Need t change partition

I think i gave Windows too much space on that partition. Is there a way that i can give Mac a little more, and give Windows less, without having to wipe the entire computer?

Yeah. You can restore both partions to one using the boot camp assistant and then run boot camp assistant again to start from scratch.

You'll lose the windows side of things, but your Mac will be fine.

no, as far as I know you can't do it with the software that comes with the computer
I think there may be some third-party software out there that may let you do this-but more than likely you would have to pay for it

Aptmunich, do you know where i would have to go in Bootcamp to change it?

Sure, go to
"Applications> Utilities> Boot camp assistant"

and launch the assistant. Then select the 3rd option:



Then restart when it's all done and launch the assistant again, but this time choose the second option.
It is recommend that you back up your documents before doing this though - you're reformatting a "live" disk with beta software- there is always a possibility something could go wrong!
