Hi Masih,


I've had the same problem with my MacBook 13-inch late 2008 model running on OS X El Capitan.


There are many web links that suggest running on safe mode - this doesn't work as the laptop doesn't boot at all.


I took suggestion made my glendon1995 -


1. Hold Command + s while you power on the laptop

2. Type: /sgin/fsck -uw once you see root#

3. Type: chmod 775 /

4. Type: logout


This will take you to log in to your laptop - at this stage I suggest back up your device to a external hard drive so you save your contents in your laptop. Then once back up is complete, shut down the laptop and power on the laptop on Single User Mode again and follow the steps suggested on the link - http://osxdaily.com/2013/08/07/how-to-repair-a-mac-disk-with-fsck-from-single-us er-mode/


This has worked for me. I can't be sure if we have the same problem but worth a try I guess. I also found following link helpful:

Cheers. Good luck
