I'm ready to buy my very first Mac Laptop. I am not computer savvy or anything so I might come off as such a newb. Anyway, I'm going to purchase my mac online. I did a little research about the wifi for Mac and it confused me. Like I said I'm not very knowledgeable with computers. I have a Dell laptop now and it picks up my sisters internet connection. Now is it similar with the Mac laptop? Will it just pick up an internet connection that's within range? I hope I didn't confuse anyone else like I did myself.
