The other day my MacBook Pro just spontaneously halted during regular usage.
The screen went black, aside from the mouse cursor appearing once every 10 seconds (exactly).

I don't seem to be able to move the cursor myself and upon trying to reboot the device (cold), I get the Apple Inc. logo / loading progress-bar combo, and then its straight back to being an unresponsive black screen with a cursor that flashes at ten second intervals.

Does anybody understand what's going on and/or how to fix the problem so that I can resume normal operation? Cheers.


Hardware:

  • MacBook Pro.
  • 15" Retina Display.
  • Early 2013.
  • i7 Processor.
  • OS X Yosemite.
  • 8GB RAM.
  • 500GB Solid-State Storage.

Update:

SMC reset worked, but no change. NVRAM reset worked, i think (had to type firmware password) but it brought me to the recovery tools. Cannot boot into Safe-Mode or Single-User-Mode. Apple Diagnostics / Apple Hardware Test fails to launch. Recovery-Mode start-up brings me to the same screen as the NVRAM reset. Verbose-Mode also fails.

  • Have you tried resetting the NVRAM, SMC? Can you boot into safe mode? – Allan Jun 29 '16 at 22:28
  • @Allan Nope. None of those help. SMC reset worked, but no change. NVRAM reset worked, i think (had to type firmware password) but it brought me to the recovery tools. Cannot boot into Safe-Mode or Single-User-Mode. Apple Diagnostics / Apple Hardware Test fails to launch. Recovery-Mode start-up brings me to the same screen as the NVRAM reset.

  • Interesting that the diagnostics fails to launch. Do you have any bootable media? Can you boot from a USB or DVD installer? – Allan Jun 30 '16 at 1:37
  • I would say so, I haven't tried. Is that relevant? I will check. I'll try and boot a live Debian distro off a thumb-drive. – tjt263 Jun 30 '16 at 5:32
  • It removes your internal SSD from the equation. If you can't boot off the USB or DVD, you have (most likely) logic board issues. – Allan Jun 30 '16 at 11:24
