App store indicated macOS High Sierra installed but the current version running is OS X 10.9.5 how do i get High Sierra to load upon start up?
My iMac currently says I am running OS X version 10.9.5. I downloaded macOS High Sierra and the app store page indicates that High Sierra was installed. Upon start the mac is still loading OS X. How do I load High Sierra? In the past the OS updates have auto loaded.
iMac (21.5-inch Mid 2011), iOS 10, OS X 10.9.5
