I was at home on winter break and had my computer set up so I could connect to the internet with my XBox through my macbook. I got back to school yesterday and didn't change the settings back and I had sharing enabled. I have all my passwords and usernames in a document in my documents folder, however its not named passwords or anything obvious. I'm just wondering if I had these settings set up: could someone have gotten into my computer over our network (I live in an apartment complex that provides internet) and gone through my stuff? I left the computer open for awhile with airport on (forgot to turn that off when I got here too) not using it, but not connected to any wireless router. Or was the sharing enabled only if you were connected to my computer using an ethernet cable? Lets say I was connected to someone's wireless router could they have gone through my stuff? (pretty sure I wasn't but not 100% sure) I don't want to have to go change all my passwords if I don't have to, it'll take awhile to change them all.
