Final Cut Pro Plugins with MacOS Sierra

Hello,

I just bought my new Macbook Pro with the Sierra OS 10.12.4 in it.

Yesterday, I bought some plugins from PixelFilmStudio for FCPX but I can not find them in the software.

In fact, There's only like 2 plugins on 9 which were installed and one which was judged "too old" for the macbook.

The instruction says that if I have OS Sierra, I have to install it manually by going on "Motion Template" but in this finder, I can not find it... Not even the "Macintosh HD" in the finder, or "user" or "movie", nothing except my softwares and my documents.

Does anybody knows if it is possible to install these plugins and how ?

There is my plugin list that I have :
- Pixel Film Studios - FCPX Colorist 1.2S

- PFS - FCPX LUT Loader 1.4 (this is the too old)
- PFS - FCPX Overlay Aperture Light 5K 1.1

- PFS - FCPX3D Abstract 1.1 (this one is installed)

- PFS - Proana Volume 2

- PFS - Proglitch Volume 2
- PFS - Prolumetric 1.1 (this one is installed)

- PFS - Propixie 5K 1.1

- PFS - Prowarp

Thank you for your help,
