Apple's six-year Intel-to-silicon bridge is entering its final stretch. With macOS 26.5 — the current shipping version of macOS, released May 11, 2026 — every Mac user who opens an Intel-only app now sees a system warning stating it will stop working in a future macOS release. That future is fall 2027, when macOS 28 is expected to cut off Rosetta 2 compatibility for virtually all Intel-based software. A community-tracked database of Intel-only Mac apps already counts more than 18,800 titles — ranging from legacy enterprise software to specialist audio plugins — that have not been compiled for Apple Silicon and have no confirmed path to a native update.
For the majority of Mac users, the warnings are noise: most popular consumer apps have long since shipped universal or Apple Silicon-native builds. The disruption will fall disproportionately on three groups — IT administrators managing enterprise fleets that still run proprietary or custom line-of-business software, creative professionals who depend on Intel-only audio plugins or design tools, and anyone who relies on unmaintained utilities whose developers have moved on.
Apple's official guidance is unambiguous: users and IT teams should replace Intel-only apps with Universal or Apple Silicon-native versions before macOS 28 arrives. The time to do that is now, not in 2027 when the door is already closed.
Rosetta 2 Was Always Temporary
Rosetta 2 is a translation layer Apple built into macOS to let Intel-compiled software run on its M-series processors without modification. When Apple introduced the first M1 Macs in November 2020, it made a deliberate choice to ease the transition by running Intel code silently and automatically in the background, rather than forcing an immediate cutover. The bet paid off — Rosetta 2's performance was close enough to native that many developers delayed rebuilding their apps, and many enterprise users barely noticed they were running translated software at all.
Apple's own statement, published at WWDC 2025, explains the timeline it committed to: "Rosetta was designed to make the transition to Apple silicon easier, and we plan to make it available for the next two major macOS releases — through macOS 27 — as a general-purpose tool for Intel apps to help developers complete the migration of their apps."
That window is now closing. macOS 26 Tahoe, released in September 2025, is the last macOS version to run on Intel-based Mac hardware. Starting with macOS 27 — expected in fall 2026 — the operating system will run only on Apple Silicon. And starting with macOS 28, expected in fall 2027, Rosetta 2 will largely stop working, with one narrow exception: Apple has said it will retain a limited subset of Rosetta functionality specifically for "older, unmaintained gaming titles that rely on Intel-based frameworks." Enterprise software, audio plugins, and business utilities are not covered by that exception.
The transition mirrors Apple's previous architectural shift almost exactly. When Apple moved from PowerPC to Intel in 2006, it introduced the original Rosetta translation layer — which it then dropped with Mac OS X Lion in July 2011, roughly five and a half years after the first Intel Mac shipped. History is following the same arc: the first M1 Macs arrived in November 2020, and Rosetta 2 is set to be largely retired by fall 2027 — seven years later, after developers have had longer runway than in any previous Apple transition.
Apps at Risk: Enterprise Tools, Creative Plugins, Legacy Utilities
The good news is that most mainstream consumer apps have already been updated. The bad news is that a significant tail of specialized and unmaintained software has not — and a meaningful share probably never will be.
The highest-risk categories are:
Legacy enterprise and business software. Older line-of-business applications, proprietary internal tools, and niche industry software are the most vulnerable. As Computerworld noted in its guidance to IT administrators, any remaining Intel apps a company depends on must be replaced to maintain business continuity and security; developers of those apps may lack the resources or commercial incentive to rebuild for Apple Silicon. MDM platforms such as Jamf Pro can identify affected software across a managed device fleet.
Audio production and creative plugins. Many audio plugins, older versions of design tools, and specialist scientific utilities were never rebuilt for Apple Silicon. Developers of those tools have often moved on, and no update is coming.
CAD and drafting applications. A number of computer-aided drafting and engineering tools still ship Intel-only builds. The discontinuation will directly affect users of these applications on Apple Silicon Macs.
Abandoned or unmaintained utilities. Any Intel-based app that has not already been rebuilt will not be rebuilt. If a developer has not acted in the five-plus years since the M1 launch, the window to act is near closing.
How to Check Which Mac Apps Will Break When Rosetta 2 Ends
Users do not need to wait for a warning dialog to appear. Three methods can identify Intel-dependent apps on any Mac today.
