A very convincing crash screen. Perfect for your lunch break.
A crash screen that looks just real enough to make colleagues hesitate. The modern style shows a big sad face and a percentage that slowly climbs to 100 before “restarting”; the classic style is a 90s text-mode error with a blinking cursor.
Write your own stop code and pick blue, green or black. An original parody – no real error, no harm done.

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