Mac development kit?

[death_himself]

Okay I asked this in the help forum but on closer inspection I realised it would've been more appropriate to post it ere, so apologies for posting it twice. Well anyway I'll be honest, I can't program, I can't script, I've tried to learn and it really isn't my thing. I do however like to learn about game creation kits and so forth, now I read somewhere that there is one for the PC (I'm new to the scene, don't laugh) but as you've prolly guessed I have a Mac, now I've searched around and haven't found anything so I figured this I should ask, just in case anyone knows anything. Would appreciate any help at all. Thanx. sorry bout the smiley, just it reminds me of the first game I bought.
