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