- Virtual Machine: Use a virtual machine like Parallels to run Intel apps on Apple Silicon Macs.
How do I install Rosetta 2?
Open Terminal:
To fix the “bad CPU type in executable” error on Mac, open Terminal, type softwareupdate –install-rosetta, and press Enter. This installs Rosetta 2, which helps run Intel apps on Apple Silicon Macs.
Run the Installation Command:
To fix the “bad CPU type in executable” error on your Mac, run the installation command for Rosetta 2 in Terminal. Open Terminal and type softwareupdate –install-rosetta to install it, then try running the app again.
Confirm Installation:
Confirm Installation means checking if a program or software has been correctly installed on your computer. You can confirm it by opening the app or using system settings to verify the installation was successful without errors.
Why do I see “bad CPU type in executable” on my Mac?
You see the “bad CPU type in executable” error on your Mac because the app you are trying to run is not compatible with your Mac’s processor. This often happens if the app was designed for Intel processors but you’re using a Mac with an Apple Silicon chip (like M1 or M2). You can fix it with Rosetta or by updating the app.
What is Rosetta 2, and how does it help?
Rosetta 2 is a tool on Apple Silicon Macs that helps run apps made for Intel-based Macs. It translates the code so these apps can work smoothly on newer Macs with Apple’s M1 or M2 chips. If you see the “bad CPU type in executable” error, Rosetta 2 can help fix it by allowing the app to run properly.
Can I run all Intel apps using Rosetta 2?
Most Intel apps work on Apple Silicon Macs with Rosetta 2, but some may not run perfectly. Rosetta 2 helps by translating Intel apps to work on new Macs, but it’s not always a perfect solution. If an app has issues, look for an updated version or an alternative that’s compatible with your Mac.

Does “bad CPU type in executable” occur with older macOS versions?
Yes, the “bad CPU type in executable” error can occur on older macOS versions, especially when trying to run apps that were made for Intel-based Macs on newer Apple Silicon Macs (M1, M2). This happens because the app isn’t compatible with the system’s processor. Updating the app or using Rosetta 2 can often fix the problem.
Can I update an app to fix this error?
Check for App Updates:
To fix the “bad CPU type in executable” error, check for app updates. Updating the app may provide a version compatible with your Mac’s processor, especially if it’s designed for Apple Silicon or Intel. Always use the latest version.
Use Universal Versions:
To avoid the “bad CPU type in executable” error on Mac, use Universal versions of apps. These versions are designed to work on both Intel and Apple Silicon Macs, ensuring compatibility and preventing the error from happening.
Contact Developer:
If you see the “bad CPU type in executable” error, contacting the app developer may help. They can provide a version that works with your Mac’s processor or guide you on how to run the app properly on your system.
Use Rosetta 2:
To fix the “bad CPU type in executable” error, use Rosetta 2 on your Mac. Rosetta 2 helps run Intel-based apps on newer Apple Silicon Macs (M1/M2). You can install it easily by following the steps in Terminal.
Consider Alternatives:
The “bad CPU type in executable” error happens when an app isn’t compatible with your Mac’s processor. This is common on newer Apple Silicon Macs trying to run apps made for Intel-based Macs. Using Rosetta or updating the app can help fix it.
What is a Universal app on Mac?
A Universal app on Mac is designed to work on both Intel and Apple Silicon processors. It means the app will run smoothly on any Mac, whether it has an Intel or M1/M2 chip. These apps are built to automatically adjust to the correct processor, ensuring compatibility and better performance on all Mac devices.
What if there’s no updated version of the app?
If there’s no updated version of the app, you can try using an alternative app that works with your Mac’s processor. Another option is to run the app on an older Intel-based Mac.
