Then boot into Single User Mode and run fsck.
1. Power on the Mac and immediately press and hold both the command-s keys simultaneously until the Mac boots to the command line (Single user mode).
2. At the command line type the following:
then press return
fsck will eventually return with a message. If it ran with no problems then the message should look like this:
The volume (nameofvolume) appears to be OK
If fsck came back with errors then it may look similar to this:
*** FILE SYSTEM WAS MODIFIED ***
In the above case with errors you will want to run fsck just as you did the first time until it comes back with the ok message listed above.
Once fsck comes back with the ok message then try the following command:
diskutil repairPermissions /
Then press return
To continue booting into OSX type:
then press return.
some update may alter permissions but not mess up the HD. FSCK is the equivalent of CHKDSK in windows. If you have exhausted everything and to no avail its still not working. Call Apple care and have them send you a disc. Just because you lost it does not mean you don't need to get one. The OS X install disc(grey one) are extremely helpful in all instances. It also has hardware test. So go get one. Once you do perform the following:
1. archive and install while preserving user and network settings. This will only take about 45mins since it will not delete your home folder but will only replace the system files
2. you can also try doing an AHT apple hardware test so you can isolate it to either software or hardware
