How to add the FMSite.net Facepack to FM19
Download either the torrent + updates, or all 10+5 parts which are in .rar archive format and use a tool such as 7-zip for Windows or The Unarchiver for MacOSX to extract their contents.
First extract the base pack (or its parts 1-10), then move to the updates but do it in order (1-5). Every time you extract an update, overwrite the files and folders it asks you to.

Move the folder "Player" to:
\Documents\Sports Interactive\Football Manager 2019\graphics\
Create the folder "graphics" if it doesn't exist.

Open Football Manager 2019 and go to Preferences > Interface.
Click the "Clear Cache" button.
Enable "Reload skin when confirming changes in Preferences".
Click the "Reload Skin" button.
There should be a box that pops up saying 'loading image data for the new skin'. Once this is done your graphics should be working within the game.
