Skint
Skint is a free macOS utility from Howard Oakley that checks key Mac security settings and update status, then reports issues with simple alerts.
What is Skint?
Skint is a lightweight Mac security utility that helps users monitor important protection settings and security data on their Mac. It focuses on checks such as System Integrity Protection, the Signed System Volume, Gatekeeper, XProtect, XProtect Remediator, and macOS security update status, then presents the results in a simple traffic-light style summary. Users can open it for an on-demand review or leave it running so it refreshes its checks roughly once every 24 hours. Skint is aimed at Mac users who want a clearer view of whether core built-in protections are active and current without digging through system tools. It works as a companion to other Mac security utilities from Howard Oakley and is designed for recent versions of macOS.

Safety overview
Status: Mostly safe
Skint is a legitimate Mac utility for checking built-in security protections and update status. Its system access is consistent with that purpose, and leaving it running is normal if you want regular daily checks. Because it reports on security features rather than changing them for you, the main practical risk is misunderstanding a warning and making unnecessary system changes. Treat alerts as prompts to review your Mac's security state carefully rather than as reasons to modify settings immediately.
Recommendation: Keep Skint if you use it to monitor your Mac’s security health or want lightweight daily checks in the background. If you do not use its reports or already rely on other tools for the same job, you can remove it without affecting normal macOS operation.
