Hi, all. I've had my iMac for over a year now and planned on upgrading to Leopard, but just can't do it right now. I do have alot of garbage on here and would really like to just do a fresh install of the OS. I got the trial version of SuperDuper today and have an 80Gb External Hard Drive that I can back up to. So, can I just back up to that, reinstall the OS and then go find what I need as far as bookmarks, program settings, e-mail, etc...? I want to reinstall my programs as well, Photoshop has been running pretty slow and maybe it's the former PC user in me that makes me think this way, but I'm hoping that a clean install of the OS and only the applications I'm using will help it run better. Thoughts? Suggestions? Will I have everything I need if I just back up the whole drive to the Externa.? Thanks!
