Hello Eileen, I expect a heap of criticism for what I’m about to say. I always recommend installing a new OS from a USB key and wiping the hard drive before doing the installation. You can then restore your data and settings from a Time Machine backup. I’m so tired of seeing unpredictable behaviour when people just do an upgrade on top of the existing OS. My husband is currently on a long phone call with a client who tried to install El Capitán on top of Yosemite, and her machine will no longer boot.
Once the machine is in a bad way, the best thing to do is a clean install from a USB key and not copy everything from Time Machine, but reconfigure the machine from scratch and only copy back your data from Time Machine.
