Apple Silicon Chips

If you bought your computer after late 2020, chances are it has a new Apple silicon chip instead of an Intel processor: let's find out.

Open a new terminal window from Applications > Utilities or search for it with Spotlight:

Copy-paste the following command in the terminal and hit Enter to execute.

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/lewagon/setup/master/utils/macos_list_processor_type.sh)"

☝️ The result of the command should indicate whether your computer uses Apple Silicon.

If your computer uses Apple Silicon, expand the paragraph below and go through it. Otherwise ignore it.

Uninstall Homebrew

We need to uninstall Homebrew in case a native version was installed.

Execute the following command in the terminal:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)"

If brew was not installed you will get the message brew: command not found!

Configure Terminal for Rosetta

Open the Finder app (or search for it with Spotlight).

Go to Applications > Utilities.

Duplicate the terminal app (select it, then Cmd + C, Cmd + V), and rename a copy as Terminal Rosetta.

Press Cmd + I on the Terminal Rosetta app, then check the box "Open using Rosetta".

⚠️ From now on during the bootcamp, whenever you are asked to open a Terminal, you will use the Terminal Rosetta app.
