Intel Apps Won’t Open in macOS 28: How to Find Every Intel-Only App, Plug-in and Driver

If you’ve opened an older app on macOS 27 and got a warning about Rosetta, it isn’t a formality. Apple has confirmed that Rosetta 2 stays available throughout macOS 27, and that from macOS 28 onward, Intel-based apps won’t open. The one exception is a subset of Rosetta for older, unmaintained games that depend on Intel frameworks.

macOS 28 is expected next fall, which gives you roughly a year. That sounds like plenty, right up until you discover the Intel-only printer driver, the audio plug-in your whole project depends on, or a utility whose developer vanished in 2021.

This guide shows how to find every Intel-only component on your Mac, not just the apps you can see in Finder, and what to do about each one.

What’s changing, exactly

Apple began warning about this in macOS 26.4, with alerts when you launch Intel apps. Golden Gate makes those warnings more prominent.

Why this is happening now

The Intel-to-Apple-silicon move started in 2020, and keeping an entire translation layer alive for years costs Apple engineering effort. ARM is also where the wider industry is heading: even NVIDIA’s new RTX Spark is an ARM chip, although why RTX Spark won’t appear in a Mac is a separate question about Apple’s control of its own silicon. For you, the practical upshot is simple: x86-only software has an expiry date.

Step 1: Check Apple’s built-in list

Golden Gate includes a list of Intel apps you’ve used recently.

Go to System Settings > General > About, find Intel-based Apps and click Details. You’ll see the Intel apps opened on this Mac over the past year. Hover over one to reveal it in Finder or move it to the Trash.

It’s a good start with two blind spots: it only lists apps you’ve actually opened recently, and it doesn’t show components that load inside other apps, such as plug-ins and drivers.

Step 2: Scan every app, not just recent ones

System Information can show every installed app with its architecture. Hold Option, open the Apple menu and choose System Information. Then go to Software > Applications and sort by the Kind column. Apps marked Intel are Intel-only.

For a faster list you can copy, run this in Terminal. It checks the main executable of every app in both Applications folders and prints the Intel-only ones:

find /Applications ~/Applications -maxdepth 3 -name "*.app" -prune 2>/dev/null |
while IFS= read -r app; do
exe=$(defaults read "$app/Contents/Info" CFBundleExecutable 2>/dev/null) || continue
archs=$(lipo -archs "$app/Contents/MacOS/$exe" 2>/dev/null) || continue
[[ "$archs" == "x86_64" ]] && echo "Intel-only: $app"
done

lipo -archs prints the CPU architectures inside a binary. x86_64 arm64 means Universal, arm64 means native, and only x86_64 on its own is a problem.

Step 3: Check plug-ins, the most common surprise

Plug-ins load inside a host app, so they never show up in an app list. On Golden Gate there may not even be a Rosetta prompt: audio producers have reported Intel-only plug-ins silently vanishing from Logic Pro after upgrading.

Scan audio plug-ins (Audio Units, VST, VST3, AAX):

find /Library/Audio/Plug-Ins ~/Library/Audio/Plug-Ins -path "*/Contents/MacOS/*" -type f 2>/dev/null |
while IFS= read -r bin; do
[[ "$(lipo -archs "$bin" 2>/dev/null)" == "x86_64" ]] && echo "Intel-only: $bin"
done

The same approach works for other plug-in folders. Common locations include /Library/Internet Plug-Ins, subfolders of ~/Library/Application Support/ for creative apps, and /Library/QuickLook.

Step 4: Check printer and scanner drivers

Printer and scanner drivers are reported to be the single biggest category of Intel holdouts, and they’re easy to forget because you install them once and never think about them again.

List your installed printers:

lpstat -v

Scan vendor driver files for Intel-only binaries:

find /Library/Printers /Library/Image\ Capture -type f 2>/dev/null |
while IFS= read -r f; do
[[ "$(lipo -archs "$f" 2>/dev/null)" == "x86_64" ]] && echo "Intel-only: $f"
done

Files that aren’t executables are skipped automatically, because lipo can’t read them.

Step 5: Decide what to do with each one

Put everything you found into one list. For each item, note what it does, its version, whether the developer is still active and what you plan to do. Then sort the list into four groups.

1. An update exists. Check the developer’s site or the App Store. Many apps went Universal years ago, and you may simply be running an old copy. For paid apps, find out whether the Apple silicon version costs an upgrade fee and budget for it now.

2. A replacement exists. For abandoned apps, find an actively maintained native alternative. Do it in a quiet month, not the week macOS 28 ships, and test the replacement with your real files.

3. The system can replace a driver. Many network printers support driverless printing through AirPrint or IPP Everywhere. Remove the printer in System Settings > Printers & Scanners, add it again and choose the AirPrint or Secure AirPrint option if it’s offered. If basic printing works, you may not need the vendor driver at all. You might lose some advanced features, such as certain finishing options, so test the ones you actually use.

4. Nothing replaces it. This is the hard group: specialized hardware drivers, industry software, old plug-ins tied to archived projects. Your options:

Keeping a dedicated old-software Mac usually means buying a newer one for everything else. If that’s where you’re heading, read NVIDIA RTX Spark in a MacBook or iMac first, so you know what’s actually coming to the Mac lineup before you spend money.

Bonus: check your Terminal and developer tools

Developers and command-line users have one more place to look. A Terminal or shell that runs under Rosetta, or a Homebrew installed for Intel, drags Intel binaries into everything it builds and installs.

arch
brew --prefix

arch should print arm64. If it prints i386, your Terminal is running under Rosetta, so check its Get Info settings. For Homebrew, /opt/homebrew is the native Apple silicon location, while /usr/local usually means an Intel installation that needs migrating before Rosetta goes away.

What about games?

Apple says a subset of Rosetta will remain in macOS 28 for older, unmaintained games that rely on Intel-based frameworks. Which titles qualify, and how it will work in practice, hasn’t been detailed yet. If gaming is your only reason for relying on Rosetta, you’re in a better spot than users of Intel-only productivity software, but don’t assume every game will keep working.

A timeline that works

The end of Rosetta has been coming since 2020, and for most people it will pass without incident. The Macs that get caught out are the ones where nobody checked the plug-ins folder. It takes ten minutes to make sure yours isn’t one of them. If a hardware refresh ends up on your list, our guide to what could actually happen with RTX Spark and the Mac lineup helps you time it.
