Is it okay to run Photoshop CS5 on a Macbook?

My friend is going to let me buy his Photoshop but I’ve heard I can’t or shouldn’t run photoshop on a Macbook. Here are some of my Macbook’s specs. Is it okay to run? Will it affect my computer?

Also i’m not a professional photographer or anything just edit couple of pictures and sometimes make graphics for my blog posts. Just general use.
