Description: MacsBug is an assembly-language-level debugging tool for the
Macintosh and Power Macintosh computers. You can use it to display
and set memory and processor registers, disassemble memory, and set
execution breakpoints. You can step and trace through RAM and ROM,
and display many Macintosh data structures. The command set is
extensible through user-written drop-in commands called "dcmds"
(Debugger Commands).
To install, place MacsBug at the main level of your System folder, and restart your computer. MacsBug will automatically be loaded by the Macintosh operating system at system startup. It will be invoked whenever an application program causes a fatal system error. More information on how to use MacsBug can be found in the companion publication: "MacsBug Reference and Debugging Guide" by Apple Computer, Addison-Wesley Publishing, ISBN 0-201-56767-9
