Hi. I have downloaded 10.12 from App Store, i start the installer, next, next, accept, etc, then it reads a lot of data from the drive as i seen in iStat menus. It says the computer needs to be restarted, i click on restart and nothing happens, no screen with update progress, etc, just a simple restart which boots 10.11.5. If i create an installer USB, can i install Sierra over El Capitan with keeping my data?
