If you manage to get Docker Compose installed on that Mac (I don’t know Dockers limitations with Macs) create a docker-compose.yaml file with the contents of;

services:

  jellyfin:

    image: jellyfin/jellyfin

    container_name: jellyfin

    # Optional - specify the uid and gid you would like Jellyfin to use instead of root

    user: uid:gid

    ports:

      - 8096:8096/tcp

      - 7359:7359/udp

    volumes:

      - /path/to/config:/config

      - /path/to/cache:/cache

      - type: bind

        source: /path/to/media

        target: /media

      - type: bind

        source: /path/to/media2

        target: /media2

        read_only: true

      # Optional - extra fonts to be used during transcoding with subtitle burn-in

      - type: bind

        source: /path/to/fonts

        target: /usr/local/share/fonts/custom

        read_only: true

    restart: 'unless-stopped'

    # Optional - alternative address used for autodiscovery

    environment:

      - JELLYFIN_PublishedServerUrl=http://example.com/

    # Optional - may be necessary for docker healthcheck to pass if running in host network mode

    extra_hosts:

      - 'host.docker.internal:host-gateway'

Edit the volumes so that the drive you want to use is exposed to the container and then run;

sudo docker compose up -d

In a shell while in the folder with the docker-compose.yaml file you just created. If everything works then the server should be running on port :8086 open your browser and make an http:// request to the ip of the server followed by the port.

Example; http://127.0.0.1:8096/
