I was wondering if anyone could help me with these questions about Mountain Lion (I currently have Snow Leopard and purposely skipped Lion. However, Mountain Lion looks more polished, so I will upgrade). What exactly is Back To My Mac in iCloud? Does that mean I can access all my Macs files/Screen-share from someone elses Mac? Does Mountain Lion dump memory for open apps if they are not the active window? (If I have Safari open in the background, and I do a bunch of RAM intensive things in FCPX, if I go to Safari will it have to reload the pages?) If you turn off application restoring (via Terminal), does OS X still restore the windows after a restart (via the checkbox)? Does Safari have a home button? I would appreciate anyone helps. Thanks in advance!
