I wonder how much stuff its including there. I use the alpine package for transmission and its 1mb https://pkgs.alpinelinux.org/package/edge/community/x86/tran...

These 1mb are only for the daemon and not taking into account the dependencies. Although I’m pretty sure the linux version is more lightweight in general because the gtk dependency is very likely to already be installed.

Let me stay upright. 15M seems a lot. What's in there ? High-def country flags for Retina ?

edit: ok, size is ~4.5M on my Debian, of which transmission-gtk accounts for 3.6. Maybe graph libs are bigger on mac ?

3.8mB is an auto-update framework – https://sparkle-project.org

3.5mB is for a Quicklook plugin, so that Torrent files can be previewed in the Finder.

4.5mB is UI 'stuff'. The Cocoa 'nibs' that define the application UI tend to be bigger than comparable GTK XML files.

It's a multi-architecture package - ARM and Intel.
