  • Ensure both your OS and drivers are fully up-to-date (and use official GPU drivers, not those provided by windows or tablet/laptop maker or open source ones in linux distributions).
  • Try to start Blender in factory settings (--factory-startup commandline option) (this will ensure whether this is a userpref or addon issue or not).
  • Try to tweak your GPU driver settings (e.g. try different values between 'performance' and 'quality' if you have such slider, etc.).
  • Try to start in software OpenGL mode (use the blender-softwaregl distributed with official blender, will be slow, but will show whether this is a driver issue or not).

Thank you. Did this and it still crashes. Don't know how to open in OpenGL mode. Can you describe how?

As said above, you should have a blender-softwaregl script next to blender executable, that will launch it with software OGL rendering.

Also, please try to run Blender from the command line with --debug-gpu option and attach as text file here any error printed out in the console (do not paste it directly in comment).

Can't find any OpenGl script inside blender app. Nor do I find any information on how to on Google. Here is the text file output after --debug-gpu command.

@Arto Kitula (akitula) don’t we have a software-gl script in OSX builds, like we do for linux ones? Anyway, from the log it does looks like a GPU/driver issue, guess you are the best guy to handle that report…

@Omid (Khanman) Could you give your system info also. (which mac do you have?)

More than a week without reply or activity. Due to the policy of the tracker archiving for until required info/data are provided.
