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