Macintosh Toolbox


Macintosh Toolbox

Software routines, drivers and APIs that performed the graphical user interface functions on all Macintosh models up until the iMac. The original Toolbox was hardware, its functions stored on a ROM chip either soldered to the motherboard or in a socket. From the iMac forward, the Toolbox ROM is loaded from a file on the hard disk. Apple developers also included much of its functionality in the Carbon programming API.
