USB setup for Mac, Windows and Linux
Charge the battery, switch the camera on, turn Wi-Fi off and use a USB cable that carries data. Many micro-USB cables only charge. Quit EOS Utility, Lightroom, Photos and Image Capture first.
Mac: right before you click Connect, run killall -9 PTPCamera ptpcamerad in Terminal. macOS grabs cameras the moment they're plugged in.
Windows: Windows puts Canon cameras on its own driver, which Chrome can't use. Switch it to Windows' built-in WinUSB driver in Device Manager, no download needed. Step-by-step Windows guide. Or skip the computer and use Chrome on an Android phone with a USB OTG adapter.
Linux, ChromeOS and Android Chrome with a USB OTG adapter: usually works as is.
