Hello I currently have a late 2007 macbook that I recently upgraded to 4 gb ram and 250gb HDD. It is great and works perfectly. I am planning to now get a mac desktop to be kind of like a central hub and be my main storage center. So I am eyeing a white Imac 5G intel core2duo. But it may only have 250 gb HDD. I would like at least 500 gb so i would get whatever size and install the drive per these instructions http://manuals.info.apple.com/en/imacG5_20inch_harddrive.pdf Ok now my question. I would still use my macbook the most but I want the Imac to mirror my macbook (until the 250gb runs out). So if i rip 10 songs on my macbook is there a way that my Imac can copy it or mirror the macbook? I initally would have to clone my new drive and put it in my Imac like i did when i upgraded the macbook i assume but after that going forward is there a way or a program that will keep them identical (without manually moving stuff each time)? Thanks!
