Apple Updates macOS 28 Guidance for Direct Encrypted HFS+ to APFS Conversion
Key points
- Apple updated macOS 28 migration guidance.
- Encrypted HFS+ volumes can now convert directly to encrypted APFS.
- Previous guidance required decryption or reformatting first.
- The new option does not apply to encrypted Time Machine backup disks.
Revised Migration Process for macOS 28
Apple has updated its support documentation for macOS 28, introducing a new method for users to convert encrypted HFS+ volumes to APFS. Previously, users with encrypted Mac OS Extended (HFS+) drives were instructed to either decrypt or reformat their volumes before migrating to APFS for macOS 28 compatibility.
Direct Conversion Now Available
The revised guidance now includes a third option: direct conversion of an encrypted HFS+ volume to encrypted APFS without requiring prior decryption. This simplifies the transition for users who rely on encrypted legacy Mac-formatted storage devices.
How to Perform the Conversion
The new process involves using Disk Utility. Users need to open Disk Utility, select the volume, and then choose 'Convert to APFS' from the Edit menu. Apple has also removed the previous instructions that detailed decrypting a volume before converting it.
Exclusion for Time Machine Backups
Apple notes that this direct conversion solution does not apply to encrypted Time Machine backup disks. Users with such backups will still need to follow alternative procedures for migration.
