Hey guys (and ladies), I bought my iBook G4 about a year ago. Since then, I find that the performance has slowed quite a bit. I thought Macs weren't supposed to slow down and die over time like all the PCs I've had before it, but this thing is really starting to get sluggish. I have the base 512 megs of ram. So my question is, how do I improve the performance and speed of my iBook? Do I need to "defragment the hard drive" or re-install the operating system (things I always did with slow P.O.S. PCs in the past), or do I simply need more ram? FYI, I don't think my hard drive is the issue. I've got a 60 gig hard drvie with 18 gigs left. Thanks a million for any advice you may have, I really appreciate it.
