Hey, I have a Power mac G4 MDD, yesterday i was trying to install Leopard on it, it kept on saying things like "Install failed and couldn't verify "Essentials" package" and a bunch of others, i searched it up and some other forum told me to reseat my ram in different places and see how it goes, that didn't work, it kept on coming up with the same messages. So then i gave up on it for a day and now it has no chime, and no display. I have tried another AGP card, resat the ram in different positions, tried ram from another working system, and booted with no drives plugged in. Help is much appreciated. --Bruce
It seems the Mac was nearly failing. It probably needs a new Mobo or CPUs.
Disassemble thoroughly using alcohol and compressed air. Clean all components with microfiber cloths and cotton swabs. Examine cables closely; likely need to swap out the HDD and optical drives for compatible models. This should be the most effective approach.
I conducted some tests and discovered a functional G4 in my dad's garage. I replaced the CPU, and it seems the motherboard might be faulty. Appreciate your support — Bruce
