Rosetta sunset on macOS Golden Gate: which Mac apps are about to die

macOS 27 Golden Gate is not only a feature update. For a lot of home Mac users it is the last comfortable year for old Intel-only apps on Apple silicon.

Apple’s own support page is blunt: Rosetta stays available through macOS 27. Starting with macOS 28, Rosetta works only for certain older, unmaintained games that rely on Intel-based frameworks (Using Intel-based apps on a Mac with Apple silicon). Independent coverage from Ars Technica matches that policy: Golden Gate is the last macOS with broad Rosetta support for Intel apps, with a game carve-out afterward.

This is not “your Mac dies tomorrow.” It is a countdown. If you already upgraded (or you are about to), use Golden Gate as the year you inventory leftovers. For the install checklist itself, see our Golden Gate update day guide.

What Rosetta actually did (plain English)

When Apple moved Macs from Intel chips to Apple silicon, millions of apps were still compiled for Intel. Rosetta is the translator that lets those Intel-built apps run on M-series Macs without the developer rewriting them first.

You usually never open a Rosetta app. You launch something old, macOS may ask to install Rosetta once, then the app mostly just works. That convenience is why abandoned utilities and ancient plugins still linger on desks that otherwise feel modern.

“Dying” in this context means: after you move to macOS 28, those Intel-only apps (and many Intel-only plug-ins) stop launching for normal use. The files may still sit in Applications. They will not be a usable program anymore, except for the narrow game exception Apple documents.

Apple’s stated policy vs speculation

Stick to what Apple publishes:

Claim	Status
Rosetta available on Apple silicon through macOS 27	Apple Support
From macOS 28, Rosetta only for certain older unmaintained games	Apple Support
Golden Gate is Apple silicon only (no Intel Mac upgrade path)	Apple macOS page / release coverage
Exact calendar date for macOS 28	Not stated here. Do not invent one.
Which specific commercial apps will never get a native rebuild	Vendor-by-vendor. Apple will not publish your personal risk list.

Developer release notes during the Golden Gate cycle also describe inventory UI for Intel-based apps that will be incompatible with macOS 28, and warn that Intel-based plug-ins and loaders may not appear in Settings or notifications. Treat Apple’s Finder Kind labels and the System Settings list as helpful, not complete.

If a blog says “Rosetta is already gone in Golden Gate,” that conflicts with Apple’s September 14, 2026 support language. Prefer the support article.

How to check which apps are still Intel-only

Do this while you are still on macOS 27 (or earlier with Rosetta).

Finder Get Info (one app at a time)

Select the app in Finder (usually in Applications).
Choose File → Get Info (or press Command-I).
Read Kind:
- Application (Intel): needs a Universal or Apple silicon update, or a replacement.
- Application (Universal): fine for now. Some Universal apps still offer “Open using Rosetta” so old Intel-only plug-ins can load. That checkbox is a temporary bridge, not a forever plan.
- Application (Apple silicon): native. No Rosetta needed.

System Settings inventory (Golden Gate)

On macOS 27 or later, Apple documents:

System Settings → General → About
Click Details next to Intel-based Apps
Review the list of recently used or commonly installed Intel apps

Use that list as your starting backlog. Then manually check creative plug-ins, audio units, printer helpers, and odd Utilities folders that never show up in “recent apps.”

What is most at risk for a normal Mac user

You do not need a developer conference to spot the danger zones:

Abandoned niche utilities. Disk cleaners from 2019, ancient menu-bar weather apps, one-off converters whose website is a parked domain.
Old Creative Suite era plug-ins. Photoshop, Lightroom, Final Cut, Logic, and DAW hosts may themselves be Universal while a beloved filter, LUTs pack, or VST is still Intel-only. The host app survives. The plug-in vanishes.
Browser helpers and old kernel-adjacent junk. Anything that required weird “Open using Rosetta” rituals is waving a red flag.
Industry vertical tools with slow vendors. Niche genealogy, scanning, label-printing, or instrument software often ships years behind Apple silicon. Check the vendor site now, not the week macOS 28 lands.
Games with a possible carve-out. Apple says certain older unmaintained games keep Rosetta-style support in macOS 28. That is not a promise for every Steam leftover or every DRM wrapper. Verify per title when Apple and the storefront publish details.

What is usually fine: App Store apps that still receive updates, modern browsers, first-party Apple apps, and anything whose Get Info sheet already says Universal or Apple silicon.

What to do before and after upgrading

Before you jump to Golden Gate (or right after, if you already did)

Time Machine (or another real backup) before major OS changes. Syncing Documents to iCloud is not the same thing.
Run the Intel-based Apps inventory and screenshot or export the names you care about.
Update from the App Store or vendor sites while Rosetta still runs the old build. Sometimes the updater itself needed Rosetta once.
Contact or check developers for Universal / Apple silicon builds. If the answer is silence, start shopping replacements while the old app still opens.
Export projects and presets out of at-risk plug-in workflows (photo catalogs, DAW sessions, custom brushes) into formats a modern tool can read.

After Golden Gate, before macOS 28

Live on Golden Gate and notice which launches still bounce through Rosetta.
Replace Intel-only tools one by one. Do not wait for a forced cutover weekend.
If a Universal app only works because “Open using Rosetta” is checked for plug-ins, treat that as temporary scaffolding.
Keep one known-good backup of the last OS that still runs a must-have tool until its replacement is proven.

What “after upgrading” does not mean

Upgrading to Golden Gate does not instantly kill Intel apps. It is the last full Rosetta generation. The hard break Apple documents is macOS 28 for non-game Intel software.

Intel-only Macs are a separate story: they do not get Golden Gate at all. Stay on the last supported major for that hardware and keep applying security updates Apple still ships.

Do this / don’t do that

Inventory Intel-only apps and plug-ins during Golden Gate.
Prefer Universal or Apple silicon builds from vendors you trust.
Export data out of tools whose developers went quiet.
Read Apple’s Intel apps / Rosetta support article when a notification says support is ending.

Don’t

Assume every old game is safe forever because of the carve-out headline.
Trust a Settings list alone when you rely on plug-ins.
Wipe your Mac “to fix Rosetta” on a rumor.
Confuse “Intel Mac cannot install Golden Gate” with “Apple silicon Mac loses Rosetta today.”

Bottom line

Rosetta bought the Mac world six years of breathing room. On Apple silicon, macOS 27 Golden Gate is the last release where that translator still covers ordinary Intel apps. macOS 28 keeps a narrow path for certain old games and drops the rest, per Apple.

If you depend on anything whose Get Info sheet still says Application (Intel), Golden Gate is your warning year: update it, replace it, or plan to keep an older Mac/OS around for that one job. Everyone else can upgrade for Golden Gate features and still sleep fine, as long as the inventory happens before the next major version forces the issue.
