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