I gave my parents my old iBook G4 and it runs 10.5 Anyway I noticed the HDD is down to 10GB left out of 28GB or whatever it is. And it seems like the thing is just so slow. Safari just clocks and times out and quits. Everything else just seem unusually slow. Should i revert back to 10.4? Or is there something else I can look at to help the old G4 work a tad faster. Thoughts?
