Unable to turn on Norton extensions for Safari
After setting up Norton Safe Web or Norton Safe Web Plus, users are unable to check or turn on Norton extensions in Safari Preferences. Nothing happens or there is no-response, when they attempt to do so.
To fix this problem, boot your computer into Safe Mode, enable the Norton extensions and then restart your Mac in normal mode.
Update your Mac
-
In the Apple menu bar, click the Apple icon and select Software Update.
If your computer is not up-to-date, you need to install the software updates available for your computer that may appear in the list.
-
In the Software Update window, check the box next to Mac OS X Update, then click Install 1 Item.
When Software Updates displays "Your software is up-to-date", you can be sure that all available updates have been installed.
Start Safari and enable the Norton Extensions from Safari > Preferences. If the problem persists, go to Step 2.
Restart your Mac in safe mode

You might be asked to log in again.
Enable Norton extensions
