Ois: The OP here is not a whiner, the question may of been asked several times, but a whine comes across different.
I don't know about software forums, I do experience many people complaining at work on this: MAC software not running on a PC, MAC software not running on an old version (PPC era?) of OSX and the same for Windows users (actual quote: This software is only 15-20 years old, why should I buy the XP-Vista version when it worked on the '386 windows').
There's a huge difference between an ignorant user complaining and an informed user complaining: the ignorant user complains because s/he doesn't know any better, the informed user complains
despite knowing better. This is why an informed user comes off as whining, while the ignorant user might just come off as foolish.
This is obviously a case of a sufficiently informed user who knows the difference between a Mac and PC, knows that this is a website for PC games, knows that those games are not compatible with their OS of choice and despite knowing all that, still chose to post something that ends up reading like whining.
