I got hurry, my wife needs the macbook tomorrow for school. Can someonen tell me what to do? Reinstalling mountain lion  doesnt help. Reseting the PRAM and smd doesnt work either. The colored pixels are in a horizental lined pattern. When starting up the macbook everything seems to be okay untill the homescreen disappears.


MacBook Pro, iOS 6.1.5

    iOS is for mobile devices.

     

    Disconnect all peripherals from your computer.

     

    Boot from your install disc & run Repair Disk from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.

    Select your language.

    Once on the desktop, select Utility in the menu bar.

    Select Disk Utility.

     

    Select the disk or volume in the list of disks and volumes, and then click First Aid.

    Click Repair Disk.

    Restart your computer when done.

     

    Repair permissions after you reach the desktop-http://support.apple.com/kb/HT2963 and restart your computer.

    Uninstall the iOS app & repair permissions again.

    Thanks for your fast respond. I made a mistake. Im not running mountain lion but snow leopard. I think thats why i cant find a list with disks and volumes. Excuse me for my mistake.

    It doesnt work. Now the screen turned blue with a nearley transparent mouse cursor. Is there anything else i can do? Im pretty desperate.

    Run Apple's hardware test - Intel-based Macs: Using Apple Hardware Test

     

    Your other alternative is to call Apple tech support if you have Apple Care and request a replacement while your computer is being repaired or take the computer to an Apple store or an AASP.  Whichever is more convenient for you.
