Hi, this is probably a stupid question but i have to know lol! I just bought a macbook a few months ago and I'm still new to it. My roommate has one as well, although he's had his for a while. We use airport express for wireless internet for our apartment. Someone told me that when you use an airport express, whoever else is using it too can see what files you have on your computer, or they can see what websites you're currently looking at... is that true?? Because that's pretty creepy! If it is true, is there any way I can block him from seeing all the websites I go to and the files on my computer?? Sorry if this is a dumb question but I didn't know if it was true or not! Thank youu!
