macOS (operating system)

macOS is a series of proprietary operating systems developed by Apple for their own hardware. It's designed exclusively for the Apple ecosystem, providing users with a powerful and user-friendly platform to operate their devices.

Early Access Feature

At the moment, support of macOS in AUI Framework is in early stage and lacks a lot of features.

macOS shares its XNU kernel and codebase with iOS (operating system).

Due to closed nature of Apple platforms, a single macOS machine is considered as the only option for AUI/application development for all supported platforms at once: - macOS - natively (obviously) - iOS - natively (via Xcode) - Android - natively (via Android Studio) - Windows - via VM - Linux - via VM - Emscripten (WebAssembly) - natively

Key considerations

• You'd want to support both architectures - x86_64 and Apple Silicon arm64 by producing universal binaries
• Application menu is located in system's top bar instead of being inside the window
• macOS hardware offers high density displays (marketing name: Retina), so you need to use density-independent dimension units such as _dp
• Apple laptops include high quality touchpads with high resolution scroll and possibility for multitouch gestures

AUI implementation specifics

• macOS launches only one instance of a bundle by itself (unless started with open -n or the executable is run directly). Clicking the Dock icon while the application is running without windows emits AApplication::activated (Application lifetime & instancing).
• Cmd+Q does not call exit(): the main loop is stopped and control returns to aui_main, so destructors and cleanup of your AUI_ENTRY run normally.
• The app does not terminate when the last window is closed if it is held with AApplication::hold or AApplication::quitOnLastWindowClosed is disabled.
