- Your library on all your Macs: what you get from the store on one Mac is installed on the others too, and deleted everywhere when you delete it. Pictures, videos and mini programs from your other Macs wait in the library until you use them, unless Download All Content is on; a download shows its progress on its item. - Settings › Storage shows how much your library takes on this Mac, with Reset Data, Remove Download and Clear Cache. - Each display keeps its own scaling, speed and dynamic wallpaper options; the details change the displays picked in the preview. - Options, how pictures and videos are shown, permission answers, sound and the frame rate limit now stay on each Mac instead of syncing. - Deleting anything asks first, and says when it goes from all your Macs and can be restored on the web for 30 days. Uninstalling content also deletes what it saved to sync. Deleting built-in content works the same way: it goes to Recently Deleted on the web with what it saved, and restoring it there brings both back on all your Macs. - Widgets and companions are deleted, downloaded or have their download removed from their tile's menu, and keep their options and sound when taken off the desktop and added again. - A dynamic wallpaper shown on several displays is heard from one of them only. - Fixes and stability improvements.

• Run Each Content Separately (Settings › Advanced, off by default): each wallpaper, widget and companion package runs in a process of its own, so one that crashes or stops responding doesn't take the rest along. • Content wakes your Mac only at the frame rate it draws at, which saves energy. • Pixel Cat uses less power and System Receipt less memory. • The first click on a widget while another app is in front is no longer lost. • Other fixes and stability improvements.

Sound • Dynamic and video wallpapers, widgets and companions that play sound each have their own Mute switch and volume. So nothing plays unexpectedly, they start muted, including ones added before this update: turn off Mute in their Sound section to hear them. Picture and video wallpapers • Set each video wallpaper's playback speed, from 0.25× to 2×. • Restore a picture or video wallpaper's default display and speed in one click. • The details show a wallpaper's description. • Import wallpaper folders that come with a description file. Importing the same wallpaper again asks before replacing it, and keeps its categories, playlists and display settings. Content • Importing what looks like a newer version of content you have asks to update it. • Dynamic wallpapers and widgets can use their own fonts and draw videos. • Looping videos play on without a pause. • Other fixes and better stability.

Displays • What's on a display stays with it. When an external display is disconnected, its wallpaper, widgets and companions move to a similar display, and come back when it's plugged in again. • Each set of displays (for example the laptop alone, or with a monitor) remembers its own places for widgets and companions. • Opening or closing the lid no longer restarts what's on an external display. • The Displays page lists displays seen before, and you can forget the ones you no longer use. • A layout from another Mac puts each widget and companion on the matching display. Content • Drag a mini program (.zip or folder) onto the Wallpapers, Widgets or Companions page to add it. • Widgets stay on the desktop when you use Show Desktop or Mission Control. • Live previews keep running while a screenshot tool covers the screen. • Sharper previews in the inspector, and other fixes.
