I keep meaning to post about anything that breaks and I learn to fix. I do that a lot but nowhere near as often as I learn and fix things. My latest issue was my iMac‘s webcam not working. I’d just get a black “screen” where my face usually is.
Fortunately, the fix was less scary (sometimes, just typing stuff I don’t know or understand into the terminal is frightening but I’m so desperate, I can’t wait) and much easier than usual.
If your iMac webcam isn’t working in PhotoBooth or FaceTime, for example, type the following into the Terminal:
sudo killall VDCAssistant
You’ll probably have to type your administrator password.
I didn’t even need to restart PhotoBooth.
