Why NotchStar is not showing the song that is playing
If NotchStar shows nothing under Now Playing, start playback in an app that reports to the macOS Now Playing service, such as Music or Spotify. Then open the Home tab again. Players that do not report there will not appear.
Checks
- Press play in Music or Spotify and see if the Control Center media tile shows it. If macOS does not show it either, NotchStar cannot.
- Open the Home tab. The Now Playing card only runs while it is on screen, so nothing is read in the background.
- If you use Spotify or Music and the controls do nothing, check Automation. See Automation permission.
- Quit and reopen NotchStar. Since version 1.0.5 the helper that reads what is playing stops when the app quits.
Why it can be silent
Since macOS 15.4, third party apps cannot read the private media framework directly. NotchStar uses an open source adapter run through Apple’s /usr/bin/perl. If the stream is silent or exits, it falls back to AppleScript for Music and Spotify. Other players only appear if they report to macOS.
Normal behaviour
- Some players give no progress bar. That is normal.
- A browser tab may report differently from a desktop app.
More on the cause is in music controls not working. The Now Playing feature lists the limits. Other blank screens are in a tool is blank.
