Good question. My MacBook Pro with the Nvidia graphics card is now only used with a scanner because it’s now a slow thing that can no longer be upgraded.
Soooo, I tried updating the OS to 11.2.1 Big Sur and it still has the same problem. I get the spinny Rainbow and have to force quit. Seems to happen if i move around a lot…
That is not a crash, to my way of thinking. SketchUp might be stuck in an “infinite loop” (which would be very bad, a bug somewhere), or it might be making progress on an operation that takes a long time. How long do you wait before doing a Force Quit?
Can you briefly describe the SketchUp model (e.g., how many edges and faces are in the model, according to the Model Info panel), and are profiles and/or shadows enabled in the active style? By “move around” do you mean pan and orbit the camera?
OK, that’s a fairly long time thanks for the specifics. Perhaps an extension is trying to do something? You might try using the Extension Manager window to disable all extensions, quit and restart SketchUp, and see if the behavior has changed.
Or try a simpler model (one with just a few dozen edges and faces). Your model with 100K edges is not what I would consider huge, but if Profiles and/or Shadows are enabled in the current style, it might be triggering something wrong.
