Content here at renderosity does not come with an installer, so you must do it all yourself - as RHaseltine already mentioned.

What you must do: unzip the downloaded package(s), you will get a folder with more or less subfolders in it.

Just copy the content from the runtime-folder into the runtime folder where your DAZ-content is located (you specified it when installing daz).

For example: you look into the runtime dir and see "geometries", "libraries", "textures"... the files inside these directories must be copied to the fitting folder at your DAZ-Content-Dir (look there inside "runtime"-folder).

Be careful!!! If there is already existing a folder with the name of a folder which you want to copy OSX will overwrite the existing folder! If finder tells you that there's already a folder with that name, abort! And then look inside the folder of your unzipped-content, copy by hand the files from inside this folder into the correspending one at your daz-content...

If you are not sure where it is just look at the preferences -> Content Library -> click there at "Content Directory Manager" -> a new window will pop up, take a look at "current dictories", double click at "DAZ Studio Formats" and "Poser Formats" -> it'll show you where your DAZ-Content is located at your system.

Pfew, hope you understand my crappy english :P - english is not my first language...
