+1Hi everyone,
I'm trying to use MacOS Sonoma through the public Beta but with Jamf Connect it blacks screen. As soon as my macbook air M1 2020 boots up normally i get the jamf connect page. Now with sonoma i get few seconds of mouse and after that it black screen nothing is happening. i tried reinstalling sonoma and jamf connect not working. i tried to reset the authchanger through the terminal in recovery mode but it doesn't work. Do you have any idea?
Thanks
+1/sbin/mount -uw /
macOS 10.15 or later. >>>. mount -uw /System/Volumes/Data
Execute the following commands:
cd /var/db/
rm ./auth.db
rm ./auth.db-shm
rm ./auth.db-wal
Restart the computer by executing the following command
shutdown -r now
Hi MrSuaz, since we cannot log into a user account, and safe mode does not work either (we tried logging in but we get the same black screen) you mean we should try to run this in a terminal while in recovery mode, right? (We did make sure the volume was mounted before attempting to find the files we were supposed to delete)
One thing i am not fully understanding is this:
/sbin/mount -uw /
macOS 10.15 or later. >>>. mount -uw /System/Volumes/Data
What does this refer to? can you elaborate a bit on this? Thanks!

Sorry I think I was rushing and copied and pasted incorrectly.
But the information above on the is correct.
/sbin/mount -uw /
cd /Volumes/Macintosh\\ HD/var/db
rm ./auth.db
rm ./auth.db-shm
rm ./auth.db-walJust do an "ls" command to see what's listed after you change directories.
The original fix does work, but the key is mounting the correct volume. Here are the steps for the helpdesk:
-Boot into Recovery Mode
-Choose Options>Continue
-Select User, click Next, and enter password
-Go to Disk Utility>Continue
-Expand Macintosh HD volumes
-Click on Macintosh HD - Data
-Click on Mount in top-right corner and enter password
Macintosh HD - Data should now have the Unmount button in the top-right corner, indicating it's been mounted
-From top-left corner, Quit Disk Utility
-Go to Utilities>Terminal
-Type "cd /Volumes/Macintosh\\ HD/var/db/"
-Type one by one and press Enter:
rm ./auth.db
rm ./auth.db-shm
rm ./auth.db-wal
There should be no errors if commands ran successfully.
-Type "shutdown -r now" to reboot.
-Log in normally at first Mac login screen - the second login screen should now be gone.
If you run "/usr/local/bin/authchanger -reset -jamfconnect", which you should be doing anyway as a daily policy so everyone is authenticating via Jamf Connect, it will undo the settings and break it again. The permanent fix is to update Jamf Connect to v2.28. Confirm this version is installed on the Mac and you should be able to log in normally via Jamf Connect after a reboot.
You are my hero!
