The OpenGL display window of VMD 1.9.1 (non-CUDA) is freezing immediately after loading a set of PDB coordinates in a fresh install of OS X 10.10

I’m using a late-2012 Mac Mini (8 Gb RAM, 2.5 GHz i5, Intel HD 4000 graphics). The spinning VMD logo freezes, and the molecule is not displayed. Here’s the console log (note that the program does not crash, it is just unusable):
