Review: macOS High Sierra 10.13.5 Image File

Rating: 3.5/5 Stars

The Good: For users looking to retrograde their Apple experience, finding a working disk image of macOS High Sierra 10.13.5 is becoming increasingly difficult as Apple pushes newer macOS versions. This specific image file delivers the core promise: a functional installer for an OS that sits right on the precipice of the major design changes seen in later versions.

The 10.13.5 update was notable primarily for introducing support for iCloud Messages in the Cloud, along with the usual slate of security patches and stability improvements. If you are running this on vintage hardware (like a 2009-2011 MacBook Pro) or need it for specific software compatibility (32-bit apps still run perfectly here), this image is a vital resource.

The Experience: The download via the "hot" link provided was surprisingly brisk. Often, third-party hosting sites throttle speeds or bury the download behind six pages of deceptive "Download Now" buttons. While there were the standard captcha hurdles, the file integrity upon completion was solid—no corrupted headers or missing packages during the initial verification.

The Bad: However, this is not a perfect solution for the average user.

  1. Complexity: You cannot simply run this file. Unless you have experience with Disk Utility or terminal commands to restore the image to a USB drive, this file is useless to you. It is not a "click-and-install" upgrade.
  2. Security Warning: Downloading OS images from third-party "hot" links always carries inherent risks. While the file booted fine in testing, users should always verify the SHA-1/MD5 checksums against Apple’s official archives if possible to ensure the image hasn't been tampered with.
  3. Version Specifics: 10.13.5 is not the "final" version of High Sierra. Most users looking for High Sierra should ideally seek out 10.13.6, which was the last stable release before Mojave. Installing 10.13.5 means you will likely have to run a subsequent Software Update immediately after installation.

Verdict: If you are a power user needing to specifically restore a machine to 10.13.5, or if you are building a hackintosh setup that requires this specific kernel version, this image is a convenient find. It saves the hassle of trying to extract the installer from Apple’s fragmented legacy support pages. However, casual users looking to upgrade an old Mac would be better served hunting for the official 10.13.6 "Combo Update" directly from Apple's servers to ensure maximum security and stability.

Downloading macOS High Sierra 10.13.5 as an image file (DMG or ISO) is often necessary for users needing to perform a clean install, set up a virtual machine, or create bootable media for older Macs. While Apple primarily provides updates through the App Store, legacy installers for macOS High Sierra remain available through official and community-supported channels. Official Apple Download Methods

The most reliable way to obtain the macOS High Sierra installer is directly from Apple.

App Store Link: You can find the macOS High Sierra installer on the Mac App Store using a direct link in Safari.

Support Page Packages: Apple provides manual download links for the macOS High Sierra 10.13.5 Update and the Combo Update. These are PKG files used to update an existing High Sierra installation to version 10.13.5.

Mist Utility: For users on newer Macs (Monterey or later), the Mist tool on GitHub can bypass App Store limitations to download older macOS firmwares and installers directly from Apple's servers. Creating an Image File (DMG or ISO)

If you need a standalone image file rather than just the .app installer, you can create one manually.

Create a DMG: Use Disk Utility to create a writable disk image (roughly 6GB) formatted as Mac OS Extended (Journaled). If you are looking for an official macOS High Sierra 10

Terminal Command: Once you have the "Install macOS High Sierra.app" in your Applications folder, use the following command in Terminal to create bootable media:sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/YourVolumeName

ISO for Virtual Machines: After creating a bootable DMG or USB, you can use Disk Utility’s "Convert" feature to change the format to a CD/DVD Master (.cdr), which can be renamed to .iso for use in software like VirtualBox or VMware. Troubleshooting Common Issues

The "Tiny Installer" Problem: Sometimes the App Store downloads a small ~20MB file instead of the full ~5GB installer. To fix this, ensure you are running the latest version of macOS Sierra before downloading, or use the gibMacOS script from GitHub to fetch the full recovery or installer files.

