Verify boot volume at startup
Verify the file system data structures of the boot volume. Any underlying Storage System (e.g. Core Storage, APFS) is verified before the target volume itself. In order to verify boot volume, it must be locked. This will result in apps not responding during the operation. This is completely normal and apps will begin responding when the operation has completed.
