I am using QGIS 2.18.2 Las Palmas on a MacBook Pro running OSX 10.13.1 High Sierra. I followed Martin Isenburg's instructions how to install LAStools toolbox in QGIS and the LAStools menu is available under the "Processing > Toolbox" menu as it should be.
However, the number of tools (algorithms?) available to me in the menu is, I think, smaller than it should be. My LAStools installed menu shows 13 tools or menu items; the example in Mr. Isneburg's instruction shows at least 32 items.

Should I go unzipping these files in order to have a proper installation of LAStools?
