I am trying to help a friend with their machine. They are using an iMac (3-4 years old) running 10.12.
At first, their issue was at login. They would get to the login screen, enter their password, see the loading wheel for 1-2 seconds, then the screen would black out. But the machine is still on. Happened for a few times.
Now, though. It just powers on, get to the first loading screen, and then freezes. Tried multiple times. Same thing.
I wasn't sure what to do, so I had them follow this guide, What to do when your Mac displays a blank screen and the cursor after a macOS update.
- I had them reset the PRAM three times.
- Then boot to Single User Mode, and enter the commands in the article.
- There seemed to be some errors in the drive, but I am not qualified to interpret them.
- Here are screenshots of all the entries and readouts in Single User Mode.
What seems to be the issue, and what should I have them do next?
