MonitorControl is a macOS menu-bar utility that controls external displays' brightness, contrast, and volume. It does not just send one kind of command; it uses multiple control paths: hardware DDC/CI over IOKit I2C on Intel Macs, DDC/CI over IOAVService on Apple Silicon, Apple's private DisplayServices API for Apple/Thunderbolt displays, gamma-ramp adjustments for software dimming, and transparent shade windows for virtual displays. User input flows from native media keys, custom keyboard shortcuts, and menu-bar sliders into a DisplayManager singleton, which coordinates native OSD overlays, smooth brightness transitions, and cross-display synchronization. The app uses Sparkle for updates, SimplyCoreAudio for audio device handling, MediaKeyTap for media-key interception, and KeyboardShortcuts for user-defined bindings. Architecturally, this is a classic Cocoa application with a storyboard-based preferences UI, a login helper app (MonitorControlHelper), and a clean separation between models (Display, AppleDisplay, OtherDisplay), support services (DisplayManager, DDC backends, OSD utilities, media-key handling), and view controllers for preferences and onboarding. Entry points are main.swift, AppDelegate, DisplayManager, and MenuHandler. Persistence is UserDefaults backed through a PrefKey enum, and the UI is localized into 19 languages. There is no data/research component; this is purely an end-user utility. The codebase is modular and well organized, with the DDC communication isolated into Intel and ARM backends and display-specific logic abstracted behind a base Display class. It is actively maintained, with recent commits and a modern dependency setup. Technical drift is medium rather than low because much of the functionality depends on private or undocumented macOS APIs (DisplayServices, CoreDisplay, OSDUIHelper) and the code contains many macOS-version-specific workarounds, but the project tracks current macOS releases and continues to update its fallbacks.
This repository is an educational companion to the book 'Programming with 64-Bit ARM Assembly Language', adapted for Apple Silicon (ARM64 macOS, iOS, watchOS, tvOS). It contains 16 chapters of progressively complex assembly examples, covering system calls, memory addressing, functions, floating-point, NEON, and optimization. The code demonstrates key differences between Linux and Darwin (Apple) ABIs, such as syscall numbers, addressing modes (ADRP/ADD vs LDR =symbol), and variadic function calling conventions. It includes reusable debug macros (printReg, printStr) for register inspection, file I/O macros, and a toupper function callable from C, Python, and Swift. The project also features an Xcode SwiftUI app that integrates assembly code across multiple Apple platforms. The repository is well-maintained and actively used as a reference for Apple Silicon assembly development.
Free-NTFS-for-Mac is a macOS desktop utility that provides read-write access to NTFS-formatted drives using ntfs-3g and MacFUSE. It is implemented as an Electron application with a main process (Node.js) and a renderer (Chromium), offering a graphical interface for device detection, mounting, unmounting, ejecting, and resetting NTFS volumes. The application also includes a system tray mode, automatic mount on device insertion, password management via macOS Keychain, dependency checking (Homebrew, MacFUSE, ntfs-3g, fswatch), and multi-language support (English, Japanese, Chinese, German). The codebase is modular, with separate modules for device detection (event-driven via fswatch with fallback polling), mount operations, sudo execution, caching, and batch command execution. It also provides a set of shell scripts (ninja tools) for building, packaging, and installing dependencies. While the application is functionally complete and actively maintained, it exhibits some technical debt such as duplicate implementations, hardcoded paths, and reliance on system tools that may change across macOS versions.
