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