Hello I recently purchased new mbp 13" I used to be a PC guy but now I'm using mac. Yes, I'm lost all the time however trying to get used to my mbp. I'm trying to activate network with other computers at my house. I have no idea how to do that and I've been searching for it, please help! Isn't the network ball supposed to be blue or something? because mine is gray but it is connected to internet... I just can't see other computer's names at my house The other computers are all PC.
