Sequence Shuttle is Sequence's desktop app for macOS. It mounts your projects as a local drive in Finder and moves media in and out of Sequence faster and more reliably than the browser. You don't need it to edit — everything in Sequence works in the browser — but it's the quickest way to bring in a lot of footage and to work with a project's files straight from your Mac.
To install Shuttle, mount a project, and start transferring files, see the Shuttle section.
