Preparing for the Update
Apple has announced a significant change for Mac users. Starting next year, macOS 28 will no longer support encrypted Mac OS Extended (HFS+) volumes. This means external drives using this older encryption method will need attention before the update. Users must decrypt or reformat these drives to maintain access.

Users with encrypted HFS+ external drives face a clear task. They must either decrypt the drive entirely or reformat it. Reformatting will erase all data, so backing up is crucial. Decryption will remove the encryption layer, making the data accessible without the old macOS support.
What Does This Mean for My Data?
This change primarily affects older external storage devices. Many newer drives already use APFS, Apple's current file system. APFS offers robust encryption features that will continue to be supported.
The primary concern for users will be data access. If an encrypted HFS+ drive is not prepared, it may become unreadable after upgrading to macOS 28. This could lead to data loss if proper steps are not taken beforehand. Apple's support document aims to give users ample time to migrate their data or reconfigure their drives.
This decision reflects Apple's ongoing efforts to modernize its operating system. It also pushes users towards more secure and efficient storage solutions. The transition period is designed to minimize disruption for affected users.
Frequently Asked Questions
What is Mac OS Extended (HFS+)? Mac OS Extended, or HFS+, is an older file system used by Apple. It was the default for macOS until APFS was introduced. Many external drives still use this format.
Will all my external drives stop working? No, only external drives that are both encrypted and formatted with Mac OS Extended (HFS+) will be affected. Unencrypted HFS+ drives or drives formatted with APFS will continue to function normally.
What should I do if I have an affected drive? You should back up all data from the drive immediately. Then, you can either decrypt the drive or reformat it to APFS. Apple provides tools within macOS to perform these actions.
