macOS Mojave keeps going back to login screen after 30 seconds

I updated a mid-2012 13" MacBook Pro to Mojave yesterday. After the installation process, when I click on a user and log in, within 30 seconds the screen flickers and I'm back at the login screen. This happens for all accounts. I have tried repairing the disk, doing an Internet recovery install (in case a file was corrupted), basically exhausting all of the repair processes. I cannot do anything in terminal or settings because it just pops me out to the login screen within 30 seconds. Ultimately I did a Time Machine restore and it is back to pre-Mojave state.

Has anyone run into this? Granted this is an old machine but it works just fine. I am holding off upgrading my new laptops until I can be certain this was either a fluke, machine-dependent issue, or that Apple has a fix. My laptops are my work, can't afford to not have them operating and don't want to waste 10 hours on a failed install and then do a restore.

MacBook Pro (13-inch, Mid 2012)

2.5 GHz Intel Core i5

10 GB 1600 MHz DDR3

Intel HD Graphics 4000 1536 MB

Thanks,

So after 4 separate upgrades to Mojave and the restores to High Sierra, I had a phone call from Apple with some guidance from their engineers. The very nice and patient Kelli walked me through the following. Pleaser try this at your own risk:

Boot into Recovery (Hold Command and R down and turn on the computer)

Open Disk Utility, then:

Select the startup volume.

Make note of the name of the volume (usually "Macintosh HD"). If the name of the volume is dimmed, click the Mount button and enter the password of a user who can unlock the disk.

Make note of the number shown next to "Available:".

Quit Disk Utility.

Select Utilities menu > Terminal, Replace the bolded hard drive name with whatever your drive is called, and enter these two commands:

cd "/Volumes/Macintosh HD/Library/Audio/Plug-Ins/HAL"

assuming it takes this command, follow on the next line with the following:

mv *.plugin ..

If it takes this command, quit terminal and then restart the computer in normal mode and login

When I did this, all worked fine afterwards.

Best of Luck with it!
