Which of these actions should you take if an alert appears after you install a...

System extensions on macOS (e.g., kernel extensions pre-Sonoma, replaced by system extensions) may trigger alerts if they’re unsigned, blocked by Gatekeeper, or incompatible. The alert typically suggests the extension is unapproved or failed to load. The best action is to contact the developer for support, as they can provide an updated, signed version or instructions to resolve the issue.

Option A (System Information) shows extension details but can’t notarize them—Apple’s notarization is developer-side.

Option C (Migration Assistant) transfers data, not updates extensions.

Option D (Safe Mode) disables extensions but doesn’t fix the alert.

Option B is proactive and aligns with Apple’s advice. See " If a system extension won’t load " (support.apple.com/HT210999).
