Hello all, hoping someone can assist. I have a Canon EOS Rebel t5i which has always worked very well. I’ve owned since new for over a decade. I recently tried using the camera as a webcam and ran into issues with the software. I see there was a firmware update for the camera so I updated. Now, the lcd display is non functional when operating on camera battery power. If I plug camera into my computer via USB the screen is functional. Clearly something occurred during the firmware update. Please help as this camera is my livelihood. Running Mac OS 11
