    Since I installed Mac Sierra server three days ago, I've had to restore the entire machine from backup twice.

    What happens is I do something like try to start Safari, but it won't start from the dock. About that time, I get a pop-up that says that the MacOS needs to repair my Library so I can run applications.

    My login user ID is pre-loaded, but no matter what password I enter (like the one that goes with the login shown), this dialog won't accept it.

    Then, to make matters worse, if I reboot, I then get a two field login prompt and no matter what I type in the fields (valid user names) nothing is accepted.

    Then, I have to restore the entire machine from a backup if I want to get back in.

    Has anyone seen this issue?

    I've never seen this. Do you have a screenshot?

    No, but the next time it happens, I'll post a screenshot.

    Wherever my feet take me…
    I've seen this (or similar) issue before. I find that it needs an admin user's credentials. It usually comes back a few times. Pressing the Cancel button (or Command-Period) closes this window.

    The problem isn't that I can't close the window. And, it won't take the admin password (root) either. The real problem is once you reboot, no passwords work at all.

    I asked this question in the thread where you originally posted this: Are you trying to sign in to the server with an Open Directory or Active Directory account? If so, don't do that; make a local administrator account on the server and sign in with that.

    I tried to log in to the Mac with the user account and with the root password. Neither worked.

    One time there was a little red dot next to the mac login text field and when I hovered over it, it said that the network was unavailable or something like that.

    Make an account in the system preferences Users & Groups panel and use that to log in at the server. Do not use Open Directory users to log in on the desktop of the server. I can't find documentation about this right now but it's always been problematic and not recommended.

    I never used any Open Directory user ID to log into the machine, always a regular user. I created a root user using Apple's technique. But, when this issue happens, no login works.

    Where are the home folders located?
    Have you made a regular admin account, rather than root, and logged in as that? Running as root in a Mac server has led to strange behaviors at times for me, and there really is no need to do it.

    Its bound somewhere. Don't use a backup, restore the machine with the recovery disk or over the internet first.

    I have the same message popping up, after installing High Sierra on a mid13 iMac.

    It is not a network computer. We actually rarely use it and it has been slow as hell from the very beginning...

    Any way, has there been a solution to this messsge? Disk utility didn’t solve it...
