Macbook 2016 stuck in an update loop

Hello!

As the title says, I received my 2016 macbook pro 15' last week and everything was fine until today when my macbook shut down on its own and attempted to install an update. However, prior to completing the update, I get the following error message:

"A critical software update is required for your Mac, but an error was encountered when installing this update. Your Mac can't be used until this update is installed."

I am given the option to either try again or shut down which leads to the same situation and my laptop is now stuck in this loop. I was hoping someone would be able to assist me with this. Thanks!

MacBook Pro, iOS 10.1.1

In trying to set up and log into my new Macbook Pro 15" with TouchBar, I got only as far as entering my network information when I received the error message:


A critical software update is required for your Mac, but an error was encountered while installing this update. Your mac can't be used until this update is installed.


On the advice of others posting here, I did a re-install of the OS from Command-R. This did not help me. I tried several times.


Then (also from within Command-R) I erased and re-formatted the hard drive, re-installed the OS, and for the first time was able to get as far as inputting my time zone and setting up a user account.


The first thing I did once I finally gained access to my new computer was to visit the App Store and download updates. One of the App Store system updates needed a re-start.


When the computer re-started, it made it to the log-in screen. However, after I entered my password, the screen froze, with a spinning beach ball. I was not able to login again to the account.


I did a hard re-start. When the system started again, I was prompted for my WIFI network, and then received the same error message:

A critical software update is required for your Mac, but an error was encountered while installing this update. Your mac can't be used until this update is installed.


Help??!

I had the same problem . It was fixed by doing an internet system software installation. Immediately after pressing the start button press option command r together. This caused a completely new system to be installed and it fixed the problem. It also did not delete the user info already transferred and it was nice that that step did not have to be repeated. I called Apple tech support and they set me on this path.

Same thing happened to me. Had to reboot with Command-R MacOS Recovery and re-installed the OS. I didn't have to do internet recovery, good thing because I did not have Wi-Fi at the time. One problem I did experience - when it came back up I had a very difficult time reconnecting to my Wi-Fi and I had to go through diagnostics to get it to connect. Could this be the underlying problem with the update, it's not able to connect to Wi-Fi in the process?
