Brew Operation Not Permitted: Troubleshooting Installation Errors on Mac

Homebrew is a popular package manager for macOS that allows you to install various packages and tools easily. However, some users might encounter errors during installation, such as the "brew operation not permitted" issue. This article will focus on this error and help you troubleshoot and resolve installation errors on your Mac.

Understanding the Error

When installing packages using Homebrew, the error message you receive may look similar to the following:

/usr/bin/env tar --extract --no-overwrite-dir -C /usr/local/Cellar/mysql-client/8.4.0 --verbose

Error: Permission denied @ apply2files - /usr/local/Cellar/mysql-client/8.4.0/bin/mysqldump

Resolving the Permission Issue

Launch the Terminal and enter the following command:

sudo chown -R $(whoami) /usr/local

Enter your Mac username and password when prompted.

The above command will adjust the ownership of the /usr/local directory, allowing you to install packages without encountering permission denied errors. Now, you should be able to install packages through Homebrew without any issues.

Ensure Homebrew is up-to-date:
