For whatever reason the ARM version of Transmission does not work well on my M2 laptop - it downloads quickly at first and then drops off to zero, and had some other bugs (the x86 version always worked flawlessly). I tried playing around with different settings, running their nightly builds, etc, and nothing fixed it for me. In the end I searched for other clients and found them all filled with ads and bloatware, and decided to use this excellent open source command line client instead:
It has a few frontends built on top of it (linked in the project readme), but I just run `torrent download <magnet link>` and it downloads at full speed / with no issues.
