Downgrade macOS Mojave to High Sierra - Obsolete

Obsolete guidance

This article is obsolete for current AIQ documentation. Downgrading macOS Mojave to High Sierra is not current AIQ installation guidance and should not be recommended as a standard troubleshooting path.

Current recommendation

Use a macOS version supported by the target AIQ release.
Review current AIQ install guides and system requirements before changing the operating system.
Coordinate OS changes with the customer’s IT or device management team.
Prefer supported browser/runtime/configuration fixes over OS downgrades.

Disposition

Flag this page for deletion or archival unless a customer-specific legacy environment still requires it. If retained, label it clearly as historical and not current installation guidance.
