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