Via Activity Monitor. Open Activity Monitor from Applications > Utilities, select the CPU tab, and look at the "Kind" column. Any process listed as "Intel" is currently running through Rosetta 2 and will stop functioning on macOS 28.
Via Get Info. Right-click any app in Finder and choose Get Info. Check the "Kind" field. An app labeled "Application (Intel)" is Intel-only. Apps labeled "Universal" or "Application (Apple silicon)" are safe.
Via System Information. Open System Information (hold Option and click the Apple menu > System Information), select Applications in the left sidebar, and click the Kind column header to sort apps by architecture. All Intel-only apps will group together for easy review.
Via third-party tools. iMazing offers a free "Silicon" scanning tool that identifies Intel-dependent apps across an entire Applications folder and reports each app's architecture. A community database called RosettaCheck tracks more than 18,800 Intel-only apps and provides migration suggestions for each.
What To Do About Affected Apps
Apple's guidance is direct: for any app showing a Rosetta warning, replace it with a Universal or Apple Silicon version before macOS 28 arrives.
For App Store apps: check the App Store directly for updates. A Universal build replaces the Intel version automatically.
For apps downloaded outside the App Store: visit the developer's website and look for a version labeled "Universal" or "Apple silicon." If the developer's page makes no mention of Apple Silicon support, contact them and ask whether a native build is planned.
For apps with no update path: the time to find an alternative is now. An Intel-only app that has not been updated in the five years since M1 launched is unlikely to be updated before macOS 28 ships.
For IT administrators: Computerworld's guidance advises replacing all Intel-dependent software on managed fleets before the macOS 28 deadline. macOS 26 Tahoe is also the final OS upgrade available to Intel-based Macs themselves, so hardware refresh plans and software replacement should be treated as parallel workstreams. Jamf Pro and similar MDM tools can run fleet-wide architecture audits to identify affected software at scale.
One nuance worth noting: some apps that show a Rosetta warning are Universal apps whose internal helper tools or plugins contain Intel-only components. These apps will continue to run after macOS 28, but will lose functionality tied to those Intel components — so the warning is accurate even if the main app is not purely Intel.
The macOS 26.5 warnings are not an emergency — Intel apps continue to function normally today, and Rosetta 2 will remain fully operational through macOS 27 in fall 2026. But seven years after the M1 launch, the transition has a fixed endpoint. The apps on a user's Mac that have not yet been updated almost certainly never will be. Finding out which ones those are — and deciding now whether to replace them or accept the loss — is the only action that matters.
Frequently Asked Questions
What happens when Rosetta 2 support ends on macOS?
Starting with macOS 28, expected in fall 2027, nearly all Intel-only applications will stop running on Apple Silicon Macs. Rosetta 2 will be retained only for a narrow category of older, unmaintained gaming titles that rely on Intel-based frameworks. Enterprise software, audio plugins, business utilities, and all other Intel-only apps will simply fail to open unless developers have shipped a Universal or Apple Silicon-native version.
How do I check if my Mac apps are Intel or Apple Silicon?
Open Activity Monitor (Applications > Utilities), go to the CPU tab, and check the "Kind" column — any process labeled "Intel" runs through Rosetta 2 and will break on macOS 28. Alternatively, right-click any app in Finder, choose Get Info, and check the Kind field. Apps labeled "Application (Intel)" need to be replaced or updated; apps labeled "Universal" or "Application (Apple silicon)" are safe.
What Intel apps will stop working in macOS 28?
A community database called RosettaCheck currently tracks more than 18,800 Intel-only Mac apps that have not been compiled for Apple Silicon, including scanner utilities, audio plugins, older CAD tools, legacy enterprise software, and specialist scientific applications. Apps that have shipped Universal or Apple Silicon-native builds will continue working normally.
Will my Intel Mac still receive security updates after macOS 26?
macOS 26 Tahoe is the last macOS version that supports Intel-based Mac hardware; Intel Macs will not receive macOS 27. Apple typically provides security patches for older macOS versions for a few years after they fall out of the update cycle, so Intel Macs will likely receive some security fixes for a limited time after macOS 27 arrives — but they will not gain new features and will eventually stop receiving any updates.
