After a crash my G4 800MHz boots to Darwin only. I've tried to install OSX (10.3.9) but, is says I have a newer version of software on HD. Then I tried to install 10.4 but, my computer says it won't accept bundled software (?) I've tried disc utlity and repaired permission errors and HD errors to no avail. My goal is to simply remove files to a temporary safe location (dvd, external drive ,etc), and to refomat HD. Please help Thanks, Charles ( Novice)
