I turn on my Mac, hear the startup sound, the apple logo appears, and then the screen goes blue. Once it's blue, it dims, light up and a pinwheel pops up. Then the process repeats.

 

I tried a SMC reset and a PRAM reset. Neither worked.

 

I have a 24" iMac with i7 Intel processer, 2x4 GB RAM and 1TB of internal memory.

 

Please, please help me. I have a report due Friday and everything is saved on there.


iMac, Mac OS X (10.6.4)

    Reinstall OS X without erasing the drive

     

    Do the following:

     

    1. Repair the Hard Drive and Permissions

     

    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.

     

    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

     

    2. Reinstall Snow Leopard

     

    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

     

    Download and install the Mac OS X 10.6.8 Update Combo v1.1
