Hello John,

Thank you for your fast reply. My apologies for being a bit vague
in my last mail:

Both the 2012 and the 2014 Mac run the same MacOS. On the old
machine the cube files still load perfectly and everything else works
as expected. On the new machine the OpenGL window freezes.
This is true for both for 1.9.2. and 1.9.1.

The cube files were generated with different codes (i.e. MultiWFN,
nciplot and such) none of them works. The new Mac has 16GB of
memory and about 6 are free. It uses and Intel Iris Pro card with
1,5 GB dedicated RAM.

I have tried everything now and the only thing that does work on the
new machine is opening a pdb file over the net. Everything else fails.
I have been using Macs for a long time and I feel rather stupid now.
I am grateful for any adviceā€¦
