Fix 4. Run FSCK Command in Single User Mode

To run the FSCK command, you need to quit the operating system and enter Single User Mode. This allows you to run the command without any interference from the operating system. You can do this by rebooting your system and selecting the option to enter Single User Mode. Once in Single User Mode, you can run the FSCK command to check and repair any file system errors.

Step 4. To run a file system check on a Mac, type the command `/sbin/fsck_hfs -fy/dev/disk3s2` (replace "hfs" with the actual file system type, such as "hfs" for HFS, "hfsplus" for HFS+, or "apfs" for APFS, and replace "disk3s2" with the actual device name of the drive you want to check).

Step 5. Wait till the process completes, and run the reboot command.

If you're experiencing issues with the First Aid process failing, it's likely due to a corrupted or incomplete iOS update. To resolve this issue, try restarting your iPhone in recovery mode by connecting it to a computer and opening iTunes.
