Brew Command Not Found on Mac M1: Explained

If you have recently switched to a Mac M1, you may have encountered the frustrating issue of the “brew” command not being found. Homebrew, or simply Brew, is a popular package manager for macOS, allowing users to easily install and manage various software packages from the command line. However, due to the transition from Intel-based Macs to Apple Silicon M1 chips, some adjustments are required. In this article, we will explore the reasons behind this problem and provide you with possible solutions.

Why is Brew Command Not Found on Mac M1?

The primary reason why the “brew” command is not found on your Mac M1 is that Homebrew has not yet been fully optimized for the new Apple Silicon architecture. Homebrew relies on the x86_64 architecture and many packages in its repository are not natively compatible with the M1 chips. When you attempt to run the “brew” command on your M1 Mac, it will result in an error stating that “zsh: command not found: brew.”

Additionally, Apple Silicon Macs run on the ARM architecture, which is different from the x86_64 architecture used by Intel-based Macs. This architectural difference introduces compatibility issues, as most macOS software and package managers were traditionally designed for Intel Macs.

Solutions to Fix the “brew” Command Not Found Issue:

There are a few workarounds available to resolve this problem and quickly get Homebrew up and running on your Mac M1:

1. Update Rosetta 2:
Apple provides Rosetta 2, a built-in translation layer, to run Intel-based software on M1 Macs. To update Rosetta 2, open the Terminal and execute the following command:
“`

“`

2. Install Homebrew from Scratch:
As Homebrew is yet to be fully optimized for M1, you may need to reinstall it manually. Open the Terminal and run the following command:
“`
/bin/bash -c “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)”
“`

3. Add Homebrew to PATH:
Once Homebrew is installed, you need to add it to your system’s PATH environment variable. To do this, open the Terminal and edit the “.zshrc” file using a text editor:
“`
nano ~/.zshrc
“`
Then, add the following line to the file:
“`
export PATH=/opt/homebrew/bin:$PATH
“`
Save the changes and reload the updated “.zshrc” file by running:
“`
source ~/.zshrc
“`

4. Accept Homebrew Installation Directory Changes:
If you had Homebrew installed previously on an Intel-based Mac and migrated to a Mac M1, you may encounter permission issues due to changes in the default Homebrew installation directory. To resolve this, run the following command to accept the new install location:
“`
sudo mkdir /opt/homebrew
sudo chown -R $(whoami):admin /opt/homebrew
“`

Frequently Asked Questions (FAQs):

Q1: Is it safe to reinstall Homebrew?
A1: Yes, it is completely safe to reinstall Homebrew by following the provided command. It will not interfere with your existing applications or settings.
