- Fixed an issue where embedded HFS+ info was not output when a block is unexpectedly not all zeros.
July 28, 2023:
- Bug fixes.
May 20, 2023:
- Added 64-bit VSDB volume id to Volume UUID conversion for HFS and HFS+ partitions.
Dec 2, 2022:
- Fixes for Mac OS X 10.4 Tiger.
- Added the following (related to Mac booting from Open Firmware or EFI):
- Apple Partition Map
- APM Patch Driver
- HFS/HFS+ Boot Blocks
- HFS Wrapper
- HFS Master Directory Block
- HFS+ Volume Header
chosen,aliasesoptions(was previously output only for Intel Macs)
- Pass a disk name (e.g.
disk0) or a disk slice (e.g.disk0s2) to reduce the output to a single drive or partition.

Notes
Run the command before and after making partition changes. Use a different file name each time. This way you can compare the files to see what changed and to make sure the changes are correct.
This script does not list boot files. Do that manually for each partition you think should be bootable. The boot code in a VBR (also know as PBR) should show what file it's looking to boot. For Windows 7 and later, it should be BOOTMGR. That file should exist in the root directory with a Boot folder containing a BCD folder containing a BCD file. The BCD file contains a menu of items to be bootable and boot options. Use EasyBCD.exe to edit the BCD of any partition. The files may be invisible in macOS - type Command-Shift-Period to show invisible files in the Finder.
