I know there are a lot of threads relating to what I'm going to ask but the more I read, the more confused I become. Please offer me some suggestions. I have a MacBook Pro (2007) and a very recently purchased iMac desktop (2013). All of my data (folders, contacts, calendars, programs, apps, etc.) are on my MacBook Pro. I'm slowly transferring all of my data onto my iMac as I want it to be my main computer. I want to use my MacBook Pro only when I'm travelling. So here's my problem: I want to sync EVERYTHING, and I mean, EVERYTHING on both the MacBook Pro and iMac. Anytime I edit a file/folder/contact/calendar/etc. on one, I want the other automatically updated without me having to do anything and vice versa. I don't know how I should do this. So here's my question: How shall I go about in doing this? ChronoSync? OS X server? Another solution? If it helps for clarification, I have an iPhone 4, iPad (3rd generation), Apple TV, Time Capsule (2nd generation), many other external hard drives. My dad also has a MacBook Pro (2011). Syncing between all these devices with my MacBook Pro and iMac would be nice as well. Please help me out, thanks!
