A friend and myself enjoy playing strategic games together (rts or turnbased)and are looking into COH2 (and prehaps COH1). Both are 75% off for the next few days!

My system sager laptop (I7-3630@2.4GHz, 8 GB ram and GTX 670MX) should run both games pretty ok. I assume I should aim for low/medium settings to get good framerate?
For my friend, I am much more uncertain if he can really run the game with enough fps to make it playable. He has a Macbook Air 2015...especially the GPU, an Intel HD Graphics 6000, makes me worried.
Has anyone been able to play CoH2 (or CoH1) on a Macbook air 2015? Is it playable/enjoyable?
