Nick 5.0

Nick 5.0

Nick 5.0 introduces a simpler everyday experience alongside the full Advanced interface, with clearer protection status, safer remediation, and more useful incident context.

Highlights

• New Simple mode for Home, Activity, Protection, Scan, and Storage.
• One consistent protection status and actionable count across Simple Home, Activity, Advanced Overview, Smart Scan, and System Audit.
• Clear incident states: needs review, blocked, quarantined, remediation needed, resolved, and observed.
• Responsible-app attribution for behavior detections, including short helper and command chains.
• More precise download-to-shell and ransomware-behavior detections, reducing false positives from ordinary developer workflows.
• Safer file remediation: behavior-only findings and protected system executables never offer file quarantine or Move to Trash.
• Validated self-exclusion when scanning Nick's own signed app bundle.
• Improved failed-remediation explanations and separate controls for clearing incident history and learned decisions.
• Storage review in both interface modes, powered by Nick's focused cleanup engine, with an optional link to JunkYard Cleaner for deeper storage work.

Verification

• GitHub build-and-test and SonarCloud checks passed for the final attribution change.
• The complete local suite executed 789 tests: 785 passed, 4 platform-dependent tests were skipped, and 0 failed.
• Build 5052 was validated live with the app, endpoint extension, and network filter active at the same build number.
• The final responsible-app attribution fixture produced the complete app to helper to shell chain and returned to Protected after review.
• The PKG is Developer ID signed, notarized, stapled, and ready for Gatekeeper verification.

Nick requires macOS 26 or later.
