• Test the connection: Verify that you can successfully connect to the device and access its command line.

The process often includes the following steps:

1. Visit the official website of your chosen SSH tool or client.
2. Navigate to the download section of the website.
3. Select the appropriate version compatible with macOS.
4. Click the download button to begin the installation.
5. Follow any on-screen prompts to complete the installation.

The choice between free and paid SSH tools comes down to your specific needs and budget. Free tools often provide all the essential functionalities for basic remote access and management. They might be adequate for personal projects or small-scale deployments. However, if you need advanced features, such as centralized management, advanced security features, or technical support, you might consider a paid solution. The paid options often provide a more polished user experience and may offer additional customization options.

Beyond just downloading and installing the tools, you must ensure the SSH service is running on your IoT devices.
