Just to add my thoughts in here briefly. I've not noticed a crash in 1.0 from QA all the way through to release that wasn't already noted (e.g. the annoying symmetry crash...) But I run on a very old PC so gfx settings tend to be low-medium, and resolution not over 1920x1080. From my experience, shaders/anti-aliasing are known to cause a few graphical glitches particularly on OS X, so if you are getting very frequent crashes to the point of it being unplayable, I'd recommend making sure anti-aliasing is off, and PPFX is off (it should be by default, because it's known not to work terribly well on OS X) Also, a fresh install seems to be helping some people, which would tally up with what I see, as I regularly cleared out and re-installed during testing, and I'm not seeing any of these issues
