If you manage to get Docker Compose installed on that Mac (I don’t know Dockers limitations with Macs) but 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'

Then run;

sudo docker compose up -d

In a shell while in the folder with the docker-compose.yaml file you just created.
