I have a Macbook Pro (Retina) and recently my camera stopped working.

I didn't drop it or anything, it's just not being detected as a hardware.

When I try to see why, System Report shows me: 

No video capture devices were found.

I don't have Apple support anymore and I can't find any comprehensive guide or tips for this kind of problem - I just found issues with the camera, but not itself not being detected.

I tried to reset NVRAM and other things such as Diagnose mode, which gave me this error code above:

4HDD/11/40000000:SATA(0,0)

But on subsequent runs of this diagnose mode gives me no error. I also think it's unlike SATA has to do with the camera, as it typically uses USB.

I'm kind of lost and I just want to take it to assistance only if there are no other options, since I need my computer to work.

  • Could the error with the SATA/HD be affecting the Camera, possible a corrupted hard drive?

  • It's actually a SSD, not HD. But I performed Disk Utility's First Aid and it didn't report anything wrong. If you have any tips on that sense, I would much appreciate @IronCraftMan .

  • ok. Have you tried reinstalling OS X?

  • No, I haven't, but do you really think that could fix this or are you just trying something different? Also, since I backup to TimeMachine, not sure that reinstaling / restoring time machine backup would change anything.

  • I'm not taking about restoring from time machine. Either re-download the OS X installer or use Recovery HD and just reinstall. My guess is that since you didn't have any physical damage, something may be wrong with the driver.

Reset to default

For anyone experiencing this problem, I would suggest going with System Diagnose + NVRAM reset + SMC reset + Disk repair.

And if none of those work, follow @IronCraftMan advice and proceed with reinstalling OS X - you won't lose any data.

These steps worked for me.
