My Macbook Pro will not recognize my Canon Rebel T3i when I plug it in. Please help!

I've installed the necessary software from Canon, but no luck. Any suggestions?

If your Wifi is enabled, it will not work. You have to disable your wifi. I just figured this out now.

Solution also worked for my mac mini running Catalina. Thank you.

I own a EOS Rebel T5i, for years I was able to connect to all of my Macs using the cable that came with the camera. Suddenly none of my Macs recognize the camera. However, Windows 10 will recognize the camera. Note this model is not WIFI enabled. The cable works with Windows. I called support and they said try a new cable? Can someone help?

We’re there any macOS updates between when the connection worked and when it stopped working?

Are they the same computers?

[Right]

Hi,

I recently updated to macOSMonterey, however, the connection stopped long before the update. 

One mac was not updated and the computer does not recognize the camera.
