Problem trying to upgrade from High Sierra Zone to Mojave

Recommended Posts

Bggunnz

So I was successful on a Dell Optiplex 790 i7 processor getting High Sierra up and running. Granted it is booting up with Legacy. How can I upgrade that to mojave?everytime I try to boot into the install of Mojave I get unsupported CPU twice and then unsupported PCH. A little help here from any of you veterans.

Running Dell optiplex 790 i7 --->> Do I have to set the boot to UFEI? (If so, How can I upgrade my High Sierra if it currently boots Legacy)
MSI AMD R7 240 ---> Would the GT 710 be better
Everything else is stock

Ok, Mojave is FINALLY running..  adding the -no_compat_check boot flag into your config.plist should skip compatibility check and allow the installation to proceed
