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