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