Why does Apple now call an "upgrade" an "update" (on SysPref > Software Updates)?
Am I misunderstanding here?
System Preferences > Software Updates
"Advanced" options include to have Apple "install mac OS updates"
Is not an 'update' on the OS (operating system) actually an upgrade?
-- and a substantial decision to make?
I don't think that this upgrading to a new and different OS can happen
automatically, but only that one is automatically notified that a
difference OS is available for the user's participation in installing;
correct?
