Worms FAQ
How do I set Worms as my screensaver on a Mac?
Install SCRNSVRS free from the Mac App Store, select Worms 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 Worms as a live wallpaper?
Yes. Click Set as Wallpaper in SCRNSVRS and Worms plays on your desktop behind your windows and icons. You can use it as screensaver and wallpaper at the same time.
Is Worms free?
Yes. Worms is Free Forever in SCRNSVRS – no account, no ads, no subscription.
Is Worms a video loop?
No. Worms 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 Worms 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 Worms costs next to nothing in everyday use.
Which Macs does Worms run on?
Worms needs macOS Tahoe 26 or later.
