Turning an Old MacBook into a NAS: macOS Sharing, Media Servers, and Linux Options

The content outlines ways to reuse an old MacBook as a network-attached storage device instead of leaving it unused. It compares a simple macOS-based setup with more advanced Linux-based configurations and explains the main trade-offs in effort and capability.

■ Basic macOS NAS setup
- Factory reset and wired Ethernet connection
- Folder sharing, user permissions, Windows/Android access, and external drives

■ Media server options
- Plex for home streaming and media library management
- Infuse as an alternative without Plex
- Low-RAM Macs may stutter with 4K transcoding; original-quality streaming can reduce this

■ Advanced Linux-based NAS
- Replacing macOS with Debian and adding CasaOS or Umbrel
- Running Docker for app installation and management
- Nextcloud for online file storage and Jellyfin as an open-source Plex alternative
- Debian can also run as a VM on M-series Macs

It is suited to viewers with an unused MacBook who want a low-cost home storage or media server project and are deciding between built-in macOS tools and a Linux-based approach. Viewers can use it to understand the main setup paths, the software involved, and practical limitations before choosing a configuration.
