What is BBRT ? 

(MCE) Machine Check Exception is a type of computer hardware error that may occurs when a computer's (CPU) central processing unit detects any such  hardware problem.

If you didn't notice any crash, probably the error was successfully corrected. Still, you should install 'mcelog' to keep track of such events:

install using sudo yum install mcelog  -y if it's not already installed and then run mcelog to see the errors. By the looks of it, you have a hardware problem.

The events will be logged to /var/log/mcelog.

You can also run:

sudo mcelog --client

The second error is coming from the initial-setup-gui-0.3.9.36-1.el7.centos package.systemctl disable initial-setup-text.service
