I hope someone might be able to help me. I need to perform a fresh install of OSX/macOS on each iMac at home while remotely logging in to my home network. I plan to update each iMac one at a time by remotely logging into iMac_home1 to assist me in installing iMac_home2 and vise versa. I'm confused and need some guidance as to the best way to approach this as there seems to be a few ways to go about it yet I can't take the risk of not knowing what I'm doing and getting stuck. I'm able to remotely connect to either iMac_home# using VNC or once logged into one of the home computers I can share the screen. I want to make sure it's a clean/fresh install yet no one will be there to assist me (i.e. to hold down keys on the keyboard) Edit 1: OS X 10.9.5 is the current OS on both iMacs connected via ethernet.
