How long can I put off upgrading to macOS 26? (lemmy.world)

I'm running macOS 18 and since I depend on dark mode, macOS 26 seems like a step backwards for my eye sensitivity.

So I'd like to stay on 18 for as long as it receives security updates and consider upgrade options some time later. Do the ISOs tend to remain available? Because my understanding is that when it comes to iOS, if you miss the last chance to upgrade, you're stuck with whatever you have.

What? No, Apple wants you to upgrade to the latest iOS so you can always install the latest supported version.

You can’t downgrade versions though. Once the signing window is up for the old version there’s no going back. But going forward is never a problem.

    Thanks, that solves my confusion about iOS.

    For macOS, I like to hang back a release or two. So will it be possible to upgrade to macOS 26 in 2027/28?

    Once they move on to newer versions it can be harder to find installers for previous versions, but they do continue to host them. I think you usually have to find them via a support page.
