Installing macOS High Sierra (10.13) remains a common necessity for users maintaining older Mac hardware or setting up virtual machines. While Apple has moved toward newer releases, you can still obtain the official installer to create a bootable drive or perform a clean install. 1. Where to Download the macOS High Sierra Installer
There are several official and reliable third-party ways to get the "Install macOS High Sierra.app" or a DMG file:
Official App Store Link: You can often find a direct link on the Apple Support page that opens the App Store directly to the High Sierra download page.

Mist Utility: A popular open-source tool called Mist (macOS Installer Super Tool) allows you to download specific macOS firmwares and installers directly from Apple without compatibility restrictions.
Legacy DMG Links: For some older versions, Apple provides a direct disk image (.dmg) file. Once downloaded, you must double-click the DMG and then run the .pkg file inside to extract the actual "Install macOS High Sierra" app into your Applications folder. 2. Preparing Your Installation Media

Here’s a concise guide covering macOS High Sierra DMG download and installation.
What it is
- macOS High Sierra (10.13) is a macOS release focused on stability and the APFS file system, Metal 2 graphics, and HEVC/HEIF media support.
Before you begin
- Backup: Create a full backup (Time Machine or clone) of your Mac.
- Compatibility: High Sierra supports Macs from late 2009–2010 onward depending on model; verify your Mac model and hardware requirements.
- Free space: Allow at least 20–25 GB free for download and installation.
- Power: Plug into power for laptops.
Obtaining the installer (DMG vs. App Store)
- Apple distributes macOS installers via the App Store as an app (“Install macOS High Sierra”) or as a recovery image; Apple does not provide an official DMG download for end users.
- If you need an installer file:
- Preferred: Download “Install macOS High Sierra.app” from Apple’s support/downloads site or the App Store on a compatible Mac, then create a bootable installer.
- Alternate sources: Third-party DMG/ISO downloads exist online but carry security risks (tampering, malware). Avoid unofficial copies unless you trust the source and verify checksums/signatures.
Creating a bootable USB installer from the App Store app
- Download “Install macOS High Sierra.app” to the Applications folder.
- Prepare a USB flash drive (at least 16 GB) and erase it in Disk Utility as Mac OS Extended (Journaled) with GUID partition map, named "MyVolume".
- In Terminal run:
sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume - Enter admin password and confirm; wait for the process to finish.
Installing High Sierra
- From the running macOS: Open the installer app and follow on-screen prompts.
- From bootable USB: Restart Mac while holding Option (Alt), choose the USB installer, use Disk Utility to format/partition if needed, then run the installer.
- Follow prompts to complete installation; the Mac may reboot several times.
Verifying and troubleshooting
- Internet Recovery: If the internal drive is problematic, Internet Recovery (Command+Option+R) can reinstall the macOS version that came with the Mac or the latest compatible.
- File system notes: Upgrading a compatible SSD will convert its format to APFS automatically; APFS is not used for Fusion Drives or older HDD setups in High Sierra.
- If installer fails: check free disk space, run First Aid in Disk Utility, disconnect third-party peripherals, reset NVRAM/SMC, or reinstall from macOS Recovery.
Security and integrity
- Prefer official Apple downloads; verify installer via macOS built-in checks (Gatekeeper) and avoid running unknown DMG images.
- After installation, apply all available security updates via Software Update.
If you want, I can:
- Provide exact Terminal commands for verifying installer checksums.
- Walk through creating a USB installer step-by-step for your Mac model.
- Explain how to check compatibility for your specific Mac (tell me your model/year).
