Migrate macOS apps with Homebrew ​

Export and import macOS applications using Homebrew and Brewfile.

Homebrew, also known as Brew, is a great way to install and manage software on macOS. Managing Brewfile in a repository allows you to easily export and import your installed applications.

Here is how to migrate your macOS applications from one Mac to another using Homebrew and a Brewfile.

Step 1: Export Brewfile from existing Mac ​

On your current Mac, run the following:

shell
brew bundle dump --describe --file=~/Brewfile

This command creates a Brewfile in your home directory, listing all installed Homebrew packages and casks.

Step 2: Transfer Brewfile to new Mac ​

Copy the Brewfile to your new Mac using AirDrop, USB drive, or cloud storage.

Step 3: Import Brewfile on new Mac ​

On your new Mac, run the following command to install all apps listed in the Brewfile:

shell
brew bundle install --file=~/Brewfile

This command reads the Brewfile and installs all specified applications and packages.

Additional tips ​

  • Delete unnecessary apps from the Brewfile before importing on the new Mac.
  • For Alfred users, the Homebrew Search workflow can help find and install apps quickly.
  • Regularly update your Brewfile to keep track of installed applications.
