What’s happening with Rosetta?
In 2020, Apple announced the transition from Intel processors to Apple silicon. Rosetta was designed to ease this transition by automatically translating Intel-based apps for use with Apple silicon. Rosetta will remain available throughout macOS 27, but starting with macOS 28, Rosetta functionality will only be available for certain older, unmaintained games that rely on Intel-based frameworks.
There’s plenty of time — but only if you know what’s on your system. Rosetta Check gives you the full picture in seconds.

macOS 26.4
Apple begins showing notifications when you launch Intel-based apps. The countdown starts.
macOS 27
Last macOS version with full Rosetta support. Your window to prepare.
macOS 28
Rosetta functionality limited to certain older games. Intel-based apps will no longer work.
Plugin and component scanning for Photoshop, Pro Tools, Logic Pro and more
Rosetta Check 2.0 goes beyond the apps in your Applications folder. It walks every audio, video, photo and 3D plugin folder on your Mac, plus the embedded helpers and XPC services hidden inside otherwise-native app bundles, and tells you exactly what will stop working when Rosetta 2 is removed.
Adobe Photoshop & Lightroom
Detects Intel-only Photoshop plugins (filters, panels, extensions) and Lightroom extensions that haven’t been ported. Surfaces vendor, version and install path so you know exactly which one needs updating.
Avid Pro Tools (AAX)
Scans every AAX plugin in your Pro Tools install for Intel-only builds. Old EQs, compressors, reverbs and instruments that never got an Apple silicon update are flagged with the same Intel/Universal/Apple silicon badges you already trust for apps.
Apple Logic Pro & GarageBand (AU)
Identifies Audio Units that lack Apple silicon support across every per-user and system Components folder. VST3 and CLAP plugins for Ableton, Studio One, Bitwig and Reaper are detected too.
Final Cut, Premiere, Blender, Cinema 4D, Maya
FxPlug effects for Final Cut Pro and Motion, Premiere extensions, plus 3D plugins for Blender, Cinema 4D and Maya. System extensions, Camera Extensions (virtual cameras), and login items are also scanned.
The Components tab
Every plugin grouped by host: AAX under Pro Tools, AU under Logic, VST3 under Ableton, FxPlug under Final Cut, Photoshop extensions under Photoshop. Toggle “Only Intel” to get a focused replacement list.
Component detail with AI alternatives
Tap any plugin to see architecture, vendor, version, install path, detection depth and a one-tap “Search Vendor” link. AI-generated alternatives from the RosettaCheck community help you find a native replacement.
Total Mac Readiness score — one percentage covering apps and plugins.
Live plugin monitoring — a Spotlight watcher fires within seconds when you drop a new VST3, AAX or AU into a plugins folder.
Deep bundle inspection — reads every embedded Mach-O inside Universal apps to surface Intel XPC services, helpers and login items hiding inside otherwise-native bundles.
Hidden in Apps view — jump from any app’s detail card straight to the embedded plugins, frameworks and helpers it ships.
Components CSV / JSON export — ships side by side with the apps export and is picked up automatically by MDM collection scripts.
Five new MDM keys — component monitoring, deep inspect, category filtering, grant prompting and readiness weights. All v1 keys still work.
Rosetta Check 2.0 is available now on the Mac App Store, and existing v1 users get the update automatically. Prefer the cutting edge? Join the TestFlight beta.

Frequently Asked Questions
Quick answers to common questions about Rosetta, Apple silicon, and this app.
Does Rosetta Check scan plugins for Photoshop, Pro Tools and Logic Pro?
Yes — Rosetta Check 2.0 scans every plugin folder on your Mac, including Adobe Photoshop and Lightroom extensions, AAX plugins for Avid Pro Tools, Audio Units (AU) for Apple Logic Pro and GarageBand, VST3 and CLAP plugins for Ableton, Studio One, Bitwig and Reaper, FxPlug effects for Final Cut Pro and Motion, Premiere extensions, plus 3D plugins for Blender, Cinema 4D and Maya. Each plugin is classified Intel, Universal or Apple silicon with the same colour-coded badges used for apps.
Why do plugins matter if my apps are already native?
When Rosetta 2 is removed in macOS 28, an Intel plugin loaded into a native host will simply fail to load. Pro Tools, Logic Pro, Photoshop and most creative apps already ship Apple silicon builds, but the third-party plugins inside them frequently haven’t been updated. Rosetta Check 2.0 surfaces those hidden Intel dependencies, plus the embedded XPC services and helper binaries shipped inside otherwise-native app bundles, so nothing breaks unexpectedly on upgrade day.
