Too many crashes

[colin]

Check this post I made in July:

Returning to SketchUp stops inferencing from working, can't switch tools, crash soon after

@TheOnlyAaron asked me if a particular thing he was seeing was a known problem in 2024. It wasn’t a known problem, but I soon worked out what was really going on. The real issue would affect all versions of SketchUp that are running on a macOS later than Monterey. I will explain… Here are steps you can do in macOS Monterey, and get away with it: In any version of SketchUp, right-click somewhere in the document, to see a contextual menu. Single-click on the window of a background application. …

You may be hitting the combination that leads to the issue. Next time it happens try left-clicking to go to Finder, then left-click back into SketchUp, see if that fixes things.
