It might be too late past the development stage to ask this, but is there any way we can convince GDS to make a Mac port? I'm in a pool of people who have upgraded their Macs this year only to find TEW2020 is not able to run, even through Wine or CrossOver. We're patiently waiting for Parallels to release their latest app version but it will cost us more than double the cost of TEW2020.
As such, if a Mac port was released at a higher price than the Windows port, guaranteeing native support, I'd be happy to spend that extra bit of cash to support GDS in doing so and I'm sure many others would be, too.
