After a month of no issues using Vectorworks 2019 on Macbook Pro with Mohave OS, today I'm not able to even draw a simple polyline without getting stuck with the spinning beachball of death, and have to do a hard shutdown to exit. I'm using the 2019 SP2 version of VW (Build 463397); Mohave has just been updated to 10.14.3. What to do?
