Something similar happened to me last night, and I doubt it was
overheating.  Mesh Viewer.

Bizarro graphics and then a total OS X lock up.  Had to finally cycle power.

next try, similar, but before the lockup I got into preferences and changed
graphics from High to Med.  After that, things worked ok.

if it happens again, I will try to get better data.
