You cannot find x86_64 versions of applications on your MacOS arm64 (M1) system because most modern software is distributed as universal binaries or native arm64 builds. Rosetta 2 handles the translation automatically, so you typically do not need to locate separate x86_64 installers. If an app fails to run, reinstalling it or checking for updates usually resolves the compatibility issue without manual architecture selection.
Understanding Universal Binaries and Architecture
Apple Silicon Macs use the arm64 architecture, while older Intel-based Macs used x86_64. When developers release applications today, they often create universal binaries that contain code for both architectures within a single file. This means that when you download an application from the App Store or a developer website, it likely already supports both M1/M2/M3 chips and Intel processors. You do not need to choose between different versions; the operating system detects your hardware and runs the appropriate code path automatically.
If an application is listed in your downloads but appears missing from the Applications folder, it may be because the installer placed it in a different location, or the file was downloaded but never executed. Check your Downloads folder for a .dmg file. Double-clicking this disk image will mount it and display the application icon. Dragging this icon into the Applications folder completes the installation process.
Verifying Rosetta 2 Installation
Rosetta 2 is the translation layer that allows x86_64 applications to run on arm64 hardware. It is installed by default on Apple Silicon Macs running recent versions of macOS. However, if you encounter errors stating that Rosetta 2 is required, you can ensure it is properly installed through the Terminal. Open the Terminal application and execute the following command:
softwareupdate --install-rosetta
This command prompts for your administrator password and installs the necessary components. If Rosetta 2 is already present, the system will confirm that no update is needed. Avoid using any third-party tools or scripts that claim to manage Rosetta 2 manually, as these can interfere with system integrity. The official Apple method ensures that all system libraries are correctly linked.
Troubleshooting Missing or Non-Running Apps
When an application does not appear in Spotlight or the Launchpad, several factors could be at play. First, verify that the app is not hidden. Right-click the Finder icon in the Dock and select "Show Options." Ensure that the "Always Show Hidden Items" setting is turned off, as this might affect visibility in certain views. More commonly, the application may have crashed due to architecture mismatch.
Check the Console app for error logs related to the specific application. Look for messages indicating "bad CPU type in executable," which suggests the binary is incompatible with your current environment. In such cases, updating the application to the latest version provided by the developer is the most effective solution. Developers frequently release patches to address compatibility issues with newer macOS versions.
If you recently upgraded your macOS, some older applications may require a fresh installation to register correctly with the new system framework. Uninstall the application completely by moving it to the Trash, then restart your Mac. Re-download the installer from the official source and install it again. This process clears any corrupted cache files that might prevent the app from launching.
Managing Application Permissions and Security
macOS includes strict security measures that can block applications from unknown developers. When you attempt to open an x86_64 app via Rosetta 2, you might see a warning that the app cannot be opened because it is from an unidentified developer. Navigate to System Settings, then Privacy & Security. Scroll down to find the Security section. If the blocked app is listed, click "Open Anyway." You will be prompted to confirm this action.
This step is crucial for maintaining system security while allowing legitimate software to function. Never disable Gatekeeper entirely, as this exposes your Mac to malicious software. Instead, only grant permissions to applications you trust and have obtained from reputable sources. For enterprise environments, consider using managed configuration profiles to whitelist specific apps.

Common Misconceptions About Architecture Selection
Many users believe they must manually select the x86_64 version of an app to ensure stability. This is rarely true for well-maintained software. Universal binaries are optimized to run natively on arm64 when available, providing better performance and battery life. Forcing an app to run in emulation mode can lead to slower performance and higher resource usage.
If an application specifically requires x86_64 execution, it is usually indicated in the app's metadata or documentation. Most users do not need to intervene in this process. The operating system handles the routing transparently. Attempting to force architecture selection through unsupported commands can break system functionality and void warranties.
Regarding Java development on these systems, ensuring you have the correct arm64 version is vital. See our article on

Frequently Asked Questions
Why does my app crash immediately after opening?
The crash is likely due to an incompatibility between the app binary and your macOS version. Check for updates from the developer, as they may have released a fix for Apple Silicon compatibility. If no update exists, contact the support team directly for assistance.
Can I uninstall Rosetta 2 to free up space?
It is not recommended to remove Rosetta 2 unless you exclusively use native arm64 applications. Removing it will prevent any x86_64 apps from launching. You can reinstall it later using the standard softwareupdate command if needed.
How do I check if an app is universal?
Right-click the application in Finder and select "Get Info." Look for the "Kind" field, which may indicate "Universal Binary" or "Application." Alternatively, use the Terminal command
file on the app bundle to view its architecture details.
What should I do if Spotlight doesn't find my app?
Rebuild the Spotlight index by going to System Settings, then General, and selecting Spotlight. Click the Privacy tab and add your hard drive, then remove it. This forces macOS to re-index all files and folders. Restart your Mac after completing these steps.
Is it safe to use third-party tools to manage architectures?
No, using third-party tools to modify system architectures can compromise security and stability. Stick to official Apple utilities and commands. These tools often bypass critical safety checks and may introduce malware or system instability.
