My laptop crashed for no reason (after fixing 6 or more other issues yesterday) and when I turned it back on only the little corner light came on. I don't know what is wrong or why it crashed but it's driving me up the wall.
| 1. | Shut down your Mac. |
| 2. | Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4. |
| 3. | Turn on the computer. |
| 4. | Press and hold the Command-Option-P-R keys before the gray screen appears. |
| 5. | Hold the keys down until the computer restarts and you hear the startup sound for the second time. |
| 6. | Release the keys. |
If this fails to restart, then try booting in Safe Boot mode.
Safe boot
* shutdown
* start the Mac and *wait* for the startup chime to sound
* after the sound, press and hold down the shift key
* keep holding and *wait* until the grey Apple logo appears
* now release the shift key and just wait (it could take a few minutes)
* eventually the login screen appears with the words SAFE BOOT
Still not starting...
