If you have opened an older app recently and seen a new warning about it not working in a future version of macOS, you are not imagining it. Apple started showing that message in macOS Tahoe 26.4, and it is the first real, user-facing sign that Rosetta 2's long runway is starting to narrow.

The short version: nothing changes today. But there is now a real date attached to when it will, and it is close enough to plan around rather than ignore.

Short answer

Yes, Rosetta 2 is fully supported right now, on macOS Tahoe (26.6) and through the upcoming macOS 27 "Golden Gate" release expected in September 2026. Apple has confirmed that macOS 28, expected in fall 2027, is when general-purpose Rosetta 2 support ends, kept alive afterward only for a narrow set of old game titles and Intel code inside Linux virtual machines. If you rely on an Intel-only app, you have roughly a year and a half from today to find a native replacement or a workaround, not an emergency, but not indefinite either.

What Rosetta 2 Actually Does

Rosetta 2 is the compatibility layer Apple built for the 2020 transition from Intel chips to Apple Silicon. When you launch an app compiled only for Intel processors on an M-series Mac, Rosetta 2 translates its instructions into Apple Silicon instructions, mostly ahead of time rather than line by line while the app runs, which is why translated apps feel close to native speed for most everyday tasks. It is translation, not emulation, and that distinction is why it has held up as well as it has for five years.

It does have real limits. Rosetta 2 cannot load kernel extensions, cannot run a different-architecture virtual machine inside itself (an Intel Windows or Linux VM will not run under Rosetta), and does not support AVX-512 vector instructions. Most ordinary desktop software never runs into those limits. Specialized audio, scientific, and virtualization tools sometimes do.

The Real Timeline

This is the part that actually changed recently. At WWDC 2025, Apple confirmed for the first time exactly how long Rosetta 2 would stick around as a general-purpose tool, rather than leaving developers to guess. Here is where things stand as of this writing.

macOS version	Release	Runs on Intel Macs	Rosetta 2 for Intel apps
Tahoe (26)	Shipped Sept 2025; current is 26.6	Yes, last version that does	Full. Warning dialog added in 26.4 (Feb 2026)
27, "Golden Gate"	Expected Sept 2026 (public beta underway)	No, Apple Silicon only	Full. Last version with general-purpose Rosetta 2
28 (name unannounced)	Expected fall 2027	No	Scaled back: legacy game titles and Intel-in-Linux-VM only

Two things are easy to conflate here, so it is worth separating them. macOS 27 drops Intel Mac hardware support, meaning it will not install on any Intel Mac at all. It does not drop Rosetta 2 itself, which keeps working at full strength on Apple Silicon Macs running macOS 27. The cutoff for Rosetta 2 as a general tool for translating Intel apps is macOS 28, a full release later.

If you are on an Intel Mac today, your machine keeps working exactly as it does now. It will simply never be offered macOS 27, since that release requires Apple Silicon. Apple has historically kept patching the previous two major macOS versions with security updates after a new one ships, so Tahoe should keep receiving critical fixes for a while past macOS 27's release, just without new features, and eventually without any updates at all.

How to Find Every Intel-Only App on Your Mac

You do not need a third-party tool for this. macOS already tracks the architecture of every installed app, and there is a built-in way to see all of them sorted in one list.

Open System Information

Free · 30 sec

Click the Apple menu, choose About This Mac, then click More Info and System Report. On older macOS versions System Report is offered directly in the About This Mac window.

Go to Software, Applications

Free · 30 sec

In the sidebar, expand Software and click Applications. This lists every app macOS has scanned, no matter where it is installed.

Sort by the Kind column

Free · 1 min

Click the Kind column header. Apps sort into Apple Silicon, Universal (contains both architectures), Intel, and occasionally iOS or Other for apps macOS cannot classify.

Review everything marked Intel

Manual · varies

Every app in that group needs Rosetta 2 to run on your Mac today, and will stop opening once general Rosetta 2 support ends. Apple Silicon and Universal apps need nothing extra.

Double-check a specific app if you want

Manual · 10 sec each

Select the app in Finder and press Command-I. The Kind field reads Application (Intel) if it needs Rosetta. To check while an app is actually running, open Activity Monitor, click the CPU tab, and look at its Kind column the same way.

Rosetta 2 usually installs itself automatically the first time you launch an Intel-only app, with a one-time system prompt. To install it ahead of time from Terminal instead:

softwareupdate --install-rosetta --agree-to-license

Leaving off the --agree-to-license flag runs the same install interactively and asks you to type A to accept the license first.

What Is Still Intel-Only in 2026

After five years of Apple Silicon, most mainstream software has gone native. What is left tends to fall into a few honest categories:

Abandoned indie and hobby apps. Small utilities whose developer moved on or stopped updating years ago. We covered a real example of this in our comparison of Recento vs Recent Menu, a once-popular recent-files utility whose last build shipped in the OS X Yosemite era and never went native.
Legacy enterprise and internal tools. Line-of-business software built once, deployed widely, and never prioritized for a rebuild.
Older pro audio and video plugins. Some DAW and NLE plugin catalogs still carry Intel-only entries from smaller developers.
Printer and scanner drivers. Hardware vendors have historically been slow to ship Apple Silicon drivers for older device models.
Old games. The one category Apple has explicitly said Rosetta 2 will keep serving even after macOS 28.

