My macbook 2011 17.5" won't start.

I tried all options listed here https://support.apple.com/en-us/HT201255 on how to boot with different keycodes. Only single user mode seems to work everything else ends in white screen a few seconds after the apple logo. I can choose the startup disk and tried booting from a backup but that also resulted in whitescreen.

Is there anything else I can try? Maybe reset the system completely somehow?

  • really? All options. I was just about to ask u to boot into verbose mode – Michael Ilie Mar 29 '18 at 19:10
  • Is anything plugged into the MacBook other than the power adapter? – Melvin Jefferson Mar 29 '18 at 19:12
  • No I unplugged everything. – Nightmare Mar 29 '18 at 19:24
  • I tried verbose mode. It didn't seem to make a difference. – Nightmare Mar 29 '18 at 19:25

    Have you tried AHT - Apple Hardware Test. Hold D while booting from a powered off state with the AC adapter attached. – Allan Mar 29 '18 at 20:49

If your Mac shows a white screen in recovery mode or internet recovery then there is a hardware issue on your mac.

My recommendation is to either contact Apple Support for an appointment or set up an appointment yourself via https://getsupport.apple.com/.

This could be a hard drive or display issue. If not then you are looking at a logic board replacement.

If you have a time machine backup or a separate backup of your things elsewhere then you should be fine, if not then you'll want to get the hard drive (if that is the issue) taken out and then purchase a new one, so you can take your current hard drive to the nearest data recovery center nearby you.
