I've searched both Macrumors and the web in general looking for a step-by-step way to do this but still don't understand how to share files between my sister's new MacBook and my MBP...I've enabled the Personal File Sharing service in System Preferences, as well as AppleTalk in the network settings. When I go to Network > My Network I see my sister's MB's name (the new one I gave it as well as the old default name as well, this seems odd). When I try to connect I'm prompted for a user name (already filled in with my name) and password. Do I have to set up some kind of an account on my sister's MB to connect to it? Sorry for being so clueless on this, I've managed to figure out almost everything Mac on my own but this is really confusing me... Ironically I was able to connect to my mom's PC under Network > (Her PC's Workgroup Name) without any trouble or a second thought; I didn't even have to enter a password. Thanks in advance for any help!
