My macbook pro 2017 has an onboarded hard-disk and it is not visible when i try to upgrade OS. It shows me a flashing folder with a question mark it it. Can it be repaired or should i fix the hard-disk?
Thank you Brother. That's issue I just had with a Customer Mac. But this Mac turned the fan on 1 sec pulse every second. And the problem was the R7052. I had another donor board and took it from it. Now Mac boots fine. Thank you so much. Blessings Brother!
