I am using Vectorworks 2018 (english version) with Macbook Pro 2017 with High Sierra. I could update to Mojave, when I get confirmation that Vectorworks 2018 works without problems with Mojave. Can you/somebody confirm that combination of VW2018 with Mojave 10.14.3 works comparable stable to VW2018 with High Sierra 10.13.6?
I can only put together what I see in the forum. The feedback for VW 2019 SP2 is unfortunately not in this direction, therefore I would not expect that the situation is any better in VW 2018 SP6, which is supposed to have the same level of support for Mojave.
