Any advice/help out there on how to be able to get data off of the CF cards w/out needing to get CF readers?
I assume you want to use the Apple software. My T6S shows up just fine on my M1 iMac24 with Monterey.
Sometimes you have to run Image Capture directly to set up the computer for imports. Once you do that, things should happen automatically.
Does your iMac have an SD card slot? If so, that's typically much easier to deal with.
