macOS 28 Will Remove Support for Encrypted HFS+ Volumes

Apple, in a new support document: In macOS 28 and later, the Mac OS Extended file system format will be supported only for volumes (disks and other storage devices) that aren’t encrypted. For future macOS compatibility, either decrypt or reformat any encrypted Mac OS Extended volumes. macOS 28 and later will continue to support unencrypted volumes that use Mac OS Extended format. Mac OS Extended is also known as HFS Plus (or HFS+). Time goes marching on.
