Perform the following steps to install yb-voyager using brew for macOS:

1. Tap the yugabyte Homebrew repository using the following command:

   brew tap yugabyte/tap
   

   The repository contains the formula to build and install yb-voyager on your macOS device.

   Note that the tap yugabyte/yugabytedb has been updated to yugabyte/tap. If you have previously installed yb-voyager using the tap yugabyte/yugabytedb, untap the entry using brew untap yugabyte/yugabytedb, and then tap using the preceding command.

2. Install PostgreSQL 17 (required for pg_dump and pg_restore) using Homebrew:

   brew install postgresql@17
   

   After installing PostgreSQL 17, Homebrew displays instructions on how to add the PostgreSQL 17 binaries to your shell's PATH. These steps vary depending on your system's Homebrew installation path (for example: /opt/homebrew or /usr/local) and the shell you are using.

   1. Update your PATH by following the exact instructions shown by Homebrew. Following is an example of what Homebrew may display:

      If you need to have postgresql@17 first in your PATH, run:
      echo 'export PATH="/opt/homebrew/opt/postgresql@17/bin:$PATH"' >> ~/.zshrc
      For compilers to find postgresql@17 you may need to set:
      export LDFLAGS="-L/opt/homebrew/opt/postgresql@17/lib"
      export CPPFLAGS="-I/opt/homebrew/opt/postgresql@17/include"
      

   2. After the update, restart your terminal and verify that both report to PostgreSQL 17:

      pg_dump --version
      pg_restore --version
      

3. Install yb-voyager and its dependencies using the following command:
