Have successfully installed pymol Version 1.8.4.0 (via homebrew) from source on several macs (El Capitan), but on a new Sierra-based Mac Mini (Intel Iris 1536 MB graphics card, 2.6 GHz Intel Core i5 running Sierra 10.12.4) it constantly crashes whether launched from Terminal or Xquartz. Starting from Terminal using either ">pymol " or " >pymol -M "I get the same errors: Screen below:
uos$ pymol -M
