Before proceeding, it is critical to state the following: macOS High Sierra 10.13.5 is no longer supported by Apple. All security updates, patches, and App Store signing certificates for this version have been deprecated. Downloading operating system files from third-party websites (especially those with cryptic "rdr hot" labels) carries significant risks, including malware, modified kernels, and disabled security features.

However, for legitimate legacy purposes (e.g., running old 32-bit software, testing on unsupported Macs, or working with vintage hardware), here is a comprehensive guide to obtaining a clean, safe image of macOS High Sierra 10.13.5. Part 2: Why You Should Probably Use 10

Part 2: Why You Should Probably Use 10.13.6 Instead

| Version | Pros | Cons | |---------|------|------| | 10.13.5 | Specific legacy software compatibility | No security patches; hard to find clean copies | | 10.13.6 | Final stable release; still available via Apple; supports all security updates | Slightly different kernel extension signatures |

If there is no absolute requirement for build 17F77, use 10.13.6. It includes every fix from 10.13.5 plus months of additional patches.

Option A: Apple’s Official (but indirect) Download – Get 10.13.6 and backdate

Apple discontinued direct High Sierra downloads in 2021, but you can still retrieve the installer via dosdude1’s patcher or a direct Apple link (if still active).

Go to Apple’s support page: HT208969 – but that now redirects.
Use this direct App Store link (works on older Macs only):
- macappstores://itunes.apple.com/app/id1246284741?mt=12 (High Sierra)
If that fails, download the InstallMacOSHighSierra.pkg from Apple’s software update server via command line:
```
curl -O https://swcdn.apple.com/content/downloads/.../InstallMacOSHighSierra.pkg
```
Note: The exact URL changes – use softwareupdate --list-full-installers in terminal on any Mac running macOS 10.14+ to fetch the latest 10.13.6 only.

Convert the official installer to an ISO/DMG:

hdiutil create -o HighSierra -size 8g -layout SPUD -fs JHFS+
hdiutil attach HighSierra.dmg -noverify -mountpoint /Volumes/install_build
sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/install_build
hdiutil detach /Volumes/Install\ macOS\ High\ Sierra
hdiutil convert HighSierra.dmg -format UDTO -o HighSierra.iso

Option C: Recovery Partition Extraction

If any Mac still has High Sierra 10.13.5 installed natively (un-updated since 2018), you can clone the recovery partition:

Boot into Recovery (Cmd+R).
Use diskutil list to find the Recovery HD.

Create a .dmg of that partition:

dd if=/dev/diskXsY of=HighSierraRecovery.dmg bs=1m

Method 2: Download from Apple Support Website

Visit the Apple Support website.
Click on "macOS High Sierra" under "Software and operating systems."
Select "How to get old versions of macOS" and follow the instructions.
