macOS 27 and Rosetta 2: Will Your Intel Apps Work?

There’s a lot of confusion about Rosetta 2 and macOS 27, so here’s the clear version: your Intel apps still work. macOS 27 Golden Gate is the last macOS release with full Rosetta 2, which means Intel-compiled apps keep running on Apple Silicon Macs throughout 2026. The real deadline is a year out, with macOS 28.

The Intel-Mac cutoff and the Intel-app cutoff are two different things.

#Does Rosetta 2 Still Work in macOS 27?

Yes, fully. This is the part that gets mixed up most often, so it’s worth stating plainly: macOS 27 keeps Rosetta 2 working at full capability.

Your Intel apps launch and run as before.

Rosetta 2 is the translation layer that lets apps built for Intel chips run on Apple Silicon. It has nothing to do with whether your Mac is Intel, it’s about whether your apps are. According to TechRepublic, macOS 27 is the last version to ship with full Rosetta 2 functionality, so Intel-compiled software continues to run normally on M-series Macs through the macOS 27 cycle.

#Why People Confuse the Two Cutoffs

The mix-up is understandable. macOS 27 made two Intel-related announcements at once, and they sound similar but mean different things.

One is about hardware, the other about software.

The hardware change is that Intel Macs can’t install macOS 27 at all, which is covered in our macOS 27 Intel Mac guide and the compatible Macs list. The software side is Rosetta 2, which runs Intel apps on Apple Silicon Macs. macOS 27 ends the first and keeps the second. So an M1 or M2 Mac running macOS 27 still runs your old Intel apps just fine.

#When Does Rosetta 2 Actually Stop?

The real deadline is macOS 28, expected in fall 2027. That’s when Rosetta 2 largely goes away.

A year of runway remains.

TechTimes covers the cutoff in detail. It found that more than 18,000 Intel-only Mac apps stop working in macOS 28, the never-updated holdouts that no developer recompiled for Apple Silicon. If an app you depend on is Intel-only and never gets an update, macOS 28 is the version where it stops, not macOS 27. That gives you roughly a year on macOS 27 to find replacements or push developers for native builds.

#The Exception for Older Games

Apple carved out one exception, and it’s aimed squarely at gamers. Even after macOS 28 retires most of Rosetta 2, a narrow subset survives.

Old games get a reprieve.

Per Apple’s own platform guidance, a limited part of Rosetta stays available specifically for older, unmaintained gaming titles that rely on Intel-based frameworks. So a classic Intel-only Mac game has a better chance of surviving past 2027 than an abandoned Intel-only productivity tool. It’s a small carve-out, but it matters if your library leans on older titles that no developer is going to recompile.

#How to Find Your Intel Apps Now

You don’t have to wait to see which apps are affected. macOS already tells you.

MacRumors confirms that macOS 26 Tahoe began showing a warning each time you open an app that won’t work once Rosetta 2 support ends. When we tested this on an M2 Mac, the prompt appears the first time you launch an affected Intel app, which makes the at-risk apps easy to spot well ahead of the deadline.

The smart move is to note which of your daily apps trigger the warning, then check whether a native Apple Silicon version exists. Most mainstream apps already ship as universal binaries, so in practice the warning usually flags older or niche software rather than anything you use constantly.

#What This Means If You’re Upgrading

Put simply, Rosetta is not a reason to delay macOS 27. The translation layer you rely on today comes along for the ride.

Your upgrade decision shouldn’t hinge on it.

In our testing of Rosetta 2 across M1 and M2 Macs over the past few years, the overwhelming majority of Intel apps already ran cleanly through it, and that doesn’t change in macOS 27. The honest planning horizon is macOS 28 in 2027, so treat the next year as lead time to replace any Intel-only holdouts, not as a reason to stay on macOS 26 now. The full release picture is in our macOS 27 Golden Gate features guide.

#Bottom Line

If you’re upgrading to macOS 27, your Intel apps keep working, so there’s no need to hold back over Rosetta. The compatibility you have today carries through the entire macOS 27 cycle.

The clock that matters is macOS 28 in 2027. Use the next year to identify your Intel-only apps with Tahoe’s built-in warnings, then line up native replacements before the real cutoff. Our macOS 27 release date timeline tracks the rollout.
