How can I add my signature to Preview on a Mac without a built-in camera?
I've got a mid 2012 Mac mini, running macOS 10.11 using a 3rd party mouse and Apple keyboard, connected to 2x 3rd party HDMI displays.
I want to add my signature to the Preview app, so that I can sign documents digitally in Preview without having to print, sign, scan.
In the past I have used a built-in webcam to get my signatures saved into Preview, but I can't do that on this Mac mini.
I have access to another mac with a camera and an iPhone if required.
