Mac Folder With Question Mark What Does It Mean?
If your Mac starts up to a Mac folder with question mark, it could mean one of two things:
(1) your startup disk is no longer working because either you previously started your MacBook from a different disk or your hard drive has failed,
(2) there’s no working operating system installed.
Question Mark On A Solid Black Background
It’s a scary thing turning on your Laptop only to find a solitary folder with a, question mark on a solid black background. But, worry not. As long as it’s not a hard drive that’s stopped working completely, there might be a way to get your Mac back to the way it was.
Press and hold the power button for 10 seconds to turn your Mac off.
Turn on your Mac, and hold Command (⌘) + R. This takes you to macOS Recovery.
Select Disk Utility, press continue and find your startup disk in the sidebar.
Click “First Aid” and hit Run. This should prompt your Mac to find errors and repair them.
If Disk Utility did not find or could not repair all the errors, you might have to reformat the disk, reinstall the macOS or restore a backup using the Time Machine.
