macOS 27 will cut off all Intel Macs — here’s exactly what that means for you

With macOS 26 Tahoe now confirmed as the final release for Intel hardware, the clock is officially ticking. Here’s a clear-eyed look at who’s affected, what happens next, and how much runway you actually have.

Apple made it official at WWDC 2025: macOS 26 Tahoe, released in September 2025, is the last version of macOS that will ever run on an Intel-based Mac. When macOS 27 arrives — expected in beta this June and widely released in September 2026 — only Macs with Apple Silicon inside will be eligible to upgrade.

For the millions of users still running capable Intel machines, this moment has been visible on the horizon since Apple announced its chip transition back in 2020. Now it’s no longer on the horizon. It’s here.

Which Intel Macs are affected?

Not every Intel Mac made the cut even for macOS 26 Tahoe — Apple had already begun narrowing compatibility in prior releases. The four Intel models that do run Tahoe will find macOS 27 to be their final wall.

It’s worth noting that Intel MacBook Air and Intel Mac mini models didn’t even make it to Tahoe — those were dropped in earlier macOS releases. The four machines above represent the last Intel survivors, and macOS 27 ends their road.

What actually happens to your machine?

Being unable to upgrade to macOS 27 does not mean your Mac stops working. That point is worth emphasising clearly, because headlines about “obsolescence” can obscure what actually changes in practice.

What you will lose is access to new features: any capabilities Apple introduces in macOS 27 and beyond — improvements to Apple Intelligence, Siri upgrades, new system apps, performance optimisations — will not come to Intel hardware. The gap between Intel and Apple Silicon Macs, already significant with features like Apple Intelligence requiring dedicated neural hardware, will only widen with each passing release.

The Rosetta 2 question

There’s a related but distinct concern for Apple Silicon users: Rosetta 2, the translation layer that allows Apple Silicon Macs to run apps originally built for Intel processors. Apple has signalled that Rosetta 2 support is expected to end around macOS 27 or macOS 28, meaning developers are under increasing pressure to ship native Apple Silicon builds of their apps. For most mainstream software this is already done; for niche or legacy tools, it may become a problem.

A timeline of the transition

Should you upgrade now?

The honest answer depends on how you use your machine. A 2019 MacBook Pro or 2019 Mac Pro is still a capable computer for video editing, development, and everyday work in 2026. Being on macOS 26 does not change that today.

The pressure to upgrade is real but not urgent. If your workflow relies on future macOS features, or if you plan to use Apple Intelligence capabilities, Apple Silicon is now the only path forward. If your current setup works well, the security runway through 2028–2029 gives you time to make a considered decision rather than a forced one.

Apple’s transition has taken six years from the first M1 Mac to the point where the platform fully leaves Intel behind. For most users, that’s been enough time. For those still holding on — the end date is now clearly written on the calendar.
