There was this guy called dosdude on macrumors that made these excellent patch sets to get them mostly working with unsupported versions. But it involved a lot more than just firmware. And there were lots of known issues with some configurations. I'll check that software out though, perhaps I can run Mojave on my 2010 mbp, I really miss the dark mode
