Okay guys, I have owned a Macbook for like an hour, so work with me. If I'm trying to save a file to my computer, for example an image file, where do I save it to? Macintosh HD? That is my SSD, right? Then what is "Lisa's Macbook Air" (I'm Lisa, and that's the "name" of the computer). What am I doing by saving files there?? And in which one are my photos, documents, etc?? Also, if I want to forward an email with an attachment, will that file stay attached when I click forward? I tried to do that, but I don't see where the attached files are. Thank you so much!
