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