Re: G4 not accepting OSX Hi All- I am rather new to this list, but I had similar problems installing panther on my home G4. After removing and playing with a number of options related to video cards and the processor, I found that removing all of the memory except one stick allowed the install to continue. It may be a memory issue or something odd in the install process (I can run with all of the sticks after the install with no problems). Good luck - Jeff Lewis