What plugin formats are supported?
Audio: Audio Unit (AU / AUv3), VST3, AAX, CLAP.
Video: FxPlug (Final Cut Pro, Motion), Premiere extensions.
Photo: Photoshop plugins and panels, Lightroom extensions.
3D: Blender add-ons, Cinema 4D plugins, Maya plugins.
System: System extensions, Camera Extensions (virtual cameras),
login items, embedded XPC services and helpers inside Universal app bundles.
What is Rosetta 2?
Rosetta is Apple’s translation technology that enables a Mac with Apple silicon to use apps built for a Mac with an Intel processor. Rosetta will remain available throughout macOS 27. Starting with macOS 28, Rosetta functionality will only be available for certain older, unmaintained games that rely on Intel-based frameworks. Learn more from Apple.
Why am I seeing a Rosetta notification on macOS?
Starting with macOS 26.4, Apple shows a notification each time you open an Intel-based app that uses Rosetta. It’s a heads-up that the app will need to be updated for Apple silicon before macOS 28. Rosetta Check lets you see all those apps in one place so you can plan ahead.
What do the architecture badges mean?
Apple silicon — runs natively on M-series chips.
Universal — includes both Intel and Apple silicon code; runs natively.
Intel — requires Rosetta to run on Apple silicon Macs.
Each app also gets an impact score that reflects how heavily it contributes to your overall
readiness percentage, so you can prioritise the apps that matter most.
What macOS version do I need?
Rosetta Check requires macOS 13 (Ventura) or later on any Mac with Apple silicon (M1, M2, M3, M4, or newer).
Does it work on Intel Macs?
Rosetta Check is designed for Macs with Apple silicon, where the transition away from Rosetta is relevant. It will scan and categorise apps on any supported Mac, but if you’re still on Intel hardware the Rosetta transition doesn’t directly affect you.
How much does it cost?
Rosetta Check is a one-time £6.99 purchase from the Mac App Store. No subscriptions, no in-app purchases, no ads. Buy once, use forever.
Privacy Policy
Personal data
Rosetta Check does not track you as a user. No names, email addresses, device identifiers, or IP-based profiling. No analytics SDKs, no advertising frameworks, no crash-reporting services. The app includes an optional community-sharing feature (disabled by default) that uploads anonymous app metadata to help improve recommendations — see “Community sharing” below for full details. No personal information is ever transmitted.
What the app accesses locally
The app uses the macOS Spotlight index
(NSMetadataQuery)
to discover installed applications and reads their
Info.plist
metadata to determine architecture, version, and bundle identifier. This is read-only access
within the standard app sandbox. No files are modified and no special permissions are required.
Network requests
Rosetta Check makes the following network requests:
-
Apple iTunes Search API
(
itunes.apple.com) — used to check whether a native Apple Silicon version of an app is available on the Mac App Store. Only the app’s bundle ID is sent; no user data is included. -
Rosetta Check community API
(
rosettacheck.com) — used to fetch AI-generated descriptions, replacement recommendations, and community suggestions for detected Intel-based apps. See “Community sharing” below for details on the optional upload feature.
No other network requests are made. There is no analytics, telemetry, or advertising traffic.
Community sharing (opt-in)
The app includes an optional feature to share your scan results with the Rosetta Check community database. This is disabled by default and must be explicitly enabled in Settings. When enabled, it sends only anonymous application metadata:
- App name, bundle ID, version, and architecture
- Disk size and category (from the app’s metadata)
- macOS version and chip family (e.g. “M2”)
A randomly generated anonymous identifier is used to deduplicate uploads — it is not derived from any hardware or personal information. No personal information, file paths, usernames, or anything that could identify you is ever transmitted. This data powers the community insights and AI recommendations that benefit all users.
Third-party services
Beyond the Apple iTunes Search API (operated by Apple Inc.) and the Rosetta Check community API (operated by us), the app does not integrate with any third-party SDKs, analytics services, advertising frameworks, or tracking tools.
Data deletion
All scan data is stored locally on your Mac. Uninstalling the app removes all locally stored data. If you opted in to community sharing, the anonymous app metadata previously submitted is aggregated and cannot be traced back to you. To request removal, contact us.
