USB

See it work

A real Galaxy phone over USB: open it from the menu bar, browse it in Finder, and drag files both ways. The phone's own screen is on the right.

It shows up in the sidebar

Your phone mounts under Locations, next to your drives. Open it in a Finder window and work with your files the way you already do.

Straight over USB

Plug in the cable, tap File transfer when Android asks, and you're connected. Nothing to pair, nothing to configure.

adb and MTP, sorted

Both protocols are handled for you — from the app, or directly in Finder. Every part of it is free.
