Can owner PC CE + Missing Link get the Mac edition for free?

[BHTrix]

I've send Eidos several e-mails which are not being replied too, very unprofessional if you ask me.
The thing is, I own an iMac 27". Being the fan I am of the deus ex series I pre-ordered the PC CE and The Missing Link DLC the moment it was released. Which basically results in an ultimate edition. I installed windows on my system and had a blast playing the game.

However a Mac version is out there currently, and I'd like to replay the game. However I'd prefer to remain in my OSX environment.
Now usually when I buy a game and I spend about 90 bucks (I really like CE's) I get a mac version as well.
Hell, even if I spend 20 bucks I usually get a mac version as well (if it exists).

And well, let's be fair, I own the game.

So my question is, do I really need to cough up another 40 bucks just so I can play the OSX version?

Kind Regards,
Paul
