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:
- boot and hold cmd-R to start up from macOS Recovery
- if Filevault is on, mount the disk with Disk Utility and password
- 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 asMy\ 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.

For a newbee like me working with terminal in Apple is not a easy thing. When I run the first one using “/Volumes/…” and “TAB” and filling it out with the “…/opendirectory” command, the answer is “is a directory”. Ten I run the second line, but the answer is: “No such file or directory”. Can you help me out?

Thank you so much for posting this. After five stressful hours of my MacBook Pro not starting up I found your solution. You saved me a clean install.
