How to reset the macOS app?

[YamiYukiSenpai]

I turned on Jukebox mode and now the app won't launch

Jukebox mode is stored in macOS UserDefaults, so you can clear just that toggle without removing your saved server/profile settings.

Quit Musly, run this in Terminal, and open the app again:

defaults delete com.devid.musly flutter.jukebox_mode_enabled

The bundle identifier is com.devid.musly, and JukeboxService stores the toggle as jukebox_mode_enabled. The flutter. prefix comes from the legacy SharedPreferences API used by the app.

Flutter apps on macOS store their data in a few standard places, all named after the app's bundle identifier. First find the bundle ID:

osascript -e 'id of app "Musly"'

Quit the app, then remove its data (replace <bundle-id> with the output above):

# sandboxed apps keep everything here
rm -rf ~/Library/Containers/<bundle-id>

# non-sandboxed apps use these instead
rm -rf ~/Library/Application\ Support/<bundle-id>
rm -rf ~/Library/Caches/<bundle-id>
defaults delete <bundle-id>   # shared_preferences / NSUserDefaults

Only the locations that exist will matter. After that the app starts as on a fresh install.
