苹果给出了设计模板，把1024分辨率的原始图放入以后可以批量生成符合苹果标准的图标。

Start with the Apple Human Interface Guidelines and design resources linked in the issue, then locate the current macOS application icon assets in the repository. Done means updating those assets to follow Apple's sizing standards and confirming the icon no longer appears oversized when switching applications.
