I have no definitive answer about whether my Mac on macOS Sequoia has been abandoned security-wise or if it’s still receiving the latest security updates without downgrading to 26 Tahoe. Anyone actually know the answer?

@shac The most recent update for Sequoia is 15.7.4, released on February 11th, 2026. I'm still on Sonoma, which received an update to 14.8.4 on the same day. This update is shown in Software Update, but the "upgrade" to Tahoe is much more prominently features.

If these updates really contain the latest security updates or just very critical things, that's a good question...

@me_ I know I have the latest update for that OS. The question is whether Apple is issuing security updates to Sequoia or whether it is done doing that and my only option is to go to Tahoe.

For my phone they did exactly the latter, which forced me to iOS 26. There was no indication that this was the case. If I didn’t investigate I would be running an unpatched OS right now

@shac @me_ they are still issuing security updates for macOS 15 and 14, but they acknowledged like a year or two ago that they don't backport everything...

@siguza @me_ As long as the system is current on security patches, they don’t need to backport anything else. The problem is that we have no way of knowing when they’re done issuing security updates. All we can do is look at 26 updates and wait on someone to verify whether the holes they fixed are present in 15.

@shac @me_ I mean, with macOS you get the last 3 major versions. So once 27.0 (final, not beta) ships, macOS 14 is done.

But I would not be surprised if there were kernel vulns that got fixed in 26.x, but not in 15 or 14.
