One of the reasons I took the plunge and bought an M1-based Mac is to test out its performance and suitability as a developer<\/i>. An essential developer application on the Mac is Homebrew<\/a>, the “missing package manager for macOS.” Although you cannot install Homebrew today to manage ARM-compiled packages<\/a>, you can install Homebrew in the Rosetta<\/i> environment and leverage the x86 packages.<\/p>\n

I can’t take credit for coming up with the idea, that would go to OSX Daily<\/a>, but I have a few improvements to share. I’m going to use iTerm2<\/a>, and so should you.<\/p>\n

Right click on your iTerm application icon and select Duplicate<\/strong>. Rename iTerm copy<\/strong> to something like iTerm x86<\/strong> or iTerm Rosetta<\/strong>.<\/p>\n

\"\"<\/a><\/p>\n

Now, right click on your new iTerm icon and click on Get Info<\/strong> and then check Open using Rosetta<\/strong>.<\/p>\n

\"\"<\/a><\/p>\n

Open your iTerm Rosetta<\/strong> application and install Homebrew! Once installed you should be able to use brew install<\/code> in the iTerm Rosetta<\/strong> application and use those installed packages seamlessly between the two environments. You won’t<\/em>, however, be able to use brew install<\/code> in your arm64 iTerm<\/strong> application (you’ll get Error: Cannot install in Homebrew on ARM processor in Intel default prefix<\/code>).<\/p>\n

Keeping Track<\/h2>\n

If you’re working in both x86 and ARM environments on your M1 Mac it is easy to lose track which iTerm you are in. We can use a little zsh<\/code>-foo to help us out. Add the following snippet to the end of your ~\/.zshrc<\/code>:<\/p>\n

\n_ARCH=$(arch)\nPROMPT=\"$_ARCH $PROMPT\"\n# Requires iterm2\nif [[ \"$_ARCH\" == \"i386\" ]]; then\n  echo -ne \"\\033]1337;SetColors=bg=0071C5\\007\"\nfi\n<\/pre>\n
This little snippet takes advantage of iTerm2’s custom escape codes<\/a> by setting the background to Intel blue<\/a> if the arch<\/code><\/a> command returns i386<\/code> (which it does if running in Rosetta).<\/p>\n
\"\"<\/a><\/p>\n
We can do one better, however, by changing our iTerm Rosetta icon.  Create your own icon, or, right-click the image below and select Copy Image<\/strong>.  Then right-click your iTerm Rosetta<\/strong> application and select Get Info<\/strong>.  In the upper-left click on the icon until you see a highlight around it and then paste the new icon image (Command-V).<\/p>\n
\"\"<\/a><\/p>\n
Launch your iTerm Rosetta<\/strong> application and it’s much easier to distinguish between it and your “native” version.<\/p>\n
