About Kaset
YouTube Music in a browser tab is fine until it gets buried under forty others. Kaset gives it its own window. It's built with Swift and SwiftUI, the layout looks a lot like Apple Music, and regular YouTube works in there too.
It's free and open source under the MIT license, and the latest build ships as a plain .dmg. One catch: the app isn't signed with an Apple Developer ID yet, so a manual install means clearing the quarantine flag first. Prefer to skip that? Homebrew is an option.
