My icon of LibreOffice disappeared in my Mac dock and can't find it

I cannot find my installed LibreOffice application on my Mac computer in the dock where it had been.

You may not have successfully/permanently copied the icon to the dock.
There are a couple of places to look for the icon:

  1. Check your desktop to see if it appears there. If it does, just drag and drop it to the dock.
  2. Check your Applications folder. If LibreOffice is there, you can either right-click on it or drag and drop it to the dock.

Once it’s in the dock, right click on the icon and select “Options”, then “Keep in dock”.
Hope this helps resolve your issue.
