APFS Warning When Using First-Aid

Hello, support. Whenever I perform a first aid on my disk, I always get this warning in the log:

"warning: apfs_num_other_fsobjects (870) is not valid (872)".

I am on the latest version of macOS Mojave and, additionally, I'm also having problems booting up. An additional note: whenever I do perform first-aid in recovery mode, it either removes the disk from the list or shows a success message with nothing problematic in the log.

I wonder if there is something I could do to fix this?


Thanks,

Thearavid.

MacBook Pro 15", macOS 10.14

If the error occurs when Disk Utility is checking snapshots, then ignore it. Otherwise, backup and reinstall macOS.


Install El Capitan or Later from Scratch


If possible, back up your files.


  1. Restart the computer. Immediately, at or before the chime, hold down the Command and R keys until the Apple logo and progress bar appear. Wait until the Utility Menu appears.
  2. Select Disk Utility from the Utility Menu and click on the Continue button.
  3. When Disk Utility loads select the target drive (out-dented entry w/type and size info) from the Device list.
  4. Click on the Erase button in Disk Utility's toolbar. A panel will drop down.
  5. Set the partition scheme to GUID.
  6. Set the Format type to APFS (SSDs only) or Mac OS Extended (Journaled.)
  7. Click on the Apply button, then wait for the Done button to activate and click on it.
  8. Quit Disk Utility and return to the Utility Menu.
  9. Select Install OS X and click on the Continue button.
