Question: OS 10.13.? Mac won't boot. Verbose mode last line "too many dead corpses"
I have a fix that works. You need to boot from an external drive as current system is not bootable. I am a GUI person so not able to give terminal commands in Single User Mode but sure someone else can. Create an external bootable system preferably 10.13.3 and boot. Enable Root user. Run terminal command show invisibles "defaults write com.apple.finder AppleShowAllFiles YES". Relaunch Finder. Navigate to internal drive, usually Macintosh HD and go to /var/db/caches/opendirectory and delete the file MBR..... Shutdown and startup in Safe Boot, left shift key held down on reboot. Login in and restart. Should all be good. Run usual updates, Onyx, check Anti Virus Software etc. Enjoy!
