Course Overview
Hi, welcome to my course, macOS Support: Network Configuration. My name is Herta Nava. I am an IT localization consultant working in a variety of exciting projects, from digital marketing, web design and development, to software localization. I am also a certified Apple support professional and a very enthusiastic author at Pluralsight. Developing skills to support Mac users will enhance your professional opportunities as a service technician, technical coordinator, or advanced user, both if you intend to work as an independent consultant or in an enterprise setting. On the other hand, this course can help you prepare to take the examination to become an Apple certified support professional. The Apple training and certification program is a very important path you would want to pursue because it will keep you at the forefront of Apple technology, and it will help you stand out from the crowd. In this course, we are going to see the topics related to network configuration in computers running the Mac operating system. The main topics we will cover include a review of fundamental network-related topics and concepts, a review of concepts related to network configuration specific to the Mac operating system, network configuration, the advanced network configuration options available, and finally, network connectivity and troubleshooting through the variety of tools offered by the macOS system to quickly help you solve any issues. By the end of this course, you will have the skills and knowledge required to support Mac users with regard to network connection and configuration, and you will know the tools you can take advantage of for a smooth and effective network configuration management. Before beginning the course, it would be very recommended to take, or have taken the previous courses in this series, which you will find here in the Pluralsight library. Please join me on this journey to learn all about network configuration in Mac with this course, right here at Pluralsight.

Network Configuration Specifics
Mac hardware offers a wide range of network connectivity options. In this module, we will see what networking interfaces and protocols are specifically supported by default in macOS. What we will see are hardware interfaces, cellular connections, virtual network services, and network protocols.

Advanced Network Configuration
In this module, we will see the advanced configuration options for the most common network preferences. MacOS does this automatically in general, but as support specialists, we need to be familiarized with the options available. The topics we will cover are the configuration settings, where we will see how to verify the current settings, the manual TCP/IP configuration, the advanced Wi-Fi configuration, 802. 1X configuration, NetBIOS and WINS, network proxies, the manual Ethernet configuration, and how to configure a VPN. As we have seen in an earlier module, most of the time TCP/IP and DNS are configured by the DHCP or PPP service automatically. In macOS the default configuration for Ethernet and Wi-Fi services launches the DHCP process automatically as soon as the interface becomes active. To verify this, simply select the service from the Network preferences and check that the configuration is using the DHCP service. In the same manner, other network service interfaces that require a manual connection, like Wi-Fi, VPN, or PPPoE, automatically use DHCP or PPP processes to obtain the TCP/IP and DNS configuration. You can also verify the TCP/IP and DNS settings with these interfaces or other interfaces in the same way as before, by selecting the service from the list, and then clicking Advanced in the Network preferences. You will see the details related to the TCP/IP or DNS configuration by selecting the appropriate tabs.

Network Connectivity and Troubleshooting
In this module, we will see the most common network connectivity issues and what are the tools available to us as support specialists to troubleshoot those issues and successfully resolve connectivity and network problems. We will see which are the general network issues that usually cause the problems, and the troubleshooting tools in macOS that can help you identify the problems and solve them. Let's start by reviewing the most common network issues. There are many things that can go wrong in terms of network, so it is necessary to try to isolate the problem. I also find it very effective to eliminate the most common and usual suspects before attempting more complicated solutions. The network issues that can occur can be perhaps best isolated like this, as local, network, or service issues, and the usual suspects are the Ethernet hardware, the Wi-Fi signal, DHCP service, and the DNS service. Local issues are typically related to incorrect local network settings or disconnected services. In the case of network issues, many elements can be involved, and this is why it's difficult to isolate them. This can range from a failing Ethernet port on a network switch or router modem, to more complex issues. In this case, the network diagnostic utilities macOS offers will be of great assistance. And in the case of service issues, these are related to the network device or service attempting to be accessed. For example, if DHCP or DNS are temporarily down or configured incorrectly. To quickly verify if the problem is a service such as DHCP or DNS, you can use the macOS diagnostics tool to verify if the services are working. We will see how that works in a little bit.
