Restart the computer while holding the Command and R keys to boot to Recovery HD partition, when it boots select the Disk Utility and Continue. Then select Macintosh HD on the left and first Verify Disk on the right and if that is OK Repair Permissions. If Verify Disk is not OK try to Repair Disk.

( it should be 31908 instead of 31909 )


 


but it's been repaired sucessfuly

got the apple in the middle of the screen, and the little whell at the bottom spinning... the spinning wheel dissapear and boom white screen again white the little wheel that appear and dissapear... bummer.Frown

Expert:  Mike replied 10 months ago.
Ok in that case I suggest you reinstall the system:

Do the same thing again but this time instead of Disk Utility click on Reinstall Mac OS X.
Customer: replied 10 months ago.

but i don't want to lose all my data ?

Expert:  Mike replied 10 months ago.
Do you have a Time Machine backup?
Customer: replied 10 months ago.

very old back up... 6 months ago maybe....

Expert:  Mike replied 10 months ago.
OK at least you have that but you should have Time Machine on all the time. Reinstalling the system will not normally cause you to lose anything. It just installs a clean system on top of the old one.
Customer: replied 10 months ago.

mike, it tell me :


 


COULD NOT FIND INSTALLATION INFORMATION FOR THIS MACHINE

Expert:  Mike replied 10 months ago.
OK try this:

Resetting the SMC & PRAM for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Wait fifteen seconds.
4. Attach the computer's power cord.
5. Wait five seconds, then press the power button to turn on the computer.
6. Press and hold the Command-Option-P-R keys before the gray screen appears.
7. Hold the keys down until the computer restarts.
8. Release the keys and hold Command - R try reinstalling again

Customer: replied 10 months ago.

Thanks Mike. it's too late, i was able to start the installation... it tell me 8 hours 10 minutes remaining at this time...


 


But what you told me about the reset for the pram i did already earlier i found this on youtube and it didn't work either....


 


 

Expert:  Mike replied 10 months ago.
OK it should not take that long but let me know after. GOOD LUCK.
Customer: replied 10 months ago.
