24-Cell Slices FAQ
How do I set 24-Cell Slices as my screensaver on a Mac?
Install SCRNSVRS free from the Mac App Store, select 24-Cell Slices 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 24-Cell Slices as a live wallpaper?
Yes. Click Set as Wallpaper in SCRNSVRS and 24-Cell Slices plays on your desktop behind your windows and icons. You can use it as screensaver and wallpaper at the same time.
Is 24-Cell Slices free?
24-Cell Slices 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 24-Cell Slices a video loop?
No. 24-Cell Slices 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 24-Cell Slices 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 24-Cell Slices costs next to nothing in everyday use.
