Moireloop for macOS
The wallpaper doesn't show
Make sure Moireloop is running (icon in the menu bar). Quitting the app removes the live wallpaper; closing the window doesn't.
The wallpaper pauses
That's on purpose: Moireloop pauses when the desktop is hidden, asleep or on low battery. Settings › Energy saving to change this.
Open Moireloop at login
Settings › General › “Open Moireloop at login”.
Multiple displays
Settings › General › “Same wallpaper on all displays”: turn it off to pick one per display.
My wallpaper doesn't follow my music
Check Settings › Music › “Wallpaper follows your music”. It works with the Spotify and Music (Apple Music) apps installed on your Mac, not with their web players. The wallpaper changes as soon as a song plays and comes back 20 s after it stops.
Restore purchases
On a new Mac, open Settings › Purchases › “Restore purchases” with the same Apple ID.