A community-tracked database referenced by several Mac publications in 2026 puts the number of Intel-only apps with no confirmed native update path at well over 18,000, which sounds alarming until you realize most of that long tail is niche, unmaintained, or already replaceable.

Should You Actually Worry?

Use a simple test. For each Intel-only app you actually use, ask whether the developer is still active.

If the app has shipped an update in the last year, or the developer has a changelog, a support page, or a public roadmap that is not dead, a native or Universal build is probably already planned or in progress. That is not something to worry about yet, just something to keep an eye on.

If the app has not been touched in three or more years, has no changelog activity, and the developer is unreachable or the company no longer exists, treat it as permanently Intel-only. Waiting will not fix that one. Plan its replacement now, while you have a year and a half of runway, rather than the week macOS 28 ships.

Your Options When an App Will Never Go Native

Option	Effort	How long it lasts
Switch to a native or Universal alternative	Low to medium, one migration	Indefinite, no expiration attached
Keep using it under Rosetta 2 today	None	Until macOS 28 (fall 2027), then it stops opening
Run it inside a macOS virtual machine	Medium, needs VM software (UTM, Parallels, VMware Fusion)	As long as the guest macOS version inside the VM still includes Rosetta 2
Keep an old Intel Mac around for it	Low if you already own one	Until the hardware fails or security updates for its last macOS version stop

The virtual machine option is worth knowing about even if it sounds excessive: you can run an older Apple Silicon macOS release, one that still has full Rosetta 2, as a guest VM on top of a newer host. The guest keeps working as long as it boots, independent of what the host macOS version has moved on to. It is more setup than most people want for a single utility, but it is a real, legitimate escape hatch for something you truly cannot replace.

Picking New Software So This Does Not Happen Again

The cheapest fix here is prevention. Apple Silicon Macs have shipped since November 2020, so any app you install for the first time today should already be a Universal binary or Apple Silicon native, full stop. If a product page or App Store listing does not mention Apple Silicon or Universal support, that is worth a direct question to the developer before you pay for it, or a quick check of the Kind field after you install it.

It is a small thing to verify, and it is easy to check on our own products as an example: Files Magic AI runs on macOS 12 Monterey and later on both Apple Silicon and Intel, Recento and Apple Notes Exporter Pro both ship as Universal binaries on macOS 11 Big Sur and later. None of that is unusual for software built in the last few years, it is simply the baseline worth confirming before you commit to something new.

Frequently Asked Questions

Is Rosetta 2 still supported in 2026?

Yes. As of macOS Tahoe 26.6, Rosetta 2 works exactly as it always has, and Apple has confirmed it will remain fully available through macOS 27 (Golden Gate), expected in September 2026. Starting with macOS 26.4, Tahoe began showing a warning when you open an Intel-only app, but the app still runs. The warning is advance notice, not a current restriction.

When will Rosetta 2 actually stop working?

General-purpose Rosetta 2 support ends with macOS 28, expected in fall 2027. From that release onward, Apple has said it will keep only a narrow subset of Rosetta functionality for older, unmaintained game titles and for Intel binaries inside Linux virtual machines. An ordinary Intel-only productivity app, plugin, or utility will not open once you are on macOS 28.

How do I know if an app on my Mac needs Rosetta 2?

Open About This Mac, click More Info, then System Report, then Software and Applications. Click the Kind column header to sort every installed app by Apple Silicon, Universal, or Intel. Anything marked Intel needs Rosetta 2. For a single app, select it in Finder and press Command-I; the Kind field reads "Application (Intel)" if it needs translation.

Can I install Rosetta 2 manually instead of waiting for the prompt?

Yes. Open Terminal and run softwareupdate --install-rosetta. You will be asked to agree to the license by typing A. To skip that prompt, run softwareupdate --install-rosetta --agree-to-license instead. In practice you rarely need to do this yourself, since macOS installs Rosetta 2 automatically the first time you launch an Intel-only app and offers the same prompt.

Will my Intel Mac stop working after macOS 27 comes out?

Your Mac keeps working exactly as it does now. macOS Tahoe (26) is the last version that installs on Intel Macs, since macOS 27 is Apple Silicon only, so an Intel Mac simply will not be offered that update. Based on Apple's usual pattern of patching the previous two major versions, Tahoe should keep receiving security updates for a couple of years after macOS 27 ships, but it will not gain new features and will eventually stop receiving any updates at all.

What actually happens to an Intel-only app after macOS 28?

It will not launch. Without Rosetta 2 to translate its Intel instructions, macOS on Apple Silicon has no way to run the binary at all, and you will get an error rather than a warning. The only exceptions Apple has named are certain legacy, unmaintained games and Intel code running inside a Linux virtual machine, neither of which covers ordinary desktop software.

Is an app running under Rosetta 2 noticeably slower?

Usually only a little. Rosetta 2 translates Intel code into Apple Silicon instructions ahead of time rather than interpreting it line by line, which is why it performs close to native speed for most everyday apps. The gap shows up more in demanding workloads: apps that need kernel extensions or AVX-512 vector instructions will not run under Rosetta 2 at all, and apps that try to run a different-architecture virtual machine inside themselves are also unsupported.

Should I avoid buying new Mac software that is Intel-only?

Yes. Any app you are installing fresh today should already be a Universal binary or Apple Silicon native, since Apple Silicon Macs have shipped since late 2020. If a product page or App Store listing does not mention Apple Silicon or Universal support, check the Kind field after installing it, or ask the developer directly before you pay for something that may stop working when macOS 28 arrives.
