Kernel Panic Screensaver!

So awhile back I was thinking, “You know what would be funny? A screensaver that fakes a kernel panic!”

For those of you who might never have seen one, a kernel panic is basically the most shocking crash that you can get on a Mac. It’s Apple’s equivalent to the famed Blue Screen of Death.

What a great way to play a prank on someone, or frighten yourself.

So here is the end result, a harmless screensaver that faithfully emulates the horrifying experience of a kernel panic. It comes complete with a misleading Quartz Composer Preview so that the KP is all the more terrifying.

    Hi did you ever tryed with a dual screen mac? the main screen is copied to all other screens and the KP is shown on all screens. in real it is only shown on the first (or on laptops on the internal).
    anyway good work, but there is a little bit to improve :-)

    yeah, creative idea, especially in view of the fact that Mark Russinovich’s famous Windows BSOD screensaver has been around for, what, over a decade? But nevertheless, kudos for getting the job done.

  9. Brian Says:

    Awesome!!!! But on dual screens, it does show on both— when it shouldn’t.

    Other than that, this is brillaint :P

    Don’t panic! It’s just a screensaver

    In November, I wrote about a screensaver for Windows PCs that emulates a Blue Screen of Death. And in a wonderful twist, it’s offered up by none other than Microsoft. Of course, the Macintosh has an equivalent to the BSoD…

    Thats a great prank, the only question is how do I install it remotely using ssh and then make it the default screen saver and then set the time to have it start in 3 minutes?

    Awesome idea, wish the dual-screen thing worked properly. Also, I had a problem with the iTunes pausination. It didn’t pause, just lowered the volume to almost nothing, and when I awoke it it came back to normal for a second before dropping out again. I like the idea, but really wish it would actually pause the music before muting, and then restore the volume to the level it was before.

  30. violinist Says:

    Actually, if music is playing when u get a KP, u hear the music cut off, but repeat the last half-second constantly.

    For instance, if an audio file was playing while the machine KPs, you’d hear:

    “This is what happens when an audio file is playing during a kernel panic-ic-ic-ic-ic-ic-ic-ic-ic-ic-ic-ic…”

  31. Alex Celeste Says:

    The screensaver works on my MacBook (I downloaded it when I had an iBook G4), but instead of showing the kernel panic animation over the screen it turns the screen white then shows the animation.

    Just thought you’d like to know about that bug in your very neat screensaver.

    I downloaded this on both my machines, but then I noticed something. When my iMac actually does KP, the screen goes grayscale. With this screensaver, it just gets like a gray haze, but you can still see all the colors. Just thought I’d mention that. Also, maybe that’s the difference between a KP on OSX Tiger and OSX Leopard. I run both.

  51. otheroom Says:

    This reminds me of an application that was floating around in OS 9. When it was run you’d get the little restart dialog window with the bomb making you think your computer crashed. When you rolled the mouse over the dialog to click on the restart button the window would jump away form the mouse. Great fun to put in someone’s startup items ;)
