In the app you can adjust the colours and speed. It runs natively on your Mac, drawn live in real time – no video, never quite the same twice.

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