A few things
worth knowing.
What do I get?
Everything: all six effects, the five painted wallpapers, the glass wallpaper maker and every update after. You pay once, there's no subscription.
How do I unlock the app?
After you pay, we email you a license key. Open the app, paste the key, done.
Can I use it on more than one Mac?
A $7 key works on 1 Mac, a $15 key on up to 10. Got a new Mac? Remove the key from the old one in the app and paste it on the new one.
I lost my key.
Search your inbox for "KoiArt license key". Can't find it? Write to support@spacerrs.com from the email you paid with.
Will it slow my Mac down?
No. It draws on the graphics chip, halves the effect on battery and in Low Power Mode, and stops while a full-screen app covers the screen or the screen sleeps.
Do clicks go through the snow?
Always. The effect sits over your screen but every click goes straight to what's under it.
Which Macs does it run on?
macOS 14 Sonoma or later, on Apple silicon and Intel.
How do I change the wallpaper?
Open KoiArt, go to Wallpapers and click one. It's set on every screen. Want your own? Glass turns any photo into a wallpaper.
Can I get a refund?
Only if KoiArt doesn't work on your Mac and you tell us within 3 days of buying. Write to support@spacerrs.com. Full details on the refund policy page.
