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