disk_kit_macos 1.2.1

macOS platform implementation for DiskKit using native macOS APIs.

1.2.1

• Preserve AppleDouble ._ companion files during recursive copies. Use POSIX directory enumeration because Foundation silently hides recognized companions, causing literal backup inventories to lose files even when copy calls succeed.
• Avoid reserializing native extended attributes when a literal AppleDouble companion is present, so restoring to filesystems without native xattrs does not create a competing companion. Metadata remains in the preserved sidecar. Verify copied file existence and size before emitting completion.
• Add native regression coverage with generated AppleDouble metadata in both serial and parallel modes.

1.2.0

• Copy directories with at most four concurrent file workers by default; parallel: false uses one worker. Run independent disk operations on a concurrent background queue while preserving per-disk exclusion.
• Report file start/completion through operation-correlated fileCopyProgress method-channel events; remove callbacks when the operation future finishes.
• Drain active workers before returning errors, retain partial output, preserve nested symlinks, and apply directory metadata after descendants.
• Reject existing copy destinations, including dangling symlinks. Copies still never merge or overwrite and have no chunk progress, in-flight cancellation or checksum verification.
• Require platform interface 2.0.0; extend native, transport and public example tests without formatting real disks.

1.1.0

• Map the additional APFS/HFS+ variants to native diskutil formats and reject MBR for both APFS variants.
• Require platform interface 1.1.0 and update the example format selector.

1.0.0

• Add raw IMG / USB-compatible hybrid ISO writing with optional read-back verification.
• Add Windows UEFI installation media preparation, including preflight FAT32 checks and optional oversized WIM splitting with caller-installed wimlib.
• Add macOS installation media preparation from an Apple-signed installer app.
• Add typed media stages and progress callbacks; allow system administrator authorization for raw writing and macOS installers.
• Update both examples, documentation, and explicit opt-in media tests.
• Require platform interface 1.0.0 and link Security with CocoaPods and SwiftPM.

0.0.1

• Implement Disk Arbitration discovery callbacks and volume operations, with IOKit initial enumeration.

• Add native file/directory copies and external formatting through diskutil.

• Add automatic Dart registration, native errors, and a public API example for macOS 12+.

• Add volume renaming and typed DiskInfo results for mount, unmount, and rename operations.
