Hi, I don't know if I should build everything from scratch or use my Time Machine backup to rebuild my old system on my new 24" iMac? I'm currently running the latest version of Leopard (v10.5.4) on my iMac G5 (see my signature for specs!), and I'm using Time Machine with an external firewire harddrive for my backups! I've only recently installed Leopard, about 5 weeks ago, and keep a very maintained and clean system running. Is switching from PowerPC to Intel going to cause a problem (drivers, prefernces, apps, etc.)? I have never used one of those stripping utilities to remove the Intel part of applications! They should still all be "universal"!!! Could there be any other problems? Furthermore, I'm going to use a bigger, 750 GB HD with the new machine, instead of the old 400 GB (75% used!). I'm migrating from a 20" iMac (PPC) to a new 24" Intel-iMac, which is going to arrive next week. What would you recommend. Any testimonials? Thanks.
