Allow FullCovered to access music players

Fullcovered requires access to the music player to get information about the track from and control the music player. To allow this app to access the music player, you can click OK to the popup window when you launch this app for the first time. You can also set this in the system preferences (System Preferences / Security & Privacy / Privacy / Automation).



track information
  • Loved and rating: shows different items depending on the music player. Apple Music shows both loved and rating with read/write (Apple Music streaming service only supports loved feature). Spotify shows read-only rating(popularity) only. Hermes shows loved only, with read/write attributes.
  • Artwork position: the position of the artwork on screen. "L/R Toggle" means that the artwork position changes at every new track.
  • Get artwork from a third-party database if available: get artwork from a third-party DB when playing Apple Music streaming. This app tries to find the best match by using the track's name, artist or album name. The artwork may not be found or mismatch.
  • Toggle multiple artworks: In the local library of Apple Music or iTunes, a track can have more than one artwork. If this field is checked, FullCovered shows the artworks in turn at every time interval set by "Toggle interval (sec)".



video player
  • Back to the video list after playing video: If not checked, YouTube videos related to the video just played will be played continuously.
  • Autoplay video of your next track: The videos corresponding to your music list are played continuously. The video is the first video from YouTube search for your music.
  • Search YouTube by: This is a search parameter provided by YouTube.
  • Exclude restricted content: This is a search parameter provided by YouTube.
  • Sort by priority: Show your preferred video at the top by sorting the title of YouTube search results.
  • Exclude lyrics video: Try to exclude lyrics videos from YouTube search results.
  • Exclude cover video: Try to exclude cover videos from YouTube search results.
  • Alternative play: check this button to play videos in countries where YouTube Music doesn't support.
  • Max waiting time to video start: Increase this time if "Back to the video list after playing video" is checked and this app returns to your video list directly after playing an ad.

* FullCovered uses YouTube API services to search videos and to play the video.
"Back to the video list after playing video" and "Autoplay video of your next track" may occasionally not work correctly due to the ad. video. 
YouTube has a limit on the maximum quota of video searches per day. This limit refers to the total number of searches for this application, not the number of searches per user.
The search field on the youtube page doesn't work properly because it uses a key-mapping from the app hotkey to the YouTube hotkey.


system settings
  • Start a music player with FullCovered: FullCovered invokes the selected music player when launching. If the selected music player is "Auto selection", this app doesn't invoke any player.
  • Prevent display and computer sleeping while playing: If this setting is on, FullCovered prevents the system from sleeping while a track is playing. If this setting is off, or a player's state is paused, stopped or etc., it follows the system settings of macOS.



Known issues

  • In Apple Music streaming: When adding a track by "Play Next" or "Play Later", Apple Music or iTunes doesn't support information of the track.
  • In Apple Music streaming: Sometimes, it fails to get artwork from the third-party DB when opening this app. It could happen due to a slow network or slow response from the DB server.
  • In Apple Music Library (Catalina): It doesn't support displaying multiple artworks at this moment(Jan 2020) due to Apple API issues. This feature will be back after Apple API supports it.
  • Update from the old version: If the app crashes at launch, delete the following files and folder (, ~/Library/Preferences/com.smk.FullCovered.plist and ~/Library/Caches/com.smk.FullCovered) and reinstall the app.
