Works, but limited by quality of Mac camera
It works, BUT for smaller QR codes (which is most of them) you have to hold it further away from the camera than the alignent brackets suggest. You still need to center the code and hold still, but you don’t need to fill the brackets (which makes it too blurry for the computer to make out because the webcam can’t focus that close).
So far I’ve had success with the ones I’ve tried.. :)
