Remove recent documents history? I recently got a MacBook Air and am getting used to the macOS interface... Liking it so far but still relearning how to do some basic stuff.

For example, right clicking on VLC, and all the porn I've been watching comes up! Don't want to risk that popping up if someone else is using my computer for a few moments.

I've tried setting the Number of recent items under system preferences to none, but vlc still remembers all my filthy video titles! What gives?

In windows I could clear my recent documents easily enough, or use a tool like ccleaner to clear system cache, browser histories, recent documents etc with one click.

Can you recommend something similar for Mac? 

(I know the best solution for this is separate user accounts - but would like to be confident that I could pass my laptop quickly to someone at a moments notice without all my recent activity being two clicks away! 

Thanks for any help.
It is generated by Spotlight

You can make it so that nothing shows up (aka deactivating it) by doing the following.


System Preferences > Spotlight > Privacy > +
then select your Macintosh HD (or whatever your HD is called)
then click choose.


Now that should do it.
