My son's MacBook won't start up. All he gets is a blank screen with a gray apple and a gray spinning wheel.
Tried the following
Press power button and hold 'Shift' key. Same result, gray spinning wheel no start up.
Press power button and hold 'X' key. Same result, gray spinning wheel no start up.
Press the control key, the command key, and the power button
simultaneously and hold for three seconds to try to restart the
computer. Same result, gray spinning wheel no start up.
After pressing the power button, hold down these keys simultaneously:
Command-Option-P-R, until you hear the startup chime at least one
additional time after the initial startup chime. Same result, gray spinning wheel no start up.
If you have your Mac OS X Install disc, insert it into the drive.
Restart the computer and hold down "C" while booting.
Choose your language.
Select "Disk Utility" from the "Utilities" in the menu bar.
Select your Macbook's hard drive in the left sidebar.
Click the "First Aid" tab thats along the top of the viewer window.
Click "Verify Disk" (not verify disk permissions)
If this shows errors click "Repair Disk"
Once completed close the Disk Utility window.
Restart the computer.
If this fails to fix it as well then your next option would most likely be recovering your files from the macbook either by booting into target disk mode (hold down T at startup) and transferring them via a firewire cable, or removing the hard drive and hooking it up to another Mac to get the files. Then do a clean install of Mac OS X using your installation discs.
