Regarding the ‘keyboard and mouse’ part in your post … I use a wireless set. So the rPi is mounted behind the monitor and only has 2 wires on it: power and HDMI. There’s a USB dongle plugged in that’s for the keyboard and mouse which I rarely use. Specially since I log in remotely. The only time I need the mouse or keyboard is if something bad happened and the rPi won’t boot up normally. But other than that, not needed.

To update electron enter your MagicMirror folder any execute npm install :)

OHHHHHHHHHH… yep I get it now thank you so much for the help and for the speedy response your mirror creation is the best.

I suggest you open a topic on the raspberry pi forum as well… Maybe somebody can elaborate on where we have to look for a solution.
