Troubleshooting Common Download & Installation Issues
1. “This copy of the Install macOS High Sierra application is damaged”
- Cause: Expired certificate (Apple stopped signing 10.13.6 after November 2020).
- Fix: Set system date back to a date before the certificate expiry (e.g.,
date 010100002020 in Terminal before running installer). Or use the --allowUntrusted flag with createinstallmedia.
- Example: Search Apple’s support site for “macOS High Sierra download” and follow links to the App Store or to an Apple-provided installer package. Apple sometimes offers a “Download macOS High Sierra” link that opens the App Store to fetch the installer app.
