Hello everyone. I'm Mike 50. I have an iMac G3-333, 160MB RAM, running OS9.1. The IE5 browser I'm using isn't supported any more at some of the websites I visit and is no longer upgradable. I'm considering installing two new 256MB memory cards from Memory Solutions so that I can install OS10.4 and use Safari, but have read at the Apple site that non-Apple upgrade cards will not work with Mac OS. Is this true? Is the 333 speed of this machine a hindrance to running Tiger? I'd also like to use GarageBand and Photoshop applications. Is my machine truly obsolete and should be replaced? Thanks.
