I've been looking for ways to speed up the Emac without overclocking.. since I have no idea how to overclock. I have OSX 10.4.11, and I have been trying to get OSX Panther to install recently because Tiger is a little slow. It just won't boot the CD. I don't know why. The OSX Tiger CD was able to boot, but not Panther, even though the Emac was made before Panther. (I mention this because I hear that you cant install an OS older than the Mac) Maybe the Emac is slightly newer than the Panther discs I've been using. I am currently running Safari on my Emac, since Firefox is slow. It's a shame, since Firefox is my favorite web browser. My Emac is running on 768 MB of RAM.. I would love to speed up this computer. I'm going to get some RAM soon, but I have some doubt that this will help much.
