I assume by YOU you refer to GHL, well I hope so
This is something that has been covered in the support forum. To develop Mac software would cost in excess of $50,000, would GHL get $50,000 of sales for this development when VM works just as well and costs nothing? The answer is of course not. Mac still remains the underdog of global user base, whether that changes of course time will tell.
Windows 8 is the bug bare of many software company not just GHL, its an uphill battle, GHL do not hold the magic wand to the cures of the issues that come with Win 8, its known to be an issue with all sorts of softwares, so sadly GHL are in the same boat as many others with this issue.
I would love to give you a more positive answer, but GHL cant spend out $50,000 on something like that (You dont see Ecotech with Mac support) and we have to wait I guess for Microsoft to wake up and smell the roses.
