  6. This is endoflife.date’s cycle end for Big Sur, not necessarily the day of Apple’s last patch. The newest macOS Apple lists this Mac for is macOS Big Sur. endoflife.date records security updates for Big Sur as ended on 2 February 2026. Source: endoflife.date. Read 22 Sep 2026

  7. No earlier iMac 27-inch model has a recorded end to its security updates yet, so there is no precedent to show for the iMac (Retina 5K, 27-inch, Late 2014).

    ↩

  8. An inference from Apple’s past releases, not a commitment from Apple, which publishes no date when a Mac stops getting macOS or security updates. A Mac missing from a new macOS compatibility list is not supported by that release; this page changes when that list does.
