There are many years that i use CAT programs and I am very happy with them. But this year, sick and tired of Windows (bugs and problems almost everyday), I have changed to MAC (and it has been a very good choice). Now i use CATs with parallels, but everytime i have to load windows virtual machine (XP pro version), only for this, and so I do it rarely. CATs are the best programs on this type on the market and it is a pity that they are not on MAC. I know that is a hard job, but how many ppl do you think will stay on windows with the "8" version? I think that slowly slowly MAC will be more popular than windows, also if the price is higher (but the quality is much better).
However... Merry Christmas and Happy New Year !
