Session restore & file access
Quit whenever you like — the player comes back exactly as you left it.
What comes back on relaunch
- The playlist, the current track and position in it, and whether it was playing.
- Volume and speed.
- Shuffle and repeat modes.
- The full equalizer curve and preamp.
- Your skin and visualizer effect.
State is saved on quit and continuously in the background, so even a power cut loses at most a few seconds of state.
Which files MACSONG can see
Like every app from the Mac App Store, MACSONG runs inside a macOS privacy protection called the App Sandbox. In plain terms: the app can only read music you've handed it yourself — anything you open with ⌘O, drag in, or launch from Finder. macOS remembers what you've shared across relaunches, which is how session restore replays your queue without asking again.
One consequence: a playlist file (.m3u) can list tracks you
haven't handed to the app yet. The list will load, but those tracks won't play
until you've opened them — or their folder — yourself once:
- Press ⌘O (or drag the files/folder in),
- select the music the playlist refers to,
- done — MACSONG remembers, and the playlist plays normally from then on.
