“I pointed out that the Mac is based on the linux core”
That is incorrect! It’s a Unix core. That’s about all both share.
Afaik OSX is a BSD derivative. However, the familiarity would be close enough to port software realistically. Unfortunately the core does not matter in this respect as it is the graphics which cause trouble. And there we are looking at X-Windows versus Aqua. Worlds apart… unfortunately…

PS:And yes, the licensing and key issue in Zbrush is so annoying that, if there would be an alternative product, I will use that just to get rid of that machine dependency. I don’t need another thing to worry about when my system blows up. I already have a zoo of apps with each having a more or less questionable way of clinging to the hardware. But we all have to thank the asshats who copy software and use it commercially for this. Kid’s copying stuff and playing around with it won’t buy the software anyways.
