I'm just curious about a Mojave install method that worked for me yesterday - has anyone else done an alternate clean install where you have a reformatted target drive, High Sierra on another, and the Mojave installer on yet another? I tried using a USB stick but it kept saying I didn't have a metal-compatible GPU (I do) and that Filevault was turned on (it isn't). I thought I would have to do an upgrade, so I started up from the High Sierra drive, opened the Mojave installer from the other drive - and it allowed me to do a clean install to the new System drive. Just wondered if this is a known workaround as I've never seen it mentioned before.
