I'm about to acquire my sister's iBook G3 500 MHz for a project I'm doing which requires iWork '05 and Photoshop Elements 2.0. It just might be me, but after using my iMac Core Duo, the iBook appears to be lacking power. It has 384 MB of RAM. I'm wondering what I can/should do to optimize the machine. Here's my list of things I'm thinking about trying: - Clean Install: The HD is filled with my sister's stuff, so it's given I need to empty it before I do my project. Nearly 9 GB of crap! I figure a more empty HD would be nice. And I'm sure the system is filled with tons of things I don't need. - Downgrade to Panther: I'm wondering if Tiger's system requirements are accurate and is only being deadweight for the iBook. - Install a new chip of RAM. I already added an extra 256 to the existing 128. I wouldn't want to buy another chip to replace that. Any other suggestions?
