Too many corpses being created!

Your Mac running macOS High Sierra 10.13 stopped at the startup screen that shows the Apple logo with a progress bar. You entered verbose mode with cmd-V and it shows a repeating message of "Too many corpses being created."

No, your Mac wasn't infested with zombies. There's no need to smash it with an axe and throw it in fire. This is what you could do:

  1. boot and hold cmd-R to start up from macOS Recovery
  2. if Filevault is on, mount the disk with Disk Utility and password
  3. run these two in Terminal
  • cd /Volumes/Macintosh\ HD/var/db/caches/opendirectory
    (this should be one line and also use an escape character \ before each white space in the disk name, such as My\ Fancy\ Disk\ Name - if you actually just type /Volumes/, then a few letters and press TAB, it should fill the rest)
  • mv ./mbr_cache ./mbr_cache-old
  • restart

The first startup after running these commands takes a bit longer than usual as the cache is recreated, but subsequent startups will take the normal amount of time.

    I am really new at this and am confused, I get the first comand done and fine, but the last command says it does not exist – mv ./mbr_cache ./mbr_cache-old
