1. Trust is Impossible (1/5 Stars) You are downloading a system-level disk image from a public Google Drive folder. Unless the file has a verified SHA-256 checksum matching Apple’s official release, you have no idea what is inside. Keyloggers, cryptominers, or modified system files are common payloads in unverified OS DMGs.
2. The “Damaged” Error Loop Even if you find a clean DMG, High Sierra has a notorious “Gatekeeper” issue. Because the certificate on the installer expired in 2019, macOS will flag any copy downloaded today (even from Google Drive) as “damaged.” You have to manually change your system date in Terminal to install it. Most Google Drive copies do not include these instructions, leading to hours of frustration.
3. Bloatware & Adware Risks Many Google Drive links for this file are hosted by ad-driven forums (e.g., “Mr. Macintosh,” random tech blogs). The DMG itself might be fine, but the download process often involves clicking through three malicious ad walls, fake “Download” buttons, and browser hijackers before you actually get the 5.2GB file.
4. Missing Recovery Partition
When you use a third-party DMG from Google Drive (rather than the official createinstallmedia method), you frequently end up with a bootable OS but a broken Recovery HD partition. That means if your disk fails later, you cannot use Internet Recovery or local recovery tools.
Official Source (Recommended): The safest way to obtain High Sierra is through Apple's official servers. While it may not appear in a standard search on the App Store, Apple provides a hidden support page link (HT201372) that redirects to the Mac App Store to download the official installer. This ensures the file is cryptographically signed and safe. --- Macos High Sierra 10.13.6 Dmg Google Drive
Unofficial Source (Risk): Google Drive links are user-generated content. If you must use a third-party link, it should ideally be from a reputable tech forum or a trusted community member, and the file's checksum (SHA/MD5) should be verified against known official values to ensure the file has not been tampered with.
Once you download the DMG from Google Drive, never open it directly without verifying its SHA-1 or MD5 checksum. Use Terminal:
shasum -a 256 /path/to/your/downloaded.dmg
A legitimate macOS High Sierra 10.13.6 DMG (build 17G14042) will return:

Note: This hash is for the final combo installer. Always double-check official Apple references or trusted Apple developer forums.
If your Mac originally shipped with macOS Sierra or earlier, 10.13.6 will work fine. However, if you have a 2012 or newer Mac, consider Mojave or later for better app support. Do not force-install High Sierra on unsupported hardware (e.g., a 2009 Mac Pro without a metal-capable GPU).
