Mac Book Pro 2012 not starting pink apple logo

Hi all,


I have a Mac Book Pro 2012 which suddenly was not able to start. During the start-up it does not get further the 1/2 of the start-up bar and the Apple logo displays pink as well as the background screen.


Tried several resets but without positive results.


Appreciate any suggestion/advice


Best regards, Rodrigo

Dear all,


Thanks to all your suggestions. I have followed all of them except approaching the Genius Desk.


Finally the I got it run with re-starting with pressing the "C" key. Which presented me the Mac OS X installation screen. From there I could see that the Hard Drive had an "Incompatible Format" state. User uploaded file

After erasing the HD I was able to re-install Mac OX X 10.6.7 from DVD


Weird is that during the Hardware test no euros were detected.....


Again, thanks to all and hope this help others with similar problems

Your Mac is at the stage of the boot up process where kernel extensions are being loaded. These are mainly device drivers, and are stored in: /System/Library/Extensions



Please try the following, in order. Stop at the step where the issue is resolved:

  1. Reset your Mac's SMC.

    Reset the System Management Controller (SMC) on your Mac- Apple Support

    Fans, keyboard backlight, status indicator, battery indicator, display backlight, power button, close/open the lid, sleep or shut down, battery doesn't charge, MagSafe indicator light incorrect status.

    Hold down the <shift><control><option> keys, and then, press the power button. Hold all of them for, at least, 10 seconds.

  2. Reset your Mac's NVRAM.
