Rhino 7 on mac crashes and logs me out of finder

rhino 7 on mac crashes when i try and set textures and logs me off finder.

any clues?

send a file and the textures you are using, steps to repeat the issue, and the report generated from running the systeminfo command in rhino to tech@mcneel.com and we’ll take a peek-
