Q: Security Update 2016-001 10.11.6 - Black Screen with Cursor

Hi,

 

After having installed the security update 2016-001 10.11.6 and the reboot as part of the installation process I get a white apple logo, the full white line blinks a couple of times and then I get a black screen with white cursor. Cursor moves with mouse but nothing else happens anymore and I don't get the login screen. This happened on my iMac (Retina 5K, late 2014) and on my MacBook Pro (2015).

 

Any help is greatly appreciated.

 

Best regards,

Tom

    Same problem with iMac 5K, no problems with MacBook 2016 though. Very glitchy update indeed.

    Have exactly same issue with my Macbook Pro (2011). I have to reinstall OS from cmd+r. Then I made the security update again and get the same issue : black screen, or white screen at startup. Now, i'm doing a TM restauration of 31 august restaure point.

     

    Can apple fix really quickly this "security" update ?

    Same issue here. Installed the update twice and got black screen each time. Only recovery mode possible. - iMac 5k late 2015. Very disappointing, Apple.

    After getting your computer working per some of the above suggestions, try downloading the update from the link below. This worked for me after the App Store download failed.

    I had this same problem.

     

    It seems that for some reason, the update reset my preferences to require me to sign in with a password when I logged in, and then instead of switching from the Apple startup screen to the login screen, it went black (but apparently, still wanted me to sign in.)

     

    I was able to start up in safe boot (hold the shift key after the startup chime), and then go into the System Preferences>Security & Privacy>General and unclick Require Password and Disable Automatic Login.

     

    Then I restarted as usual, and while the screen went black briefly, it continued with the startup as normal. I don't know what happens if you recheck those options to require the password at login, but since then mine has been starting up normally. So far.
