Question about playing on laptop??

I have a Mac book Pro. I downloaded Steam. Bought the game. But was so eager to play, I didn’t pay attention.

“Only for Windows”

Now I gotta buy a laptop (I think) because I just want to play this game I used to play as a kid.

My question is do I have to buy a “gaming laptop” or a regular laptop?

I’m sure you can tell by now that I don’t know the first thing about gaming on computers
