Ive done everything possible on my Mac computer, like safe mode. reinstalling. etc. But nothing seems to work it just stays on the grey screen with an apple logo and the loading circle. Please can any one help me with this problem?

iMac, Mac OS X (10.6.2)

    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 Combo Updater for the version you prefer from support.apple.com/downloads/.

    But what if i dont have the snow leopard disk? Like i only have the two disk that came along with my mac will this still work?

  • Kappy Level 10 (265,746 points)

    What OS X version is on those discs? If it is Snow Leopard then they will work. If it's Leopard or Tiger, then they will not work.


    Do you have a bootable backup?

    My disk says its the Mac OS X version 10.6.2

    Then you can use the Disc One DVD. To boot from the DVD:


    Booting From An OS X Installer Disc


    1. Insert OS X Installer Disc into the optical drive.

    2. Restart the computer.

    3. Immediately after the chime press and hold down the "C" key.

    4. Release the key when the spinning gear below the dark gray Apple logo appears.

    5. Wait for installer to finish loading.

    Okay and how long will it take for anything to appear? After i press down the "C" key? And once its done loading, then what?

  • Kappy Level 10 (265,746 points)

    Just follow the instructions. It is all pretty self-explanatory. Once it's done loading follow the previous instructions.

    okay i will try it. But if it doesnt work.... :/

  • Jess202 Level 1 (0 points)

    Ive tried it. At first i thought it would work but then the disk or whatever it was said "At least 433.27 GB free 499.25 GB Total"


    What does that mean? And what can i do about it?

  • Kappy Level 10 (265,746 points)

    I have no idea what that means unless you add some context to it.

  • Jess202 Level 1 (0 points)

    I fixed it. But i lost all of my memory. Thank you though for the help!

    Glad I could help.
