Native macOS development with AppKit, Catalyst, and macOS-specific APIs. Use when building Mac-native apps, menu bar apps, system extensions, or macOS-specific features.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# macOS Native Development
Comprehensive guide for building native macOS applications with AppKit and modern macOS APIs.
## Framework Overview
| Framework | Use Case | Notes |
| -------------------- | -------------------- | --------------------------- |
| **AppKit** | Traditional Mac apps | Full control, mature |
| **SwiftUI** | Modern Mac apps | Cross-platform, declarative |
| **Catalyst** | iPad apps on Mac | Quick port, limitations |
| **AppKit + SwiftUI** | Hybrid approach | Best of both worlds |
---
## AppKit Fundamentals
### Application Structure
```swift
// AppDelegate.swift
import Cocoa
@main
class AppDelegate: NSObject, NSApplicationDelegate {
var mainWindow: NSWindow?
func applicationDidFinishLaunching(_ notification: Notification) {
setupMainWindow()
setupMainMenu()
}
func applicationWillTerminate(_ notification: Notification) {
// Cleanup
}
func applicationShouldTerminateAfterLastWindowClosed(_ sender: NSApplication) -> Bool {
return true
}
private func setupMainWindow() {

How to install
mdr add travisjneuman/.claude/macos-native@sha256:449ca5542663dc1aThe line at the top of this page pins the label git:20260113.90b2d6e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
