I was able to get it to work on Sierra.

The issue was some missing symbols (_kDMMediaTypeCDROM and _DIHLGetBundleSize), which are only found in old frameworks. So just copy them over and use install_name_tool to load them instead.

1. Run the script as above.

2. Re-download the package and mount them:

curl -ORL http://swcdn.apple.com/content/downloads/21/09/031-20634/8d84o1ky5gn2agnf5kiz9eed134n7y3q4c/RecoveryHDUpdate.pkg

xar -xf RecoveryHDUpdate.pkg

hdiutil attach -nobrowse RecoveryHDMeta.dmg
hdiutil attach -nobrowse "/Volumes/Recovery HD Update/BaseSystem.dmg"

3. Copy over DiskManagement.framework and DiskImages.framework from

/Volumes/OS X Base System/System/Library/PrivateFrameworks

to

/tmp/DU1010/Disk Utility (10.10).app/Contents/Frameworks

4. Use install_name_tool to change where to look for those shared libraries (use otool -L in before/after to confirm that paths are really changing).

cd "/tmp/DU1010/Disk Utility (10.10).app/Contents/MacOS"
install_name_tool -change /System/Library/PrivateFrameworks/DiskManagement.framework/Versions/A/DiskManagement @executable_path/../Frameworks/DiskManagement.framework/Versions/A/DiskManagement Disk\ Utility
install_name_tool -change /System/Library/PrivateFrameworks/DiskImages.framework/Versions/A/DiskImages @executable_path/../Frameworks/DiskImages.framework/Versions/A/DiskImages Disk\ Utility

Doesn't work. Under 10.13.6, it won't even start.

on 10.14.6
