Hello everyone. I have recently upgraded the hard drive in my 2010 MBP, I upgraded it to a Segate 500GB, 7200RPM drive. By doing this I liked the idea of having a brand new hard drive with nothing on it. I installed Snow Leopard via the install disks and all that stuff. I also did a Time Machine restore. A month or so ago I followed these instructions(http://tiny.cc/wsxti) before I got my new hard drive. I found a ton of stuff in the Library>preferences step and the Library>Caches on programs that I no longer had, there were pieces of applications that have not been used in years! When I got my new drive in and did the restore it restored all of the preferences and caches on the stuff I no longer have, and had deleted. Do I need to completely reformat and erase everything on my external Time Machine drive to keep it from restoring all of the things I removed, and then have it do a fresh backup of my current Mac hard drive after I re-delete all the garbage off it again. Ideally I would like to have everything erased on my Time Machine and Mac hard drive except documents, photo's, music, and saved websites in Safari. I want it ALL gone, even settings and stuff like that...I can redo those. I don't need any applications saved either, I have all of the disks for those. How do I get this done? Sorry for the length, I tried to edit it down as little as I could while being informative. Also, I searched MacRumors and Google but couldn't find anything for this exact scenario. If you have a link for something other than "cleaning my hard drive" or "restoring my hard drive from time machine" or procedures for the current decade please post them. Thank you for your time!
