Serial number removed during the installation of El Capitan

It's more about post a solution rather than a question.

On my a MBPro 2010 I have that I gave to my mother that I upgraded from Yosemite to El Capitan.  After the installation, a dialog box kept popping up asking for a password to iCloud.  Entering it, she would get the fan of spinning of death and he locked the computer... also I was unable to download the updates.

After a quick search on the internet I found an article to check if the serial number has been removed... and after I checked, he said order number; Not available.

The same internet article provided a method for reinstalling the serial number, but they wanted me to install a third-party program to do... I was not comfortable doing that.

I went to the local Apple dealer/repair and they sent me to call Apple.  I did and had to go to second level support and they asked mt to re - install El Capitan.  Done under Apple ID my mother and mine, the MBPro still shows under my name, and nothing has changed.

Is returned to the local Apple retailer and they ran diagnostics and find nothing, but when they had to enter the serial number to run the diagnostic program is re-entered the serial number and everything seems to be fine.  Lucky for me that this has been done before they charged me $120 bench tax.

I hope this helps someone out there in the Appleverse...

Looks like you almost fell victim to a certain type of adware. Installation, upgrade or reinstall that OS will not mess with serial number.
