that's not the point. this macbook is faster than a Windows laptop with a 7200U in it, a cpu released in 2017. there's no reason it couldn't run 10.14.Don't blame Apple - Its not their fault you just bought a 7 year old machine .... be real.
I have an older mac Pro - I read the thread, and maybe once Mojave is beyond early beta versions,
I'll try it on mine - but not just yet!
