Fix invalid node structure
You can repair the invalid node structure on macOS error through the fsck command or reformatting.
Fix invalid node structure error through fsck command
After data recovery is done, please try macOS' built-in Disk Utility to fix the invalid node structure error:
- Launch "Terminal" from "Utilities."
- Input the "diskutil list" command and hit the "Enter" key on the keyboard to get the corrupted volume ID, such as disk0s2.
- Unmount the volume by using umount /dev/volume identifier. Note: You need to replace the volume identifier with an actual one. For example: umount /dev /disk0s2.
- Execute sudo fsck_hfs -fy /dev/disk0s2 to get the process started. If the file system is APFS, execute sudo fsck_apfs -fy /dev/disk0s2.
- Use the “First Aid” tool in “Disk Utility” to verify and fix the invalid node structure error and other issues.
If you receive the error: "Invalid node structure. The volume Machintosh HD could not be verified completely after running Disk Utility." It means Disk Utility fails to fix the invalid node structure error. You can try to format this corrupted Mac volume as long as you have recovered data from the corrupted Mac volume successfully.
Fix invalid node structure error through formatting
When the invalid node structure error appears, formatting can help you prepare the drive for use again.

- Open "Disk Utility."
- Choose the target drive from the left sidebar and click the "Erase" button on the toolbar.
- Set the name and file system.
- Tap on the "Erase" button to continue.
