This chart is very helpful in my considering whether to invest in a new Mac or not and all of it's associated costs. I am wondering why all versions of Vectorworks is supported by Windows 10, but only the two latest versions of VW for mac (2019, 2020) will work with Catalina. I have VW 2018 - so it looks like I will be keeping my old computer and avoid upgrading to Catalina. :(
