    I downloaded this installation this morning and my whole system went to trash! I was not able to open any of my applications.  I couldn't even open my settings to uninstall.  I had to do a SHIFT + Shutdown to get into an area where I could uninstall. Is this update mandatory? Has anyone else encountered this problem? If so, how did you get around it?
