I have a G4 mac, it's not panther its jaguar, but i need some help and im hoping somebody will know something! I havnt had any problems with it until now. When i turned it on the other day it started up, got to the loading screen (grey with a clock and apple logo) and then didnt change. Ive tried all sorts but it just sticks at the loading screen and doesent boot up fully. I've been staring at a grey screen with a clock ticking round and round for over a week now. I need the computer for my work so i really need to sort this, does anybody know whats happening with my mac? I'm getting worried
