Transmission
Transmission is a BitTorrent client for macOS that helps you download, manage, and share torrent files and magnet links with a simple native interface.
What is Transmission?
Transmission is a native BitTorrent client for macOS that helps users download and share files over the BitTorrent protocol. It is designed for people who want a lightweight desktop app for handling torrent files and magnet links without a complicated interface. Common uses include downloading open-source software, Linux distributions, and other legally shared large files, then organizing transfers, bandwidth limits, and seeding behavior in one place. The app supports standard torrent workflows such as adding downloads, pausing and resuming transfers, setting speed limits, and using a web interface for remote control. Transmission is also available on other platforms, but the macOS edition is built to fit typical Mac desktop usage and system conventions. It is published as an open-source product and is widely used by people who want a focused, low-overhead torrent downloader.

Safety overview
Status: Use with caution
Transmission itself is a legitimate BitTorrent client, and network access is consistent with its purpose because it connects to peers and trackers to transfer files. The main risk comes from the content you download: torrents can contain unsafe, unwanted, or infringing material even when the app is genuine. Review torrent sources carefully, scan downloaded files before opening them, and confirm the app is signed and installed from the official Transmission website if you want to verify the copy on your Mac.
Recommendation: Keep Transmission if you actively use torrents or magnet links and want a lightweight Mac client for managing them. If you do not use BitTorrent, you can remove it without affecting normal macOS operation, though any active or queued transfers in the app will no longer be available there.
