I have an older G4 with OS 10.4. something. I never have had any trouble from it. I recently updated from the Apple site. Now the computer won't boot. All I get is a black screen with text code. I have tried all the following with no success.
1.) Reboot the Computer. - Simple, I know.... This didn't work. Won't boot.
2.) Resetting the PRAM: When booting, hold down Command-Option-P-R and wait for the triple startup chimes.
3.) File System Check - When booting up your computer hold down the Apple Key & the S key and it will boot into single user mode. When the text is done loading on the screen type in /sbin/fsck -f and hit enter.
When that is done if it fixed things then do the check again to make sure it is cleared
When finished with that type in exit and it will start the computer in normal mode
4.) Reset Nonvolatile Firmware - When booting, hold down Command-Option-O-F and wait for the command prompt. Type "reset-nvram" and hit enter.
I can't use the cd that came with the computer to reboot. I don't have the original disk. Even if I found it I can't get the disk drive to open.
I also tried this: You could also reset everything else if you wish.
Start up holding Command, Option, O and F.
When the text has loaded type the following:
reset-nvram then press return
set-defaults then press return
reset-all then press return
It will boot back to your OS then
After all this, I still can't get it to successfully boot up. All I get is a black screen with text code and a message that tells me to restart.
Anyone have other ideas???????
