...iMac 7oo Mhz G3. http://docs.info.apple.com/article.html?artnum=120048 http://docs.info.apple.com/article.html?artnum=86117 I read about a bunch of problems people have had with OSX on imac g3's if they did not have firmware 4.1.9. The screen goes black etc. My (new to me) G3 has 4.1.7f4 (off the top of my head) but IS running OSX The latest update. But I figured what the hell, why not update the firmware to 4.1.9, and the power management update. It will not allow me to update because OS9 classic is not on my hard drive. Since my machine was shipped to me used, I have no disc(s) for the OS. It seems that the version on my iMac is for an iBook perhaps????....BUT it does work fine. I know if it works don't fix it, I was just wondering what my options were. The firmware update is supposed to speed things up a bit with OSX. How can I update, and is it worth it? Thanks.
