Safari 12 won't update
Attempting to install Safari 12; pop up message:
“Safari” cannot be updated because its extensions are in use by “Spotlight”. Click OK and quit the application."
I quit Safari; i had only Dashlane extension installed; deleted that extension, but still receive pop up message.
Do not know how to quit Spotlight.
