Also the look-and-feel of Executor (when not within an application) is different from a real Mac, i.e. The somewhat technical term is that they are 'clean', meaning that Apple would have no legal case against them. Ardi never used any code from Apple and has never disassembled or even looked at Apple's code. Development started on a PDP-11 (!) and the first beta ran on a SUN-3.įrom that on the environment was developed into Executor. To have a demo of what the libraries could do, Ardi developed an environment for the libraries so that they could show Word running on a UNIX box. The goal was to develop a set of libraries for UNIX to ease porting of applications originally developed for the Macintosh. The developers literally started with nothing except lots of public information about the Macintosh (like the Inside Macintosh series of technical manuals). To compare these two is comparing apples and oranges (pun intended), however a number of people have raised questions that the following might answer.Įxecutor was developed from ground zero.

Both emulate a Macintosh and both are developed with the DJGPP GNU C compiler. These two emulators have little in common. Executor versus vMac Executor versus vMac
