I have had my Intel Mini, 1.83ghz 1gb ram running 10.5 for a couple years or so now and for at least the first year, it was as fast as I needed it to be for normal things, safari, itunes, quicktime and other random useful apps but not to high performance apps, but for a while now it has started to lag quite a bit just having, itunes, safari and a few menu bar apps open, (Caffeine, Synergy, Maclock, airmouse, remote tap, and evernote) I could explain more if needed but I think if the right person is reading this they will know whats going on and how to fix it? Also I have tried to keep my hard drive fairly tidy, with appcleaner and other maintenance apps, so I dont think its just that I've just over junked my mac, are the regular apps just to getting to processor dependent? I dont think I really should have to upgrade just yet, or would 10.6 make a big difference. before this mac I used a Power PC G4 and it went through the same problems but it was almost 10 years old, I dont want my mini to go in the closet just yet. Can anyone help me save it?
