I am trying to install Mojave onto a 3,1 Mac Pro, and no matter what drive I use (USB or Firewire) I always get a prohibitory sign. I've already disabled the SIP and have set up dosdude1's patch from El Capitan. No idea what's going on.
One other question; just wanted to be sure - does dosdude's post-install screen make it possible for a non-metal GTX 285 to work with Mojave?
