  6. The newest macOS Apple lists this Mac for is macOS Sequoia; Apple’s macOS 27 Golden Gate list does not name it. endoflife.date shows Sequoia still receiving security updates on 22 September 2026. Apple’s habit of patching the two releases before the newest points to those updates ending around autumn 2027; that is an inference, not a commitment. Source: endoflife.date. Read 22 Sep 2026

  8. No earlier iMac Pro model has a recorded end to its security updates yet, so there is no precedent to show for the iMac Pro (2017).

  9. 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.
