Anyone else who is using sketchup on mac, are you having some lagging issues? With mine, about every 10-15 minutes, everything stops working and the rainbow wheel appears. It takes about 3-5 minutes to work again, but is there a way to prevent this?
Is Preferences > General > AutoSave on ?
You can kill it during this time, and Apple will write out a spin dump, which you could analyze, but not easy to pinpoint. You’re going to have to experiment with a number of things (Unless you’re really into debugging tools):
Is it always the same model?
What happens intermittently on my system. Autosave? Extensions doing work?
Keep Activity Monitor.app open and see if anything weird is happening at this time?
