How to set up a network card connection in macOS

On Apple products, there are some restrictions on changing the MAC address. For example, on Windows or Ubuntu, you can specify the desired MAC and it will be with you until you change it yourself. On macOS, this feature is also available, but you can only change it for 1 session, which means that after rebooting your PC, you will need to change the MAC address again. This is very inconvenient, so we recommend contacting tech support to have a new MAC address registered for your connection.

There is also a question about the Ethernet port. For example, if you have an Apple monoblock, there should be no problem. But if you have a MacBook, you will not have the necessary connector. To connect without a router by cable, you will need to buy an external network card with RJ45 and USB connectors for the Internet cable. For example, as shown in the photo below.

If you have such a network card and you have connected it, then go to the Internet settings.

1. Click on the «Apple» icon in the upper right corner, then click on «System Preferences».
   
2. In the menu that appears, find the «Network» icon and click on it.
   
3. Find the line «USB Ethernet» and select the desired connection type «Using DHCP».
   
4. Next you need to check the current MAC address of the device and verify it with the one you should have. You can verify it by phone or chat with technical support. You can also check it in your personal cabinet in the «Services» — «Internet» section.
5. Tell technical support which MAC address to set. After that you will have an Internet connection via Ethernet cable.

You can check the received network parameters in this menu «Ethernet» — «Hardware».

If you click on the «Advanced» button, the advanced settings will open, where on the last tab you can see the MAC-address of the network adapter and connection speed — usually either 100 Mb or 1 Gb (depending on the characteristics of the cable and equipment).

Commands in the terminal

The terminal allows you to check the network parameters of your PC. You can view your IP and MAC address (physical address), check the availability of Internet resources and the stability of the connection.

1. Find the «Launchpad» icon on the panel and type «terminal» in the search. Enter the command to display the network settings.
   

   ifconfig

   
   
2. Check the availability of a resource (for example, your favourite website or game server). Your PC sends a request and receives a response from the required IP address. If all responses are received, it indicates a stable connection.

Perform a trace to the address of interest. This program can be used to collect and analyse your connection to specified addresses.

The last three columns that are displayed in the console are the response parameters for the three packets sent for tracing for each hop. As you can see in the picture above, we needed 11 hops to trace the route. The minimum response came from the first host — this is the first switch after the PC and the distance to it is minimal. As we move away from the trace point, the response delay increases.
