I use an old copy of Vectorworks on My MAcPro 5.1. My current system is 10.12.6 Sierra. The Mac Pro has an interesting setup. I can put 4 different Hard drives in a Mac Pro, and because of that I can run different versions of the MAC OS. When I need to do drawings and I pull up one of my other operating systems on a different hard drive and boot from that system which then runs the different software . To do this you just need to create a boot disk on the mac and match the Vectorworks software to the OS you have
