(Note: Always search for Apple’s official build manifest if this hash is not current.)
How to check:
shasum -a 256 /path/to/your/InstallESD.dmg
If the output does not match the official hash, delete the file immediately.
If you have access to a Mac running an older OS, you can download a specific version via Terminal:
sudo softwareupdate --fetch-full-installer --full-installer-version 10.13.5
Note: Apple’s servers often redirect to 10.13.6 because 10.13.5 is no longer signed for fresh installs. If this fails, use the DosDude1 patcher tool (see below).
1. Extract the InstallESD.dmg:
2. Convert to ISO (using Terminal):
hdiutil convert ~/Desktop/InstallESD.dmg -format UDTO -o ~/Desktop/HighSierra_10.13.5.iso
This creates a .iso.cdr file. Rename it to .iso.
3. (Optional) Create a Raw Disk Image for RDR Cloning:
For a true raw disk image (sector-by-sector) to use with dd:
dd if=/dev/zero of=~/Desktop/HighSierra_RDR.img bs=1m count=7500
hdiutil attach ~/Desktop/HighSierra_RDR.img -mountpoint /Volumes/installer
sudo asr restore --source /Volumes/HighSierraInstaller/InstallESD.dmg --target /Volumes/installer --erase
Note: This requires advanced knowledge and is not for beginners.
