Something strange happened:

  1. I closed my macbook pro while using windows 10

  2. When I opened it again it didn't wake up for a while so I forced it to shut down by pressing the power button for 10 seconds

  3. When I restarted the computer, it could not find any OS and just displayed a flashing question mark. I tried starting the computer while pressing the usual special keys, but nothing worked.

  4. I gave up and went for 2 days of vacations, instead of being angry.

  5. I just came back from vacations (after two days) and everything works fine.

Update

Today nothing works, it is impossible to find the SSD, even when I try OS X Recovery over the Internet Disk Utility does not find the SSD (just a drive of about 1.28 Go where the OS X recovery is installed). I tried reseting the NVRAM and the SMC without any luck.

Is it necessarily a disk failure?

Update 2

It's not a disk failure since I installed my SSD into a friend's Macbook Pro (same model: retina 15" late 2013, 2.3Ghz) and it works properly. I also tried to insert his SSD into my Macbook Pro and it is not recognized.

I returned my computer to an Apple reseller...

  • Did you try to boot into Recovery or Single User mode? – nohillside Apr 25 '16 at 13:56
  • Yes it didn't help. I think my question is clear enough now. – arthur.sw Apr 25 '16 at 15:14
  • Diagnosing potential hardware issues is always difficult without physical access to the machine, so it helps to be very specific. In step 3, what actually was displayed, a flashing question mark as shown in the picture behind the link? Which "special keys" did you try? Also, what does "nothing works" mean now? Same problem as in step 3? – nohillside Apr 25 '16 at 15:21
  • The only way to find out whether this is a disk failure is to run the tests recommended in the answers to the question you've already linked to. – nohillside Apr 25 '16 at 15:22
  • Yes it is the question mark flashing, of course. I obviously tried all appropriate special keys. Now the disk is not recognized at all anymore so I can't run the tests. – arthur.sw Apr 26 '16 at 8:28

I don't know where it comes from though...
