Sunstream Screensaver

Windows 10 / 11

Download Sunstream.scr

Installation:

1. Right-click Sunstream.scr and choose Install.
2. Or: go to Settings > Personalization > Lock screen > Screen saver and choose Sunstream.
3. Press Preview to try it. Any key, click or mouse movement closes it.

Windows may say the publisher is unknown. Choose More info > Run anyway.

Does it not start by itself? Windows never starts a screen saver while a video, a video call or an app like Teams keeps the screen awake. Close it, or check with powercfg /requests.

macOS BETA

Download Sunstream-macOS.zip

Installation (macOS 11 Big Sur or newer, Intel and Apple Silicon):

1. Unzip the file and double-click Sunstream.saver.
2. If macOS refuses to open it: go to System Settings > Privacy & Security and click Open Anyway, then double-click again.
3. Choose Sunstream in System Settings > Screen Saver.

macOS warns because the screensaver is not notarised by Apple. Alternatively, in Terminal: xattr -dr com.apple.quarantine ~/Downloads/Sunstream.saver

Linux BETA

Download Sunstream-Linux.tar.gz

Installation:

1. Unpack it: tar -xzf Sunstream-Linux.tar.gz
2. Try it: ./sunstream-linux/Sunstream.AppImage --no-sandbox
3. Start it automatically when the computer is idle: ./sunstream-linux/sunstream-idle.sh 10 (minutes). To do this at every login, see the README inside.

Works with GNOME (also Wayland), KDE and other X11 desktops. Some systems need sudo apt install libfuse2.
