Sad Mac
He is Happy Mac's evil brother. He only comes when something is very, very, very wrong with your older Macintosh. He is often accompanied by his minion the Chimes of Death. He can kill any computer he looks at. He is the Blue screen of Death's friend as well as Kernel Panic's, Sad iPod's and Red Ring of Death's.
Dude: I'm gonna turn on my Performa.

Performa: Beep.......(Chimes of Death followed by Sad Mac).

Dude: My Performa is dead!!! Why?! WHY?!
