blue outline
I have seen some posts about people seeing a blue outline on their macs. I had recently turned on a setting in chrome not safari of highlighting selected text when it is clicked. I had been looking online and in System Preferences to see if I can turn that feature off but I realize that it was only within the chrome window. So if you want to take it off you go to the settings within chrome go to accessibility and you turn off the highlighted feature. You're very welcome.
