I am on a 12" MacBook and when I try to click on the icon to install it says it can't be installed from this disk. So I have to use the USB drive method. Does anyone know the proper way to install this from a USB drive?
Can I simply just update from 10.11 to 10.12 without having to perform a clean install first?
