BOMB

1. Apple Macintosh users may encounter bomb errors when operating the computer. These error codes can be found on our Mac OS page. The below image is an example of a bomb.
2. PC users may use BOMB as slang for when the computer freezes, not allowing the user to input or get input out, usually fixed by hitting CTRL + ALT + DEL. Unlike the Apple Macintosh, when an IBM computer crashes you will not see the bomb.
