Version 1.3 does not work on any of my Macs.

I have tried now on several Mac computers:
Mac Pro 5.1 with OSX 10.13.6 , Max Pro 6.1 with OSX 10.14.6, and on my Macbook 1019 with Catalina, where SH3D 6.3 won't even start.
SH3D asks for legacy Java SE6 runtime – which of course cannot be installed because a newer version is already installed.

What is your working config for OSX?
