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