After updating my Late 2013 iMac 21.5 to High Sierra it hangs on boot up process. After booting into single user verbose mode I discovered it is hanging up on opendirectoryd. Does anyone know how to fix that error?
iMac
Apple updates in general have become subpar with regards to quality control as of late. I attempted to update my iMac from 10.13.1 to 10.13.2, only to discover that I could no longer login to any account, which includes local users. Reset the PRAM with no affect towards the issue. Tried to safe boot, but again, same results.
At present I have erased my disk and have a 10+ hour restore in progress.
The included picture is the verbose boot output of an attempt to login, prior to beginning the restore.
Try booting into safe mode instead Use safe mode to isolate issues with your Mac - Apple Support
If your iMac boots into safe mode try restarting it normally.
My IMAC won't boot into Safe mode. I tried logging in using a guest account and still nothing. The status bar stays at 100% and just hangs. I left it like that for over 6 hours and its still in same point. Its only in single user verbose mode that I can see that its hanging up on opendirectoryd.
It will boot into recovery and I have reinstalled high sierra. It still hangs. The end of the message when it hangs is this
Process[185] crashed: opendirectoryd. Too many corpses being created.
Process[186] crashed: opendirectoryd. Too many corpses being created.
Process[187] ..... and it keeps going indefinitely
You didn't say if you had everything backed up. Booted into recovery run Disk Utility to repair the hard drive, if it says it repaired anything run it again until it reports that it didn't repair anything.
If that doesn't work I'd suggest erasing the boot volume reinstall Mac OS then restoring your data and apps from your known good working backup. If you still have problems I'd suggest booting into Internet Recovery completely erasing the entire hard drive and then doing the install/restore.
No I don't have this computer backed up. I booted into recovery and ran the disk utility and it doesn't find anything wrong with the drive. I have run it several times and its says that everything appears to be fine. I figured someone at apple would know how to fix this. How can I contact someone at apple?
Well I am not completely out of luck. This was a new migration from my MacBook air to the iMac. I could do a clean install of the os and do the migration again. I have several backups of the mac air. I will contact apple. Thanks for replying
I actually spoke with an Apple representative and then they transferred me to a senior specialist and no-one could help me. They actually told me to do a clean install. I did and now the problem is gone. I feel that someone should have a fix for it but at this point for me I just couldn't wait. Good luck
Hi. Unfortunately no. I sent it in for repair and they couldnt fix it either. The HD had to be wiped and a clean install performed, so I lost my data. The iMac performes ok afterwards. I hope your problem can be solved. If you have a back-up try putting it back, that seems to help as well. Good luck and merry x-mas.
Unfortunately I had to wipe my machine clean and do a clean install. I talked to some engineers at Apple and was escalated to a Senior engineer and they didn't know how to fix it either. Sad really. You would think that someone would figure out a fix since it happens so often. Merry Christmas and Happy New Years!
Safe mode does not work, neither does online restore....the install goes well, but the boot process has been corrupted somehow.
Please don't say, "take to Apple Store," either.
Honestly, their solution to every problem seems to be wipe and start fresh.
That is just not good enough.
This is not 2002, when the only solution was always reformatting and reinstalling.
I paid good money for a computer that does not have these problems, so wipe and restore is not bloody good enough.
I know how to dig into the OS and underlying stuff, and I am a developer, as well.
SOMEONE knows where to start to figure this out.
I would like to hear a worthy response from THAT person.
I know where to start. Disk Utility, erase the hard drive and restore from your backup. If you want to "dig" into the OS by all means have at it, you'll end up in the same place and will have wasted more time than necessary.
And I have the same. Gutted as I've resisted clicking on the upgrade button For some time. I'm not technical, just a user, so off to the repair shop and more expense. As an aside, my iPhone Bluetooth connection in my car stopped working straight after IOS 11 and has kept dropping out ever since. Seems like the wheels are coming off......

Hate to say it but I believe you’re about to learn a hard lesson about backups. Good luck.
Will it boot into recovery? Do you have a working current backup?
IMAC 21.5 High Sierra won't boot up
