Where is the misconception coming from that Dolphin was designed for Windows? It may have started on Windows, but the common code works the same across all platforms it supports. The only difference is that Mac has shitty drivers for their GPUs.

Rogue squadron games only just recently became playable. They are still some of the most CPU intensive games to play in dolphin. That said, your CPU isn't very strong. From your specs, I'm guessing it's a 3rd gen i7, which probably isn't strong enough to play Rogue squadron. Find out what the exact model of your CPU is please.
