Plex Veteran, but New Install on New Mac Won't Show Any Media Files



Hi! I have tried multiple video file types and in different folders with full permissions on my High Sierra OSX, but absolutely nothing is showing up in my Plex "Movies" or "TV Shows" sidebar. I have deleted and created new Plex sidebar folders and pointed them back at the different Mac folders, but absolutely nothing is working. My two other computers (windows 10 and Mac Sierra) have never had a problem with this before. I've also tried deleting all Plex install files and re-installing, but it still isn't showing any media files.

Thank you so much for any help or guidance!
