Hello. I have several specific questions and have been going in circles researching and trying to find the best solution(s). Here's the deal: I have a 2.0 ghz G5 iMac that has a nearly full hard drive. It has mainly been used as my primary work and occasional home computer. Recently, I was given a 2 ghz intel core duo MacBook pro from my employer that has now become my primary machine. In addition, I have two external hard drives that will be thrown into the mix as well. The first is a 500 gb drive that only has my digitized cd collection on it. The second is a 250 gb drive that serves as an archive of client files. Lastly, I have a treo that is synced with the imac with the markzware missing sync software. This is where you come in: 1) I need to zero out the iMac drive. It has had a few issues and it would just be good to have a clean slate for my family to work with. I have music files on it that need to be moved to my "music" ext. hard drive. I have personal items (iphoto, imovie, quicken, treo info, keychain, etc.) that I need to make sure I can save and use after the clean install or move to the MacBook Pro. In addition, there are tons of other files that I may not want but need to make sure they are available at some point if they are needed. What is the best way to prep for and complete this? 2) What is the best way to streamline the reinstall process after the clean os install? Should I try to collect all the app installers i've purchased online as dmgs and burn to a dvd or should I just download again from the manufacturer site? 3) When this is all said and done, I'd like itunes to be able to have all of my music from the external drive available to play. Also, if I rip more cds or make purchases from itunes, I'd like them to go directly to the ext. drive automatically without holding down keys every time my family launches itunes. How do I do this? 4) I keep a small digital camera with me while I'm away for work and my family has one as well. In addition, I occasionally take "notes" pictures with my treo that backs up to iphoto when I sync. Since I download my camera to iphoto on the MacBook Pro and the treo and my family download to the iphoto on the iMac, we have pictures in multiple places. What is the best way to maintain a "master" location for iphotos? Is there a way? 5) Is there a site that can explain how to set up a secure wireless network with an airport express and how to share access to computers and drives on that network. Thanks in advance for your much needed help. Cheers.
