Error message:

Spotlight is using the SafariQuickLookPreview extension, which must be closed before the software can be installed.

I have already closed safari.

What do I need to do to update safari?


This seems to work for me.

Go to Activity and search for 'safari':

enter image description here

Pick the entry 'SafariQuickLookPreview (Spotlight)' entry and kill it.

Then use the 'Try Again' button in the 'Software Update' pane in System Preferences.

    There is no 'Kill' command on Activity Monitor 10.14 (GB English). 'Quit' didn't work. 'Force Quit' did. So this works for me 😀👍

From a Terminal window you can also just kill the SafariQuickLookPreview process as follows:

pkill -9 SafariQuickLookPreview
