The day–night line creeps across a cratered plain under a low sun, long shadows stretching from the rims while the peaks catch the light first.

In the app you can adjust the colours, sweep speed, crater density and sun angle. It runs natively on your Mac, drawn live in real time – no video, never quite the same twice.

Terminator FAQ
How do I set Terminator as my screensaver on a Mac?
Install SCRNSVRS free from the Mac App Store, select Terminator in the library and click Set as Screensaver. macOS starts it whenever your Mac is idle, exactly like a built-in screensaver.
Can I use Terminator as a live wallpaper?
Yes. Click Set as Wallpaper in SCRNSVRS and Terminator plays on your desktop behind your windows and icons. You can use it as screensaver and wallpaper at the same time.
Is Terminator free?
Terminator is included in SCRNSVRS Unlimited. It's free for your first 7 days; after that Unlimited is $1.99/month or $9.99/year (€1.99/month or €9.99/year) for every screensaver, including new ones. It can also come up in Free this month, when 25 premium screensavers are free for everyone.
Is Terminator a video loop?
No. Terminator is rendered live on your Mac with Metal, so it never repeats and stays sharp on any display size. The clip on this page is a screen recording of the real thing.
Will Terminator slow down my Mac or drain the battery?
No. SCRNSVRS drops to 30 fps on battery and stops rendering when the wallpaper is covered by a full-screen app, so Terminator costs next to nothing in everyday use.
Which Macs does Terminator run on?
Terminator needs macOS Tahoe 26 or later.
