apple/container, Container Machine 기능 추가

Apple's Container Machine (WWDC26) enables macOS developers to run persistent, isolated Linux environments that seamlessly integrate with native macOS tools and workflows, eliminating friction in cross-platform development. By combining container efficiency with VM persistence and automatic home directory sharing, developers can test multiple distributions and projects without dependency conflicts or context-switching overhead. This represents a fundamental shift toward treating Linux development as a natural extension of macOS rather than a separate virtualized environment.