The ".rdr" File Extension: While some older "Hackintosh" guides mention .rdr files (typically associated with older disk imaging tools like R-Drive Image), these are largely considered obsolete. Modern methods prefer standard DMG or ISO images used with tools like OpenCore.

"Hot" App: The term "Hot" in your search may refer to the Hot menu bar application, which monitors CPU thermal throttling—a common concern when running older OS versions on intensive hardware.

Are you planning to install High Sierra on a physical Mac or a virtual machine? discussions.apple.com

To download macOS High Sierra 10.13.5 or its image files, you can use official Apple links or recovery-based image formats often used in community-led projects. While Apple primarily provides the full installer via the App Store, specific file types like .rdr are used for rapid disk restoration. 1. Download via Official Apple Sources

The most secure method is to use Apple's official direct links or the App Store. Note that the App Store version usually downloads the final version (10.13.6), while specific version updates (like 10.13.5) are available as manual downloads.

Full Installer (App Store): Use the official App Store link to download the latest High Sierra installer.

Version 10.13.5 Manual Update: If you already have 10.13.4, you can download the macOS High Sierra 10.13.5 Update directly from Apple Support.

Combo Update: To upgrade from any 10.13.x version to 10.13.5, use the macOS High Sierra 10.13.5 Combo Update. 2. Understanding the .rdr Image File

A .rdr file is a proprietary disk image format used by R-Drive Image for system recovery and data restoration.

Usage: In the Hackintosh and recovery community, .rdr images are often shared to allow users on Windows to create a bootable macOS USB quickly without needing an existing Mac.

Software Needed: You must use R-Drive Image to open, read, or restore these files.

Availability: These files are not officially provided by Apple. They are typically found on community forums like Reddit's r/hackintosh or specific tech blogs, though many links for older versions like 10.13.5 may be inactive. 3. Alternative: Creating a Bootable ISO/DMG

If you cannot find a reliable .rdr file, it is safer to create your own bootable image from the official installer:

What is macOS High Sierra 10.13.5?

macOS High Sierra 10.13.5 is a significant update to the macOS operating system, released by Apple on June 4, 2018. This update brings several improvements, bug fixes, and new features to the system, including:

Downloading macOS High Sierra 10.13.5 Image File

You can download the macOS High Sierra 10.13.5 image file (build 17F35a) directly from the Mac App Store or through other reliable sources. Here are the steps:

Official method (recommended)

  1. On a Mac that can run High Sierra, open the App Store.
  2. Search for “macOS High Sierra” or use Apple’s support download page for older macOS versions.
  3. Click Download to get the macOS High Sierra installer app (Install macOS High Sierra.app) in your Applications folder.
  4. To create a bootable USB image:
    • Insert a 16 GB (or larger) USB drive and format it as Mac OS Extended (Journaled) with GUID Partition Map.
    • Use Terminal and the createinstallmedia command: 
      sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyUSB
    • Follow prompts to complete the bootable installer.

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).

  1. Go to Apple’s support page: HT208969 – but that now redirects.
  2. Use this direct App Store link (works on older Macs only):
    • macappstores://itunes.apple.com/app/id1246284741?mt=12 (High Sierra)
  3. 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: I cannot provide download links for macOS installers

hdiutil create -o HighSierra -size 8g -layout SPUD -fs JHFS+
hdiutil attach HighSierra.dmg -noverify -mountpoint /Volumes/install_build

hdiutil detach /Volumes/Install\ macOS\ High\ Sierra
hdiutil convert HighSierra.dmg -format UDTO -o HighSierra.iso

Part 1: Understanding the Request – What is “10.13.5” and “rdr hot”?

No official Apple download exists for 10.13.5 directly because Apple only keeps the latest minor version (10.13.6) on its servers. You must retrieve a 10.13.5 image via third-party archives, but extreme caution is needed.
