I would try to take a movie out that is already currently matched and showing up ok
Plex dance it and add it back to see if it shows up again
I tried Death Race the way you have it named and it does show up, just as the wrong movie
Death Race 2000 (1976)
I didn’t realize you added 60 movies that aren’t scanning into Plex at all so, I see what you’re saying
I don’t know anything about mac but is it possible somehow your drive permissions changed somehow?
