I also have Diablo 3 on my Mac Book Pro 2011.
Intel HD Graphics 3000 384 MB
2.7 G.Hz Intel Core i7
4 GB
Mac OS X Lion 10.7.3
Before I kept it on Snow Lep. because that was the only way I could play Old game on the mac, I.e Diablo 2 and One.
But when I got into Diablo 3 beta, the old OS, the graphic is pretty bad especially for the ground lol it is black. So I updated back to Lion and everything work smooth. Depend on your connection too, but for me on medium setting it run smooth with 2 ppl, but I have to set it to LOW setting for 4 ppl, but I don't notice any diff when it is all low setting imo, so it is all good.
If you've got a MacBook Pro you've definitely got a better GPU than the Intel HD you've listed.
Mac's turn off their "powerful" GPU to save battery/heat when you're not gaming.
If you dig deeper into your tech specs (check the Apple website too), I think you'll find you're running an ATI 6xxx type video card, with probably 512-1GB of VRAM.
I run at 1920x1280 (1080p for you console players) and have all settings at high (except for shadows at medium).
Runs fine! There are some stutters, but that's the same Beta-stutters that everyone is reporting no matter the machine.
Loving it!
