Mac book pro not able to detect Internal hard drive
I am using mid 2016 15 inch macbook pro. last week I had an issue with mac not turning on and flashes a Folder with question mark symbol on it. After running some diagnosis, mac is not able to detect internal Hard drive. when checked with apple support in store, gentlemen who assisted me was not able to figure out what caused this issue and quoted me a price of $795 to replace MLB and SSD, as i do not have apple care. Another downside to this is I would lose all my data. I am really looking forward to a solution to this with out me replacing SSD and MLB. Was any one able to resolve it?
