I currently have a MacBook (1.83GHz C2D, 2GiB RAM, 60GB HDD) that I bought back around February/March this year. As my first Mac, I blundered my way through a lot of stuff, hacking at things to make them work how I like it, probably in the wrong way, so I want to do a clean format & install when I upgrade to Leopard, just in case there is anything bad that get's copied across if I do an 'upgrade'. What I want to know, is what I should do to cut the crap out of Leopard, because I want a nice, clean, small, stable install right off. The things I have done in Tiger so far include; turning off Spotlight turning off disk indexing deleting all the included apps & application data that I don't use (Garageband is several GBs on it's own!) deleting all of the printers except the one I own (another GB or more there) deleting all the languages I don't use deleting all the PPC code from everything turn off the Genie effect etc. I know already that I'll want to kill Time Machine straight off the bat, but there must be more things to get rid of?
