To all, Just bought a G3 700mhz and a G4 tower 450mhz. They aren't terribly slow but slow enough to where I want to clean them up a little bit. I have the free version on cocktail and XSlimmer (which only allows up to 50mb of defrag capabilities). I know that Macs "never need to be defragged" but I am just wondering if there are free tools comparable to XSlimmer? Im running 10.4.11 so would running a software update help out at all? Just wondering, thanks to anyone who answers.
