I don't have a supported Mac to install macOS Sierra on, but I have the installer, and all the patches downloaded.
I want to install it to a disk named Sierra, could i put the InstallESD on a USB, and replace InstallableMachines.plist and PlatformSupport.plist, install it, and then do the rest of the work from Mavericks? (kexts, replacing the plists again)
