The system architecture of macOS includes hardware abstraction layer, XNU core, I/OKit, core services and Aqua user interface. Core components include the startup process, the APFS file system, and SystemIntegrityProtection. Performance optimization and best practices involve hardware configuration, software setup, and development skills.

macOS and Linux have their own advantages in compatibility and user experience. macOS has excellent compatibility within the Apple ecosystem, and the user experience is simple and intuitive; Linux has outstanding hardware compatibility and software flexibility. The user experience varies from distribution to distribution, emphasizing personalization and control.

When you open PyCharm for the first time, you should first create a new project and select a virtual environment, and then be familiar with the editor area, toolbar, navigation bar, and status bar. Set up Darcula themes and Consolas fonts, use smart tips and debugging tools to get more efficient, and learn Git integration.

Cross-platform development in C is recommended to use VisualStudioCode, CLion and QtCreator. 1. VisualStudioCode is lightweight and flexible, suitable for multi-platform development, but the initial configuration is more complicated. 2. CLion integrates CMake, suitable for cross-platform projects, but licenses are expensive. 3.QtCreator supports cross-platform development, with built-in Qt library, but the learning curve is steep.
