Owners of older MacBooks can repurpose the machines as home network attached storage servers, according to a guide published by Engadget. The approach ranges from simply enabling the sharing tools already built into macOS to replacing the operating system entirely with Linux. Most home NAS setups serve one of three purposes: hosting a media library, enabling collaboration and file sharing, or providing storage and backup.
Because older Macs carry a risk of disk failure and limited internal storage, the guide recommends relying on external drives for any NAS build. Before starting, users should erase the Mac, reset it to factory settings and update it to the most stable version of macOS the hardware supports. The setup also calls for a network connection and an Ethernet cable to link the machine to a router for speed and stability.
Two additions address common obstacles with aging hardware. Intel Macs with an HDMI output can use a headless HDMI plug, which makes the system believe a display is attached and activates the GPU for better video performance. The free Amphetamine app is suggested to stop the Mac from going to sleep.
The simplest route uses Apple's built-in Sharing settings in macOS. Users enable File Sharing, choose which folders to share and assign access privileges to individual users. The same setup can make data available to Windows and Android devices and can share content from an external drive. Shared files are reached through the Finder using an IP address the Mac provides.
For media playback, older Macs can run applications including Plex, Kodi and Infuse. Plex, the most widely used of the three, offers a user-friendly interface and remote streaming for a fee, while streaming inside the home is free. Installing it requires an account and the Plex Media Server, followed by a setup wizard in which users point the software to their media. The guide notes that Macs with low RAM may stutter when transcoding 4K footage, and suggests setting Plex to stream in Original quality.
More advanced users can convert a Mac into a full NAS system running Linux and open-source software, gaining web-based dashboards and other tools. The guide describes Debian as a relatively user-friendly option for both Intel and Apple Silicon Macs, paired with CasaOS or Umbrel, both of which provide documentation for the process. M-series Macs can also run Debian as a virtual machine, and users comfortable with the command line can run Docker directly on Debian.
Adopting Linux means the Mac no longer runs macOS and instead operates as a headless NAS managed remotely through a browser. Additional tools can extend the setup, including Nextcloud, which turns the machine into online file storage, and Jellyfin, a free, open-source alternative to Plex. Low-memory Macs may struggle with the Linux approach.
