macOS 14 Sonoma Drops HFS+ Support, Ending Era for Older File System
Apple's upcoming macOS 14 Sonoma update will officially discontinue support for the Hierarchical File System Plus (HFS+), marking the end of an era for the file system that has been in use for decades. This change is part of a broader shift by Apple to phase out support for older technologies as it transitions to more modern systems. The removal of HFS+ support means that Macs will no longer be able to natively read or write to drives formatted with this older file system. Users who still rely on HFS+ will need to migrate their data to Apple's current standard, APFS (Apple File System), before upgrading to macOS 14. This transition is expected to affect older external drives and potentially some legacy internal storage configurations. Apple has been gradually moving away from HFS+ since the introduction of APFS with macOS High Sierra in 2017. The company has encouraged users to adopt APFS, which offers enhanced security, performance, and features like space sharing and snapshots. The deprecation of HFS+ aligns with Apple's strategy of streamlining its operating systems and focusing on future-proof technologies. This move also coincides with other significant changes in macOS 14, such as the removal of Intel processor support and the cessation of the ability for Apple Silicon Macs to run Intel applications.
The deprecation of HFS+ by Apple in macOS 14 represents a strategic move to consolidate its file system infrastructure around APFS. This transition, while potentially disruptive for users with legacy storage, aligns with broader industry trends towards more robust, secure, and feature-rich file systems optimized for modern hardware and software ecosystems. From a systems perspective, maintaining support for older file systems can increase complexity and security vulnerabilities. By sunsetting HFS+, Apple can streamline development, enhance security, and ensure better performance for its user base, particularly on Apple Silicon architecture. This decision also anticipates future technological shifts, where APFS's advanced capabilities are better suited for evolving storage needs and data management paradigms in the AI era.
