macOS End of Life: Every Version, and Apple's Unwritten Support Rule
Apple supports the current macOS and the two before it — as of July 2026 that means macOS 26 Tahoe, macOS 15 Sequoia, and macOS 14 Sonoma. macOS 13 Ventura reached end of life on September 15, 2025. Apple has never published this policy formally, but it has held for over a decade: when a new macOS ships each September, the third-oldest version quietly stops receiving security updates.
That unwritten rule is the most important thing to understand about macOS end of life. There is no lifecycle page, no announcement, no countdown — a Mac running Ventura today shows no banner saying its OS stopped receiving patches last September. The dates in our table are derived from when Apple actually stopped shipping security updates for each release, which is the honest way to track a vendor that publishes no dates (we label this methodology openly — see our research on how EOL dates drift).

The hardware catch: your Mac's last macOS
macOS releases drop older Macs from their hardware-compatibility list — so many Macs reach a final supported macOS long before the machine dies. A 2017 Intel MacBook that tops out at Ventura crossed into unsupported territory in September 2025 regardless of how well it still runs. With Apple's transition away from Intel complete, Intel Macs as a class are running out of supported macOS versions; if your Mac cannot install Sonoma or later, its security-update era is over.
What "supported" really means at Apple
Two nuances worth knowing. First, Apple ships full security coverage primarily for the newest macOS; the two older supported versions receive most, but historically not all, fixes. Second, Apple occasionally back-ports emergency patches to nominally dead versions when a flaw is being actively exploited — welcome, but unpredictable, and no substitute for a supported OS. Neither nuance changes the practical rule: current-or-two-back is safe, anything older is not.
If you're on an EOL macOS
- Check upgrade eligibility (System Settings → General → Software Update): many Macs on Ventura or Monterey can move to Sonoma or Sequoia free.
- If the hardware can't upgrade: for personal use, plan replacement and limit sensitive activity; browsers keep supporting old macOS a while longer, which softens but doesn't fix the exposure. For fleets, MDM should flag any Mac below macOS 14.
- Check any version in seconds with the EOL Checker, or watch upcoming drops on EOL Watch — the next macOS EOL lands each September.
Frequently Asked Questions
Which macOS versions are still supported in 2026?
macOS 26 Tahoe, macOS 15 Sequoia, and macOS 14 Sonoma. Apple's consistent (though unpublished) practice is to ship security updates for the current release and the two before it. macOS 13 Ventura fell out of support on September 15, 2025.
When did macOS Ventura reach end of life?
September 15, 2025 — the day macOS 26 Tahoe shipped and Ventura became the third-oldest release, exiting Apple's security-update window.
Does Apple publish official macOS end-of-life dates?
No. Apple publishes no lifecycle calendar for macOS. End-of-life dates are derived from when Apple actually stops shipping security updates for a release — which reliably follows the current-plus-two-versions pattern each September. endoflife.ai labels these derived dates openly as part of its accuracy methodology.
Is it safe to keep using a Mac on an end-of-life macOS?
Risk accumulates with every macOS security bulletin your version misses. The Mac keeps working, and browsers stay updated a while longer, but OS-level flaws — including actively exploited ones — remain permanently unpatched. If the hardware supports a newer macOS, upgrade; if it doesn't, plan replacement and avoid sensitive use in the meantime.
