What is the "Setup User" password which is asked for after updating?

Normally that works to switch between the "List of users" and "Name and password" login screens, but not always in this case. I support several dozen Macs, and one in particular always shows this when the OS is upgrade. I have tried switching to the Name and password login screen, but it didn't work.

Also, here's a thread where several posters experienced the same problem, tried the same fix (Control-Option-⌘-Delete), and it didn't work for them, either: http://forums.macrumors.com/threads/setup-user-login-prompt-after-update.1899186 /

The only fix I know is to do a forced shutdown. This can be accomplished by holding the power button for five seconds. In the case of desktop Macs, pulling the power cable also works.

IMPORTANT UPDATE: On another page, someone suggested using Option-Return. That didn't work either, but it did put the insertion point in the password box. Then I tried Control-Option-⌘-Delete, and it worked!

So the trick is to click in the password field first, then type Control-Option-⌘-Delete. When I did this, I was able to log on using my regular credentials.

I had the same question. I was in the middle of migrating my data from a Time Machine Backup and at one point, the "Setup User" came up.

When attempting the control-option-Command+delete+return combo, I did indeed get a username/password prompt, but any attempt at typing anything in was unsuccessful (kept deleting my keystrokes).

I simply left the computer as is and eventually, my regular login window came up and was able to log in successfully and all my data had been transferred.

So, I can only assume that the reason for the "Setup User" is an Apple created account used for the Migration process.

I had to hit the following keys to be able to login as myself, Control-Option-⌘-Delete-Return. After pressing all the keys I listed together, I was able to freely login to any account.

Just use Control-Option-⌘-Delete-Return. This will take you to the username and password prompt. enter your credentials and log in

so frustrated right now.

i'm doing a migration for a user in my company and i'm hitting this now. how infuriating to use these different key combos get to a screen you think you can login with and then every character you type in gets erased? what the heck?

i expect much more from apple.

the progress bar on the other mac seems stuck but it's too early to tell if it will continue that way or complete and work

this needs to be fixed, or they need to take out the migration feature....if this fails, i'm moving to carbon copy cloner and will see how the new mac handles that...

what garbage

Hi there,

I have exactly the same problem, I had to push cmd+return to geht the user and pw prompt but then can't type in anything. it gets erased and nothing works. I have an important migration running and I don't want to restart all over again... this ***** big time!

I also have this problem consistently. This occurs in 10.12.2 and 10.12.3. I cannot log back in during the migration because I cannot type into the name + password fields.

Even if I restart the process I will get back to the same problem.

I had this the first time yesterday.

I could work around this problem by setting the screensaver and the sleep mode to never.

Unfortunately in my case I had to uninstall the whole endpoint manangement framework because usually you are not allowed to set these settings to never in my company.

this is a real problem tbh.

If it's possible to set the password on the hidden user _mbsetupuser you could fix this

I tried

dscl . -passwd /Users/_mbsetupuser foopass

In terminal, which only worked temporarily

As soon as migration assistant started, the password reverted

Same with pwpolicy

Anyone know how to make the new password stick permanently?

Would be same for all hidden system accounts (e.g.: _uucp)

I am seeing the same problem. First time i eventually got stuck into a boot look. Support wiped and reimaged the machine and I tried a less aggressive install. It failed in the same way - not accepting any typed input from the username prompt, although I could enter the (unknown) password from the Seup User account.

I think @MacCrApple has the answer. I couldn't get in either and started freaking out because the fan was going full blast and the laptop was hot. Just left it overnight to finish migration, and when I came in the next morning, I could log in with my own username and password.

They should fix this, though. It's extremely confusing.

Just press Control+Option+Command+Delete keys and it will switch to full username/password prompt.

This worked for me on 10.11, thanks!

None of the fixes worked for me, however CMD + Return did the trick. This was on 10.11.6.

The "Setup User" login window appears whenever I use Migration Assistant when waking the system up from sleep. Since I get no progress bar in that screen to let me know if the migration completed, force shutdown wouldn't work for my situation.
I hold down the Option key, then press Return + Shift simultaneously. This presents me with a fresh login window.
