I Installed Sketchup 2015 on Yosemite and it does seem to crash less. Podium works crashing less as well. Will re-install Vray 2.0 to test if it runs ok without crashing.

Hi John, Did you say yosemite and Sketchup 2015 don't have the same issues??? I am have te same problems as Kathryn. Do you thing i should upgrade to Su 2015. Anyone??
