Mac won't start, screen stuck on Apple logo and bar.

Hello,

My mid-2010 MacBook Pro running High Sierra turns on but won't boot: it gets stuck on the screen with the Apple logo and the progress bar, which completes but remains stuck. I installed the latest version of Flash Player the night before, and there may have been an incompatibility. In any case, since this High Sierra update, my Mac was already having increasing difficulty starting up.

- I booted my computer with Command V and the phrase "crash open directoryd too many corpses being created" repeats endlessly

- I cannot boot my computer in safe mode with the Option key

- I also tried Command R and the Disk Utility did not detect any issues

- I reinstalled High Sierra, which took over half a day, and there is no change...

I'm out of ideas... I can see the machine is intact since I can access Disk Utility etc., but there seems to be a problem with High Sierra...

    Hello,

    This issue of "crash open directoryd too many corpses being created" seems to have affected a lot of people because if you search for that phrase, you'll find plenty of discussions, including this one (4 pages in English where various solutions are proposed):
    https://discussions.apple.com/thread/7100079

    I went through this page and it appears that restoring from a Time Machine backup can help, and if that's not possible, you can use an external disk to do so:

    Step 1: Install the system on the external disk
    - connect the external disk to the Mac
    - boot into the recovery partition (hold Cmd and R during startup)
    - select the "Reinstall macOS" menu
    - specify the external disk as the installation destination

    Step 2: Back up your data to the external disk
    - boot the Mac from the external disk (hold Alt during startup and select the external disk as the startup source)
    - retrieve all data (videos, photos, documents, applications, ...) from all user accounts. This step is crucial because in the next step, you'll completely reformat the internal disk, thus erasing all data. So make sure to transfer everything!
    Note: If your external disk is large enough, you could partition it:
    - one partition for the Mac OS system (step 1)
    - one partition to receive the clone of the internal disk via SuperDuper!

    Step 3: Reformat the internal disk
    - ensure your backup is secure
    - boot the Mac into the recovery partition (hold Cmd and R during startup)
    - select the "Disk Utility" menu and completely erase the internal disk (see HERE)

    Step 4: Install the system on the internal disk
    - after formatting the disk, return to "macOS Utilities"
    - select the "Reinstall macOS" menu
    - specify the internal disk as the installation destination

    Step 5: Restore your data
    - boot the Mac normally. Note: this normal startup is already a victory
    - manually recover the saved items present on the external disk, even if you used SuperDuper!, as doing it manually helps avoid retrieving any potentially corrupted files. So reinstall your applications as you did on day one, transfer the folders (videos, photos, documents, ...) from each user account, ...

    Sure, it's very time-consuming, but well, you have to take it out on Apple for this big blunder they introduced in High Sierra. Apparently, version 13 is not bringing good fortune to this system. Can't wait for version 14!

      Hello Ritchi, I'm looking for help with a 2009 iMac. I'm stuck with a white screen and the prohibited parking sign? No commands work, even the command-V turns white after a little while? Any ideas, thanks.
