End of HFS+ Encrypted Volumes in macOS 28
Apple’s ongoing commitment to refining its operational frameworks is evident as it prepares for the release of macOS 28 in the fall of 2027. This new operating system will introduce significant changes, including the discontinuation of support for encrypted HFS+ (Mac OS Extended) volumes, compelling users to reconsider their data management strategies.
The Transition from HFS+ to APFS
For many users, HFS+ has been the bedrock of file management on macOS for years. However, the upcoming macOS 28 will only support unencrypted HFS+ volumes. This change means that anyone utilizing encrypted HFS+ volumes will need to transition their data to a different file system. Apple’s more robust APFS (Apple File System) has gradually replaced HFS+, offering better performance and security—especially on SSDs.
What Users Need to Know
Users who rely on HFS+ encrypted volumes, particularly for backups or archived files on external drives, will face an urgent need to migrate. Without this action, their files will remain inaccessible after upgrading to macOS 28. The good news is that both encryption and decryption processes can lead to data loss, especially when switching file systems directly. Therefore, it is crucial to have a solid migration strategy in place.
Recommended Migration Strategies
Backup First
Before taking any steps, it’s vital to create a backup of all essential files. This ensures that, in case of any mishaps during the migration process, your data remains secure.
Directly Migrate to APFS
Instead of simply decrypting your HFS+ volume, it is advisable to format your drives directly to APFS. Migrating from an encrypted HFS+ volume to APFS Encrypted is usually more efficient than going through an HFS+ decryption phase. This one-step approach reduces the time and complexity involved in managing files.
Combining Older Drives
Users may find it beneficial to consolidate several old drives into a single larger APFS-formatted drive. However, with pricing for SSDs and HDDs fluctuating, investing in new hardware may be necessary, albeit costly.
Final Thoughts
As Apple makes this significant transition, the end of encrypted HFS+ volumes not only signifies an evolution in file management but also poses a challenge for existing macOS users. The imperative for timely preparation cannot be overstated. By efficiently managing backups and transitioning to APFS, users can ensure that their data continues to be secure and accessible, aligning with Apple’s modern standards.
