I have a whole lot of floppies from that period with dev tools but I don't think I kept much MacApp stuff because it required Mac Programmers Workbench (MPW) to compile which was pretty cumbersome. I started using Consulair Mac C, then later LightSpeed Pascal and then LightSpeed C which were pretty awesome. Of course Metrowerk's CodeWarrior overtook these as the main alternative to MPW, including PowerPlant which was a sophisticated application framework. Using C for Mac development was a bit of a pain in the early days because of the stack calling differences between Pascal & C (before the declarations were built into all the compiler libraries), the conversion between pascal strings & C strings, and the work arounds to handle Pascal structure unions in C.
