I downloaded 10.11 from the App Store and proceeded to install it on my MacBook Pro 2013 15" system. The upgrade seemed to be going fine but with about 7 minutes left the computer simply shut off. I restarted it and it sat there for a few moments then shut off again. I restarted it a few more times with the same result.
I had to restore from my backup to get the system back running.
I tried the same thing a second time after doing some system testing and clean up with the same result.
I contacted Apple Support and they did not have a solution other than wait a few days and try downloading it again and installing.
I have updated the O/S before and never had a problem.
Any ideas?
