2020 Mac Pro black screen w green lines
macOS high Sierra - went to turn it on and had black screen w green lines. 5 months old, never dropped. What can I do? 2 hours from Apple store won’t turn on now at all
MacBook Pro 13″, macOS 10.13
Definitely have Apple look at it, but try this...
1.. Shut the machine down.
2.. UNPLUG the power lead to the computer and any peripheral devices.
3.. leave it for 10 minutes.
4.. Hold power Button in for 10 seconds
5.. Connect everything back up and restart.
