macOS 27 Golden Gate came out on 14 September 2026, and it does not run on Intel Macs. If you bought your Mac before late 2020, Software Update will not offer it to you. macOS Tahoe, the version before it, is the last release that supports Intel hardware at all.
That single fact has been muddled with a second, separate story about Rosetta 2, and the two keep getting tangled together online. So let me untangle them, tell you exactly which machines are affected, and explain what I'd actually do if I were still on an Intel Mac right now.
Why macOS 27 leaves Intel Macs behind
This is the cleaner half of the news. Apple said at WWDC 2025 that macOS Tahoe (macOS 26) would be the final version of macOS for Intel-based Macs, and it kept to that. macOS 27 is Apple silicon only. No Intel machine can upgrade to it.
It is the logical endpoint of a transition Apple kicked off in 2020, when the first M1 Macs arrived. Every Mac the company sells now runs on its own chips, and keeping a parallel Intel build of the operating system going was always going to have an expiry date. macOS Tahoe is that date.
macOS 27 shipped on 14 September 2026, the same day as iOS 27. That is the end of new features for Intel owners. From here an Intel Mac gets security fixes, not new versions.
Which Macs get macOS 27?
Every Mac with an M-series chip, plus the MacBook Neo:
- MacBook Air (M1, 2020) and later
- MacBook Pro (M1, 2020) and later
- MacBook Neo
- Mac mini (M1, 2020) and later
- iMac (M1, 2021) and later
- Mac Studio (2022) and later
- Mac Pro (2023)
The quickest check is the Apple menu, then About This Mac. If the first line under the name says Chip, you can install macOS 27. If it says Processor and then Intel, Tahoe is as far as your Mac goes. There is no official way to install macOS 27 on an Intel Mac, and I would not trust any tool that claims otherwise.
Which Intel Macs does this affect?
Tahoe already trimmed the list of supported Intel models heavily, so the pool of affected machines is smaller than you might think. The Intel Macs that can run macOS Tahoe, and which therefore reach the end of the road with it, are:
- 16-inch MacBook Pro (2019)
- 13-inch MacBook Pro (2020, four Thunderbolt 3 ports)
- 27-inch iMac (2020)
- Mac Pro (2019)
If you own one of these, your Mac has not stopped working. It simply stays on Tahoe. Apple said at WWDC 2025 that Intel Macs would keep getting security updates for three years, so you are covered into 2028, just without new features.
If your Mac is older than the models above, you are already off the upgrade path and this changes nothing for you today.
Rosetta 2 is a different question
Here is where most of the confusion comes from. Rosetta 2 is not about Intel Mac hardware at all. It is the translation layer that lets Apple Silicon Macs run apps that were built for Intel chips. Plenty of people on M-series Macs rely on it without ever noticing, because it works quietly in the background.
Rosetta 2 did not go away with macOS 27. Apple's support documentation says it stays fully available through macOS 27, as a general-purpose tool to give developers time to finish moving their apps over to native Apple silicon builds. So yes, Intel apps still run on macOS 27, as long as the Mac itself is an Apple silicon one.
When Rosetta actually starts to disappear
The real cutback comes with macOS 28, expected in 2027. From that point, Apple says Rosetta will be limited to certain older, unmaintained games that depend on Intel-based frameworks. General Intel apps lose translation support.
I will flag one honest wrinkle: Apple's developer release notes and its support page word this slightly differently, with the developer notes reading more like a hard cutoff and the support page describing a gentler wind-down. Apple has not published a single document that reconciles the two. The safe reading is that Rosetta does not vanish overnight, but its coverage narrows sharply from macOS 28, so nobody should treat it as a permanent fixture.
What to do if you're still on an Intel Mac
No need to panic, but now that macOS 27 is out, it is worth having a plan rather than drifting.
If your Intel Mac still does everything you need, keep using it. Staying on Tahoe with security patches is a perfectly reasonable position for the next couple of years, particularly for a machine that is mostly for browsing, mail, and office work.
If you are thinking about upgrading anyway, this is a sensible moment to do it on your own timeline rather than under pressure. The cheapest way onto Apple silicon is now the MacBook Neo at £699. If you want a desktop, the Mac mini starts at £899, and it is worth reading up on Apple's recent Mac mini pricing changes before you assume it is still the bargain it once was. For context on where Apple's chip strategy is heading, my piece on Apple's Intel chip test production is worth a look too.
If you are already on an Apple Silicon Mac and just worried about Rosetta, audit your apps now. Open Activity Monitor, check the Kind column, and anything marked Intel is running through Rosetta. Where a Universal or Apple Silicon version exists, switch to it. Where it does not, that is your cue to nudge the developer or find a native alternative well before macOS 28.
For a sense of what you would actually gain by moving to a current Mac on Tahoe, some of the newer touches are genuinely nice, like being able to set your Mac to power on without the button.
FAQ
Will my Intel Mac stop working now macOS 27 is out?
No. It stays on macOS Tahoe and keeps running normally. It cannot upgrade to macOS 27, and Apple has said it will get security updates rather than new features until around 2028.
Is Rosetta 2 going away with macOS 27?
No. Rosetta 2 is fully supported on macOS 27 on Apple silicon Macs. The significant cutback comes with macOS 28, expected in 2027, when it narrows to certain older games.
When did macOS 27 come out?
macOS 27 Golden Gate was released on 14 September 2026, for Apple silicon Macs only.
Can I install macOS 27 on an Intel Mac?
No. macOS 27 is Apple silicon only, and Apple's installer will not run on an Intel Mac. The newest version an Intel Mac can run is macOS Tahoe. I would not trust any tool that claims to get around that.
My take
The headline sounds dramatic, but the reality is gentle if you plan for it. The hardware cutoff has now happened: Tahoe is the last stop for Intel Macs, and macOS 27 is Apple silicon only. Rosetta is the slower-moving piece, with the real changes due in macOS 28 next year. If you are on Intel, treat the next twelve months as your window to upgrade on your terms. If you are on Apple silicon, spend an evening checking which of your apps still lean on Rosetta and start replacing them now.
