Magnets, in the context of macOS development, are not directly applicable as they are physical objects used in various fields such as electronics and mechanics. However, macOS does have a concept called "Magnet Links" which are used in peer-to-peer file sharing networks, such as BitTorrent. These links are essential for downloading files without needing a central server. This article will explore how to use Magnet Links in macOS, including how to open them and manage downloads via the Terminal.

Examples:

1. Opening Magnet Links in macOS:

   To open a Magnet Link, you can use a BitTorrent client like Transmission, which is a popular choice for macOS users.

   • Step 1: Download and install Transmission from Transmission's official website.
   • Step 2: Once installed, open Transmission.
   • Step 3: Copy your Magnet Link.
   • Step 4: In Transmission, go to File -> Open URL... and paste your Magnet Link.

   Alternatively, you can use the Terminal to open Magnet Links directly:

   open "magnet:?xt=urn:btih:YOUR_MAGNET_LINK"

2. Managing Downloads via Terminal:

   You can manage your downloads via the Terminal using Transmission's command-line interface, transmission-cli.

   • Step 1: Install transmission-cli using Homebrew:

   brew install transmission-cli

   • Step 2: Start a download using a Magnet Link:

   transmission-cli "magnet:?xt=urn:btih:YOUR_MAGNET_LINK"

   • Step 3: Monitor the download progress:

   transmission-remote -l

   • Step 4: Pause or resume downloads:

   transmission-remote -t [torrent-id] -S  # Pause
   transmission-remote -t [torrent-id] -s  # Resume
