Apologies if this has been mentioned already (I could not see a way to search just the beta posts).
Description: Unity crashes Mac OS 10.13.6 after making changes to layout.
Steps to reproduce: I am not sure what conditions are required but it happens around once every 20 minutes of use, so I was assuming this is a common problem that others have reported and Unity is aware of. I just triggered it by moving the boundaries of two windows in the editor. I did get an error when opening Unity with my saved layout, which was about calling an End Layout function with no corresponding Begin Layout function. I didn’t save the error, and now it is not showing.
I have attached a screenshot of the layout I currently have in case it helps.
