Hi, can anybody help me with my Mac(AGP Graphic) G4/ 80GB HD/ 960MB RAM/ OSX 10.4: When I start it up, the only thing I see is grey screen with the apple logo and rotating timer. I bought my Mac month ago. It was running with no problems.
What happened:
-I installed some freeware
-Changed DVD drive
-Upgraded RAM (512 up to 960MB)
When using iDVD applications, it got Kernel panic. After restarting it, only grey background with the apple logo (tiger design) appeared on the screen.
What I tried to do:
Shortcuts:
-Start up + Option (or C) → HD icon → Arrow = grey screen etc.
-Start up + Option + Command +P+R
I used my friends installation disc OSX 10.4:
-Start up + Option → HD apple test icon = doesnt work
-Start up + Option → HD install icon → Arrow → choice of the language → Alert: This software cannot be installed on this computer!
(I only can get into Installer)
In installer:
-Utilities → Disk utility → First Aid → Hard Disk → Verify disk = First Aid failed
There is a note:
keys out of order
The volume Hard Disk needs to be repaired
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair
Sorry, I am just a very beginner, so it might be a bit confusing.
If the only way is to erase Hard Disk, please give me a info how to do it.
Many thanks to everyone MAC FBU
