Painter 2021 & MacOS High Sierra 10.13.6

Has anyone been using this version of Painter and High Sierra?

I had recently purchased Painter 2021 and then realized that it required OS 10.14 when I use 10.13.6--and I don't want to upgrade the OS unless it becomes that I must. 

  • I upgraded to Big Sur, then found my Painter 2020 was incompatible. So I upgraded to P2021, only to find that my current Mac Mini 2018 was struggling. So I had to get a Mini M1. An expensive exercise. This incompatibility should have been clearly signalled by Corel.
