Summary iPlain-English security verdict for OS X, generated from its current health score, actively-exploited vulnerabilities, and latest supported version.
OS X currently scores 38/100 — high risk. No tracked vulnerabilities are currently known to be exploited in the wild. Upgrade soon — serious vulnerabilities are open and a fix usually exists.
Disclosure trend iNew CVEs published for OS X each year (NVD). A higher bar means more disclosures that year — more scrutiny, not necessarily less safe.
Patch priority — what to act on iThe issues to fix first — actively exploited (CISA KEV) first, then by exploitation probability (EPSS), then severity. Each row's "→ fixed in" is the earliest version that patches it; "see advisory" means no fixed version is published.
Most urgent first — actively exploited, then likeliest to be exploited.

Why is OS X listed on IsItPatched?
OS X was added automatically because CISA's Known Exploited Vulnerabilities (KEV) catalog flagged it as actively exploited in the wild. IsItPatched tracks its known CVEs, severity (CVSS), exploitation probability (EPSS) and KEV status from public data; its version and lifecycle mapping is verified over time.
