We have a few iMacs running Sequoia 15.5 and Jamf Connect that are going to black screens after you log in. Both local user accounts and IdP accounts are affected, but I can see the user folder is being created when we log in against our IdP, I get the account creation message but it just hangs on the black screen. Local admin account is having the same problem. I’ve tried uninstalling, restarting, and reinstalling Jamf Connect, but the problem persists. Uninstalling and logging in as a local admin user causes a beach ball to spin, but it sits there and doesn’t not progress. I’ve checked the config profiles and license and they’re all valid, and this isn’t happening fleet wide, just randomly.

if I create a new user through Jamf, the user will create, but I can’t log into that account, it immediately dumps me back to the JC login window without any feedback. I can see the new user’s account by running dscl . -list /Users UniqueID but it still hangs. Resetting authchanger doesn’t help either.

I’ve seen a similar problem where it’ll hang on a black screen when a user has an account in the system, but their /Users/ folder is empty. This isn’t the case now, as the local admins have a populated folder, and the IdP users don’t have a folder at all when I attempt to log them in the first time.

Any ideas? I’m in the process of reprovisioning one of them as test to see if it’s a computer issue.
