What CPU?
Sierra supports only CPUs with SSE4 support.

Runing Sierra on my optiplex 760 E8400 with 4gb ddr2 and Nvidia Asus 210.To pass the problem of ACPI, you need to boot with your USB key (clover inside) then, go to :

Option > ACPI patching > DSDT Fix mask (0x00000000) > and unselect all the case
Boot args : -x (I can not remember if I needed it or not) ^^"

By unseating them all, it's OK.

I suspect that there is one or two boxes in reality that is problematic but I have not yet had time to determine which, that being said, this poses no problem and you will be Able to boot on the installation.
