Open Source C++ System Software for Mac

Breakpad is an open source crash reporting system developed by Google that provides both client and server components to capture, analyze, and report software crashes across platforms. It is designed to help developers diagnose and fix crashes efficiently by generating detailed crash dumps, stack traces, and diagnostic data whenever an application fails unexpectedly. The framework includes libraries for embedding crash-handling functionality directly into applications and tools for processing and symbolizing crash dumps on the server side. Breakpad supports multiple operating systems, including Linux, macOS, and Windows, and integrates easily into existing build systems. Its flexible architecture enables developers to automate crash collection and reporting pipelines, making it a popular choice for large-scale software projects and products.

FingaMIDI is a replacement trackpad driver for G4 PowerBooks and second-generation (white) iBooks (G3 and G4) that allows the trackpad to be used as a 3-axis MIDI controller.

Advanced trackpad driver to support Apple Powerbooks and iBooks using ADB trackpads. Adds circular scrolling, scrolling areas and hotspots by running the pad in absolute mode.

Help port the tulip driver from free/net/openbsd to Darwin OS. So far the driver is written to the ADMtek 985 clone chipset and the PNIC 82c169 chipset. Due to IOKit's object-oriented design, the code can be easily subclassed to support new chipsets.

This project should bring as much as possible ZyXEL modem drivers to Mac OS X/Darwin.

fnSwitch is an application that changes the behaviour of the fn key for the new Apple PowerBooks. It allows to use function keys without the fn key.

A modified version of Apple's trackpad device driver that allows for two-finger scrolling on most Aluminum PowerBook and G4 iBook models introduced before 2005.
