How to Ensure Rosetta 2 is Installed on macOS

Learn how to ensure Rosetta 2 is installed on your Apple Silicon Mac to run Intel-based applications. Follow these simple steps using Terminal to enable compatibility with a wide range of software on your macOS.

If you are using a Mac with Apple Silicon (M1 or later), you may encounter software or applications that are not natively designed for the ARM-based architecture. To run these Intel-based apps on your Mac, you need Rosetta 2, a translation tool that enables compatibility. This guide will walk you through how to ensure that Rosetta 2 is installed on your macOS.

Using Terminal to Install Rosetta 2

  1. Open Terminal: To get started, you’ll need to open the Terminal app on your Mac. You can find it in the Applications > Utilities folder, or you can use Spotlight to search for it.

  2. Run the Installation Command: In the Terminal window, type the following command and press Enter:

softwareupdate --install-rosetta

This command will trigger the installation of Rosetta 2 on your system. If it’s already installed, it will confirm that it’s up to date.

  1. Agree to the Terms: After running the command, you may be prompted to agree to the terms of the software license agreement. The Terminal output should resemble the following:
I have read and agree to the terms of the software license agreement. A list of Apple SLAs may be found here:
Type A and press return to agree: A

To accept the terms, simply type ‘A’ (for ‘Agree’) and then press Enter.

  1. Installation Confirmation: Once you’ve agreed to the terms, Rosetta 2 will be downloaded and installed on your Mac. You should see a confirmation message like this:
Install of Rosetta 2 finished successfully

This indicates that Rosetta 2 is now installed and ready to assist you in running Intel-based applications on your Apple Silicon Mac.

That’s it! You’ve successfully ensured that Rosetta 2 is installed on your macOS, making your Mac more versatile and compatible with a wide range of software.
