I just wanted to post this if anybody else has the same problem. After updating to 10.10.2 the jellyfin service would exit after a short time after trying “Applying migration '“RemoveDuplicatePlaylistChildren””. My jellyfin user didn’t have write privileges for some of my library directory’s I added some time ago. To fix just make sure the user running jellyfin has write access to all your media directory’s So maybe this will help somebody else who is googling for this.

This was the status of the systemd service:

systemctl status jellyfin.service
