So I decided to go to Tiger because the requirements are WAY lower than Leopard. I learned my Memorex DVDs don't work on PowerBooks as well during the process. I went the USB route, LightBulbFan guided me through the entire process. After 30 minutes of hair pulling, Tiger booted up! The performance of Tiger is amazing. When I was on Leopard, I got G4 Fan Control(0.5) but the entire UI would slide when you toggled the settings making it unusable. Now that I am on Tiger, I was hoping G4FC would work but it won't open. It pops up in the dashboard and then disappears... Anyone know what the issue is? or any Alternatives I can use? Thanks!
