It runs okay for me - the only place I really notice the difference between it and my higher powered Mac is during rendering - rendering takes considerably longer. But setting up stuff and loading stuff from the library is only a little sluggish. Oh saving and loading scenes is slower too. I'm sure it would not be able to render as complex a scene as a PowerMac or high-end iMac but I haven't run into that yet since I do fairly simple scenes. On the other hand, Hexagon does not run properly on my Mac Mini and I've given up trying to use it on that Mac.
