For everyone who experienced this problem here is the answer.



A few days ago a took a plane and I took my MacBook Pro with me. In the plane I opened the MacBook and I got the question mark folder appearing. I thought it was because we were flying. On the ground I started it up again and the same thing happened. I had read al the forums about this problem but nothing worked for me. Luckily my little brother has the same MacBook Pro as I do so I could perform some hardware tests. First I mounted my HDD inside of my brothers MacBook and it worked! So then I thought the cable was broken. And I made a backup asap. Then I mounted my brothers disk in my MacBook and it worked to. So then I was really confused. Everything worked except my own HDD in my own MacBook. So then I thought I could swap my disk for his disk and swap data on the disks. The only down side was that my MacBook with his HDD was REALLY slow. I did some research about this problem and everyone says it is because the RAM, HDD to SSD etc. After al these problems I decided to buy a new HDD cable. I replaced it my own because it's cheap and so easy! And that was it! The MacBook worked perfect and fast again. I think this problem can't be fixed by software repairs. If the Mac will work again with a software fix your Mac will be really slow. It took the Mac 5 minutes to start up finder. I hope I could help some people with my story.

I just encountered this problem. I don't think it will work for everyone, but for for some reason when I plug in an external hard drive it will boot up correctly. I have a solid state, macbook pro (late 2013). After two days of my computer not working and every time it would give me that question mark folder I went to the mac store, they had no idea what was happening, they just thought it was corrupted; I plugged in my external hard drive and for some crazy reason it booted back up. Its done that to me a second time and sure enough, when I plugged the external in, it started up correctly. Hopefully that saves someone from thinking they've lost everything...
