Hi there. I have recently upgraded my imac g4's ram from 256mb to 512mb and i can say that it is much faster that it used to be. I was told to download TenFourFox and Mactubes. Mactubes runs ok when using quicktime but TenFourFox is really slow. Is there anything that i could do to make my g4 faster? And is there any good free applications that i could download? My mac is a g4 PPC, 700mhz, 512mb ram. Thanks!
