Summary:
When making a cross-platform hybrid disk image, `hdiutil` only supports HFS+, ISO9660, ISO9660+Joliet, and UDF filesystems. Since macOS High Sierra can now be installed with APFS, it makes sense to include APFS as an argument to the `hdiutil` command.
Steps to Reproduce:
1. Open Terminal
2. `cd` into your Documents or local workspace
3. Ensure you have a folder named "project" which contains the following non-zero files:
* mac.txt
* win.txt
4. Run the following command:
`hdiutil makehybrid -o image.iso project -iso -apfs -hide-iso project/mac.txt -hide-apfs project/win.txt`
Expected Results:
A hybrid disk image file named "image.iso" is created with the ISO9660 and APFS filesystems, and presents console output similar to the following:
Creating hybrid image...
...............................................................................
Observed Results:
`hdiutil` returns an unknown option. Replacing `apfs` with `hfs` obviously succeeds, but does not generate the desired APFS+ISO9660 hybrid disk image.
Version:
10.13 beta 17A264c
Notes:
Attached is the generated HFS+ISO9660 hybrid image, and the two extracted plaintext documents, mac.txt and win.txt, which are visible only on macOS and Windows, respectively.
Configuration:
Any/All Macs running High Sierra
