There may be an issue with the fan.
MacBook Pro 15" Retina (Late 2013 Mid 2014)
Black screen but I can see my cursor.
After a few test, like reinstall Sierra OS, I run an Apple Diagnostics ("D" at boot up) with this result:
There may be an issue with the fan.
- Reference Code: PPF004
- Additional reference code: PPF003
Which fan matches with the code PPF004, right or left?
Or I need the both?
Thanks =)
Is this a good question?
