I have an iBook details are as follows: Machine Name: iBook G4 Machine Model: PowerBook6,5 CPU Type: PowerPC G4 (1.2) Number Of CPUs: 1 CPU Speed: 1.33 GHz L2 Cache (per CPU): 512 KB Memory: 512 MB Bus Speed: 133 MHz Boot ROM Version: 4.8.7f1 Serial Number: 4H51907SS85 It is operating very sluggishly, with the spinning ball operating a high percentage of the time. I am planning to install additional memory, 1.0GB (1024MB) PC2700 DDR SODIMM 200 Pin Memory. Is there any utility or program out there which I could use to make my computer operate faster, with no intervention of the spinning ball All help and advice appreciated.
