Having Python installed through Homebrew ensures that the Python environment is compatible with ARM architecture and that it will work smoothly with pymssql and other libraries. It’s important to make sure that Python’s path is correctly set up in your environment, as certain issues can arise if macOS defaults to an older version of Python.

Step 4: Installing FreeTDS – The Backend for pymssql

pymssql relies on FreeTDS, an open-source library that allows Unix-like systems to connect to Microsoft SQL Server databases. Install FreeTDS via Homebrew by running:

This command downloads and installs FreeTDS, including the necessary files for establishing a connection between pymssql and SQL Server. FreeTDS plays a crucial role in facilitating communication with SQL Server, making it an essential dependency for pymssql to function properly. Once installed, FreeTDS’s libraries will be accessible to pymssql, making it possible to connect Python applications to SQL Server on your M3 Mac.

Step 5: Verifying FreeTDS Installation on Apple M3

After installing FreeTDS, it’s essential to verify that the installation was successful and configured correctly. To do this, use the following command:

This command checks the version and configuration of FreeTDS on your system. If FreeTDS is correctly installed, you should see output with version details and configuration paths. This verification step ensures that FreeTDS is correctly set up and accessible to pymssql for SQL Server connections, which is particularly important when working on an ARM-based Mac.
