TV Sender for streaming / Syphon / what (where are the) directories

First - thank you Boinx for the Sender for Streaming.
Im n OSX 10.9 (Mav) , where do I find the “Compositions” & “QC Plug-Ins” folder(s) to copy the .qtz and syphon.plugin to referenced in the Help PDF ?
Thanks for the help.

In the Disk Image containing the Help file and the plugins, there are links to the target folders. Just drag the files there.

thank you Bastian…
