hello Macrumors.com we have 2003 macpro tower running 10.4.11 2008 17" macbookpro running lion 2010 airpot extreme 2011 13" macbook air 2011 thunderbolt display. 2011 iphone 4s 2011 3tb g drive 2011 magic mouse we do have a bunch of gadgets but i am not the most tech savvy person What are my options to network my computers for the home. I work from home mostly on the macbookair. I do art and music and movie projects on the 17" macbook pro. Right now I have the 2003 macpro as a media center downloading movies and music and we watch it off this computer. I have opened the file sharing option on the computer with the movies so the other computers can watch but not sure if this is the best option. my question are What options are there for connecting multiple devices? If I have all my music on one computer how do play the music using my other iTunes? Can I listen to my music in iTunes if its on a external hard drive? If I am in my home office do I need to use iCloud to sync my calendars and contacts? Is there a way to have my magic mouse run my macbook air and my mac book pro?? is there a way to plug my 17" 2008 macbook pro into the thunderbolt display So many options not quite sure how to set up the network? Thank you much for taking the time David ---------- anyone? will i ever gert any input?
