What if Disk Utility stopped repairing Macintosh HD? As is well known, Macintosh HD can be viewed on the Mac desktop and it is similar to the 'My Computer' icon in Windows.

If everything is fine, the message 'The volume Macintosh HD appears to be OK' will appear.
If some problems are found, you will see 'File system was modified'. Just run the fsck -fy command again until you see a “The volume Macintosh HD appears to be OK” message.

Step 4: Type reboot to exit Single User Mode.

Tip: Sometimes FSCK tool may fail to repair the target disk with 'The volume Macintosh HD could not be verified completely' error. Just click the forum from Apple to learn more information.
