If you are the having the “too many corpses” error when trying to boot, the following fixed it for me 100% and it may work for you. Or it may blow up your machine…who knows…no warranty.
For me, this happened on 10.13.2 High Sierra
- Using the recovery partition, I installed osx on a usb drive. I didn’t go through set up or anything, because I just cared about the new recovery partition on the usb drive.
- I booted the ass computer in target disk mode.
- I connected my laptop to ass by firewire.
- I made all files visible on ass computer using these instructions
- I opened “Macintosh HD” on ass, and renamed all files including “hidden” files EXCEPT “Users” and “Applications” to “garbage[whateverthenamewas]” so I now have garbage.var, garbageSystem, garbageLibrary, etc.
- I then rebooted ass while holding down “option”.
- I selected the recovery partition on my usb drive as the startup volume.
- I selected “Reinstall OS X” from the prompt
- The following is the most important part:
During setup, I named the user the EXACT SAME NAME as my old user name.
tada! my computer started up looking like it never left me…same wallpaper…all my programs that were opened, reopened.
the last thing I did, so I wouldn’t have to redo my adobe settings was transfer the folder “Adobe” from “garbageLibrary/Application Support/” to “Library/Application Support/” and all files that started with “com.abobe” from “garbageLibrary/Preferences/” to “Library/Preferences/”
I hope someone finds this helpful 🙂
The cleanest solution if you are comfortable in terminal credit to rew10000 at https://discussions.apple.com/message/33021304#message33021304 for simplifying the solution I used in the trenches.
1. Hold down power button to shut down
2. Boot in verbose mode (hold down ⌘V, press power)
3. Confirmed that boot gets stuck with repeated “too many corpses being created” messages
4. Hold down power button to shut down
5. Boot in recovery mode (About macOS Recovery – Apple Support)
6. [Optional] From Recovery mode, Saved a backup image of Macintosh HD to an external drive using Disk Utility
7. From Recovery mode, using terminal, renamed all folders at the root level of Macintosh HD, except those with data I wanted to preserve, i.e. “Applications” and “Users”
cd /Volumes/Macintosh\ HD
ls -al (to see what’s there)
mv System _System
mv Library _Library
I didn’t bother renaming the files at the root level.
8. From Recovery mode, selected Reinstall macOS and installed on “Macintosh HD”
9. When asked to create a user, ensured that the short name (account name) matched my existing account name so that this user “inherits” the existing files in “Users”.
10. Back in business! (I guess I’ll go in and delete the old OS folders using terminal).
