I am running Houdini Indie on a iMac 2017 with retinal display, and even with setting it to high dpi, the icons are still too small. I have read that one can add the command export HOUDINI_ENABLE_RETINA=0 to the houdini.env file, but I do not see it anywhere on my Mac (and I have checked the user library preferences for this tile). Is there something I need to do to create the environmental file, so that I can add this line? I have tried opening the houdini terminal and typing in:
export HOUDINI_ENABLE_RETINA=0
houdini

but that opens the wrong version of houdini. I would like to set houdini to not use retinal display for all sessions. I would appreciate your advice. Thanks.

Creating an environmental file did not work, but what did was to select the Houdini Indie executable and right click to get properties. Then set to run in low resolution mode.
