Hi! I have a dual processor G4 and recently installed Max OSX. All was going well until I decided to be clever and move all the files into my applications folder so it all looked nice and neat. Bad idea! The next time I turned on the computer lots of settings had been lost such as internet settings. So I re-installed OSX again. All seems fine, and it's still really quick, but I now have 2gb less memory. Anyone any ideas where it has gone? Do I need to defrag?
