Sad Mac

A Sad Mac is a symbol used by older-generation Apple Macintosh computers (hardware using the Old World ROM), starting with the original 128K Macintosh, to indicate a severe hardware or software problem that prevented startup from occurring successfully. The Sad Mac icon was displayed, along with a set of hexadecimal codes that indicated the type of problem at startup. Different codes were for different errors. This was used in place of the normal Happy Mac icon, which indicated that the startup-time hardware tests were successful. In 68k models made after the Macintosh II, a tune (Chimes of Death) was played. Models prior the Macintosh II crashed silently and displayed the Sad Mac, without playing any topne. PowerPC Macs played a sound effect of a car crash, and computers equipped with the PowerPC upgrade card used the three note brass fanfare death chime(A, E-natural, and E-flat) same as the Macintosh Performa 6200 and Macintosh Performa 6300.

A Sad Mac may be deliberately generated at startup by pressing the programmer's key interrupt switch on [[Macintosh computers that had one installed, or by pressing Command and Power keys shortly after the startup chime. On some Macintoshes (e.g. PowerBook 540c) if the user presses the command and power keys before the screen comes up, it will play the chimes of death; the chimes are a fraction of normal speed and there is no Sad Mac displayed.

Sad iPod
On the iPod, if damage or an error occurs in the hardware or the firmware, for example, if its files are deleted, a Sad iPod appears. This is similar to the Sad Mac, but instead of a computer, there is an iPod with a sad face, and doesn't play a death chime. The icon also lacks a nose, and the trail off is on the other side.

Sad Tab of Death
On the Google Chrome Application, it is possible to "kill" a page, however there are several methods to do so. Upon doing so, it will cause a version of the Sad Mac to appear, with a caption clip that can say either "He's dead, Jim", "Aw, Snap!" etc. This will lead the user to refresh the page by force. Sad Tab of Death comes in the form of the first tab of a folder, with an "x~x" facial expression on it, and was created for comedic purposes.
