Q: An error occurred preparing installation. Please run this application again.
I downloaded the installer for El Capitan and run it. It prepares the update, I chose the installation drive, it takes my password, and then it tells me the computer will restart and starts its 30 second countdown. Then I get "An error occurred preparing installation. Please run this application again". Over and over and over again.
Any ideas? I'm a little afraid of Apple updates these days as is. 2009 MacPro Desktop.
Mac Pro, OS X Yosemite (10.10.5)
