PSA: macOS 28 will drop support for encrypted Mac OS Extended volumes

Apple recently made a significant announcement regarding the upcoming macOS 28 update, which has raised concern among users who utilize encrypted Mac OS Extended volumes. According to 9to5Mac, the tech giant has stated that macOS 28 will no longer support encrypted Mac OS Extended volumes, requiring users to decrypt or reformat certain storage volumes to continue using them. This change marks a shift in Apple's approach to encryption and storage management, prompting speculation and discussion within the tech community.

Background of macOS 28 Update

macOS 28 is the latest iteration of Apple's operating system for Mac computers, set to bring new features, improvements, and security enhancements to users worldwide. With each new update, Apple aims to streamline user experience while addressing any vulnerabilities or outdated technologies that may pose risks to data security.

Apple's decision to discontinue support for encrypted Mac OS Extended volumes in macOS 28 reflects the company's ongoing efforts to enhance data protection and encryption standards within its ecosystem. While this change may initially pose challenges to users with encrypted volumes, Apple is likely introducing this update with the intention of bolstering overall system security and performance.

Implications for Users

For users who currently rely on encrypted Mac OS Extended volumes to secure their data, the news of macOS 28 dropping support for this feature can be unsettling. This change could potentially disrupt the workflow of individuals who have encrypted volumes set up for sensitive information or increased privacy measures.

While Apple has advised users to decrypt or reformat their encrypted volumes before updating to macOS 28, the process of migrating data and transitioning to alternative storage solutions may prove cumbersome for some individuals. This shift necessitates careful planning and consideration to ensure data integrity and accessibility post-update.

Security Concerns and Data Protection

The decision to discontinue support for encrypted Mac OS Extended volumes in macOS 28 raises questions about data security and protection within Apple's ecosystem. While the company may have valid reasons for this change, such as advancing encryption standards or optimizing system performance, users are understandably concerned about the implications for their stored data.

With data breaches and cyber threats on the rise, maintaining robust encryption practices and storage security is paramount for safeguarding sensitive information. Apple's adjustment to encrypted volume support in macOS 28 underscores the evolving landscape of data protection and the ongoing need for users to prioritize security measures.

Transitioning to Alternative Storage Solutions

As macOS 28 approaches its release date, users with encrypted Mac OS Extended volumes must prepare for the transition to alternative storage solutions that align with Apple's updated guidelines. Whether decrypting existing volumes or reformatting storage drives, individuals must take proactive steps to ensure a smooth migration process.

Exploring compatible encryption methods and file systems that are supported by macOS 28 will be essential for users seeking to maintain data security while adhering to Apple's new requirements. By researching and implementing suitable storage solutions in advance, users can mitigate potential data loss or complications during the update.

Feedback from the Tech Community

Apple's decision to drop support for encrypted Mac OS Extended volumes in macOS 28 has sparked conversations and debates within the tech community, with experts and users sharing their insights on the implications of this change. Some individuals view this update as a necessary step towards enhancing security protocols, while others express concerns about the impact on user convenience and data accessibility.

By engaging in constructive dialogue and feedback exchanges, the tech community can offer valuable perspectives and solutions to address the challenges posed by Apple's revised encryption policies. Collaborative efforts and shared expertise may ultimately lead to innovative approaches to data security and storage management in future operating system updates.

Guidance from Apple for Users

Recognizing the potential impact of macOS 28's encryption-related changes on users, Apple is providing guidance and instructions to help individuals navigate this transition effectively. By offering detailed steps for decrypting or reformatting encrypted volumes, Apple aims to assist users in preserving their data integrity and adapting to the new storage requirements.

Users are encouraged to refer to Apple's official communications and support resources for reliable information on preparing for macOS 28 and addressing any encryption-related concerns. Following Apple's recommendations closely can lead to a smoother update experience and ensure that users can continue utilizing their Mac systems securely.

The transition away from encrypted HFS+ aligns with Apple's broader push toward APFS, which has served as the default file system across Mac, iPhone, and iPad ecosystems for several years. Unlike Mac OS Extended, which relies on FileVault 2 layered atop the volume, APFS was designed with native encryption at its core, offering per-file and per-extent keys alongside more efficient snapshot, copy-on-write, and space-sharing capabilities. For most users, converting existing volumes to APFS before upgrading to macOS 28 should preserve data while bringing noticeable performance and reliability improvements, though Apple has emphasized that a complete backup remains essential before any disk-formatting operation.



For organizations and creative professionals managing large external archives, this change carries practical implications that extend beyond simple reformatting. Legacy workflows involving bootable HFS+ drives, older Time Machine destinations, or cross-platform shared disks will need reassessment, particularly where compatibility with non-Apple systems is required. Users can prepare by identifying encrypted volumes in Disk Utility, confirming data redundancy, and selecting the appropriate APFS scheme—standard, encrypted, or case-sensitive—based on their specific use case. While the deprecation removes yet another legacy technology from macOS, treating the migration as an opportunity to modernize storage infrastructure can help minimize disruption when macOS 28 arrives.
