Hi, I want to completely re-install Mac OS X on my Mac Pro for several reasons: The system is old. I started it with 10.4.1 and upgraded it to 10.5, then to 10.6. On the way there, the system has been moved from an old Mac Pro to a new one. The system has seen a lot of playing around with, tons of installs (incl. drivers) and by now is simply a grown mess with a lot of problems that I can't seem to fix nor want to fix. So - I want a fresh start. And I need some help planing this. Back in the days of 10.5 you had the option to "archive and install", which would simply move the old system to a folder and install a baby fresh Mac OS X on the system. You could then go ahead and move things like applications, the user library and what not from the archived location back to the new install, one by one, piece by piece, in a very controlled fashion. With 10.6 that option is no longer available. So the question is: How do I erase and install Mac OS X 10.6 while retaining my old stuff? I know how to do the fresh install, the point is more like how do I keep and import old stuff... How good is the migration assistant? I figure you can use it to import old stuff from a time machine backup. In the end, I want a fresh install and be able to import things like preferences/library for certain applications (that I don't want to rebuild from scratch, like a huge Plex Media Center install) - without reimporting things that are causing problems on the current install. Any ideas, help.... much appreciated! Thanks!
