    A friend of mine has a new MacBook Pro 2016 with touch bar, and setup by migrating his user account from his old MacBook Pro via migration assistant. He also has another account on the MacBook which he setup before doing the migration. Both user accounts were working fine until he installed the 10.12.1 update and now when he logs into the user account that was migrated he gets a black screen with the cursor. The other user account works fine.

    I'm trying to help him and have tried to power the machine off and fire back up (by using Touch ID button as power) and holding shift to boot into safe mode but safe mode doesn't happen, it just boots back to the login screen. Recovery mode also doesn't happen, just boot back to login screen.

    Am I missing something here? Does the new MacBook Pro have a different method for booting into safe or recovery mode? Also is this the best approach to troubleshooting the issue? Where to go after safe mode?

    Is it best to boot into recovery and then re-install the OS and will this keep the user accounts intact? Or does the SMC need resetting?

    I've read about graphics issues but how does this explain the other user account that logs I fine? Is it a corrupt account?

    Thanks!

    It's shift till you see the login screen mate.

    Recovery is command + r
    If that don't work then...
    Option + command + r for internet recovery

    Ah in that case safe mode didn't work. Recovery isn't booting to recovery screen. Maybe I'll try internet recovery.

    Anyone have any idea what issue could be? Corrupt user account? Will a reinstall of the OS still keep user accounts intact?

    Hi! I just bought a new MacBook Pro YESTERDAY 12/27/16 and am having the same post migration black screen w: cursor problem post migration. Really crazy. Called Apple and they didn't have any ideas more than the standard ones that have been mentioned already on this thread. The Apple tech told me to just return it which sucks and is a huge pain in the ass since I've already spent time migrating the old one, etc.
    Did you ever find a fix for this? Thanks.

    Same issue here with my new macbook pro 13 ... when I came in this black screen w / cursor state I just type my password + return and it goes back to the desktop, all works fine. Not happens all the times, the screen goes to an strange condition when the TouchID won't recognize my finger. I'm sure this is just a bug... hope Apple solves this issue.

    Hi everyone,

    I used the following solution to successfully get my iMac working yesterday. Hope this helps you too :)

    What is important here, is that when you enter these commands hit return (enter) quickly after typing each command in - otherwise they tend to automatically start running, sometimes halfway through writing them, and the whole process doesn't work. Took me about three attempts to figure out that this was what I was doing wrong initially. So here's what you need to do:

    ----

    First, you need to shut down your Mac, if it's powered on. Pressing the power key for a couple of seconds will do the trick.

    Next, you have to boot your Mac in single-user mode. That's done by pressing the Command and S keys at the same time, right after pressing the power key. If you did it right, you should see a whole bunch of lines on the screen in what is a Terminal-like interface.

    (I've seen someone recommend that you reset the PRAM three times before booting in the single-user mode. There is no harm in doing that. Hit the Command, Option, P and R keys at the same time, right after you power it on, and wait until you hear the startup chime for the third time before letting go. Then, quickly press the Command and S keys, to get you into the single-user mode.)

    You then need to type the following commands:

    1. /sbin/fsck -fy
    2. /sbin/mount -uw /
    3. rm -f /Library/Preferences/com.apple.loginwindow.plist
    4. rm -f /var/db/.AppleUpgrade
    5. reboot
