Tamsin Slater, sorry but I am trying to figure out how this forum works. To answer your question I am using Vectorworks 12.5.3 on a mac mini with Snow Leopard.
Thanks Jim....very helpful! This is good news for me. I have two mac mini computers one with Snow Leopard and the other with High Sierra. Vectorworks 2011 would work on Snow Leopard.
I have been using Vectorworks 12.5.3 and have Vectorworks 2011 but wanted to know if there are any comparability issues before I try to install it. Any information on this subject would be very much appreciated. Thanks!
