In the app you can adjust the colours, fog, typing speed and character rows. It runs natively on your Mac, drawn live in real time – no video, never quite the same twice.

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