ok. so. im kinda anal about backing **** up. that said... im getting a MBP for school blah blah blah yadda yadda yadda i need a program that will allow me to automatically sync files between both my macs. (preferably wirelessly) id like the notes i take in class on the mbp to sync with the imac when i get home. Id like my picture folders, design work folders, and documents folders to be in sync on both computers whenever im home. if i add new pictures on the mbp, take new notes, or work on a .psd file. I want them available on the imac without me having to manually bring them over and vice versa. i just need a way for the folders to sync whenever im home. that way when i do a back up on my imac, it also has a back up of the folders on the mbp. and for free? or very cheap? or am i just asking for way too much?
