[macos]newer dolphin versions not using cpu time

[labyrinth153]

I didn't mean slower, I meant much more intensive. I have an i5-4260U, which while it packs a good punch isn't high end by any means. I am assuming that my computer just can't run the new version. I was just wondering if the dual core optimizations were not working or required for some reason, because the version 3.5 of dolphin can even run wii games at near 60fps.
