Music Player Plugin for MioIsland

v2.0.0 — full rewrite. Real Now Playing info from Spotify, Apple Music, Google Chrome (YouTube / SoundCloud / 网页版音乐), with playback controls, draggable seek bar, album art color tint, and a pseudo-spectrum in the header icon. Replaces the v1.0.0 shell that only wired up MediaRemote.

Features

• Multi-source playback tracking with sticky source priority:
  • MediaRemote (private framework, any app that registers with MPNowPlayingInfoCenter)
  • Spotify desktop (AppleScript)
  • Apple Music desktop (AppleScript)
  • Google Chrome tabs (JavaScript injection into <video> / <audio> elements)
• Full playback controls — previous, play/pause, next, draggable seek bar
• Album art color tint — extracts dominant color from artwork, uses it as a soft gradient background in the expanded view
• Pseudo-spectrum in the Notch — three animated vertical bars in the header icon that pulse while music is playing
• Bi-lingual — follows MioIsland's appLanguage preference (zh / en)
• Graceful degradation:
  • Host too old (< v2.1.7) → shows upgrade banner instead of silently failing
  • Chinese music app running (QQ 音乐 / 网易云 / 酷狗) → shows "desktop not supported, try the web version" hint

Supported music apps

App	Supported?	How
Spotify desktop	✅ Full	AppleScript + MediaRemote
Apple Music desktop	✅ Full	AppleScript + MediaRemote
YouTube / YouTube Music in Chrome	✅ Full	JS injection
SoundCloud in Chrome	✅ Full	JS injection
Spotify Web Player in Chrome	✅ Full	JS injection
网易云音乐 / QQ 音乐 / 酷狗 (网页版) in Chrome	✅ Full	JS injection
网易云音乐 / QQ 音乐 新版桌面 app	🟡 Partial	MediaRemote if the app registers (macOS < 15.4 ok; 15.4+ may silently drop)
酷狗桌面 app / 酷我 / 咪咕 / 其他国产	❌ Not supported	No MediaRemote, no AppleScript API
Any app using MPNowPlayingInfoCenter	✅	MediaRemote

macOS 15.4+ note: Apple restricted MRMediaRemoteGetNowPlayingInfo to apps with special entitlements. The plugin auto-falls back to AppleScript for Spotify / Apple Music, and to JS injection for Chrome-based sources.

Installation

Prerequisite: MioIsland host v2.1.7 or newer

This plugin uses AppleScript to talk to Spotify / Apple Music / Chrome. macOS requires the host app's Info.plist to declare NSAppleEventsUsageDescription for that. MioIsland added this key in v2.1.7 — older hosts will show an upgrade banner inside the plugin and skip AppleScript sources.

Upgrade the host:

brew upgrade codeisland

Or via MioIsland's in-app update (Sparkle will prompt automatically).

From MioIsland Plugin Store (recommended)

1. Open MioIsland Settings → Plugins
2. Click 打开插件市场 (Open Plugin Store) — opens https://miomio.chat
3. Find Music Player v2.0.0 and click Install
4. Copy the generated https://api.miomio.chat/api/i/... URL
5. Paste into the Install from URL field and click Install
6. Restart MioIsland (menu bar → quit → relaunch)

Manual installation

# Download the latest release from GitHub
curl -LO https://github.com/MioMioOS/mio-plugin-music/releases/latest/download/music-player.zip
unzip music-player.zip
mkdir -p ~/.config/codeisland/plugins/
cp -R music-player.bundle ~/.config/codeisland/plugins/
# Restart MioIsland

First-run permissions

When the plugin fetches track info for the first time, macOS will prompt:

"Mio Island" would like to control "Spotify".app.

Click OK. Do the same for Music.app and Google Chrome when they come up. These permissions are granted to the host app once and remembered forever — subsequent launches don't re-prompt.

If you accidentally clicked Don't Allow, fix it in: System Settings → Privacy & Security → Automation → toggle Mio Island on for each target app.

Chrome-specific setup

To get Chrome playback (YouTube, SoundCloud, etc.) working:

1. Open Chrome
2. Menu bar: View → Developer → Allow JavaScript from Apple Events
3. Check the option (click if unchecked)

This is a one-time setting that lives in Chrome's preferences. Without it, AppleScript JS injection will silently return nothing for Chrome tabs.

Building from source

Requirements:

• macOS 15.0+
• Xcode 16+ Command Line Tools
• Swift 5.10+

git clone https://github.com/MioMioOS/mio-plugin-music.git
cd mio-plugin-music
./build.sh              # → build/music-player.bundle + build/music-player.zip
./build.sh install      # (not implemented — copy manually)

Install the build output:

cp -R build/music-player.bundle ~/.config/codeisland/plugins/

Restart MioIsland.

Source priority routing: sticky (last successful) → MediaRemote → Spotify → Apple Music → Chrome. First source that returns non-empty playback state wins. 3-second poll timer drives periodic refresh; Spotify and Music distributed notifications trigger immediate refresh for instant reaction.

Privacy

The plugin reads only:

• System-level Now Playing metadata (MediaRemote)
• Current track info from Spotify / Music / Chrome via AppleScript
• Bundle IDs of running apps to detect which source is active

It does not read:

• Your listening history
• Anything outside the "currently playing" state
• Anything from apps that are not music-related

Nothing is sent to any server. All processing happens locally.
