Mac Os For Raspberry Pi

Posted onby admin

Installing an Operating System on Your Pi. Insert your newly created SD Card into your Raspberry Pi and insert the power cable to turn it on. NOOBS will run automatically, first resizing the FAT (File Allocation Table) partition and formatting the settings partition, launching into a graphical user interface (GUI). Using Raspberry Pi Imager. Raspberry Pi have developed a graphical SD card writing tool that works on Mac OS, Ubuntu 18.04 and Windows, and is the easiest option for most users as it will download the image and install it automatically to the SD card. Download the latest version of Raspberry Pi.

It can sometimes be useful to obtain the MAC address of your Raspberry Pi’s network interfaces. The “Media Access Control” address is a unique identifier given to all networked devices. The address is different for all Pi’s and can be used to identify your device. Think of it as a digital fingerprint. There is a separate MAC address for Ethernet and WiFi interfaces.

There are a number of ways to identify them using the command line or using Python code. Below are some quick examples you can use to find the MAC address.

From the Command Line

To find the MAC address from the command line you need to know the name of the interface. The Ethernet interface used to be called “eth0” but in newer versions of Raspbian it may be “enx########” where ######## is the MAC address. This means the Ethernet interface name is unique for every Pi. The first WiFi interfaces is still named “wlan0”.

You can find the interface names by using :

The name will be one of the displayed sub-directories alongside “lo”.

You can then use the following command :

or you can type :

You should swap #### for the interface name.

This will result in output similar to :

or

The “HWaddr” or “ether” value is the MAC address. In this example “c7:35:ce:fd:8e:a1”

Finding the Ethernet Interface Name Using Python

The names used for the Ethernet and wireless interface on the current version of Raspbian are “eth0” and “wlan0”.

In some older iterations of Raspbian these names were based on the MAC address of the interface using what is known as “predictable interface names”. For this reason I created a function to determine the name regardless of the scheme being used :

It looks at the sub-directories of /sys/class/net/ and finds either “eth0” or the name starting with “enx”.

In your script you could use this function to read the interface name into a variable :

Finding the MAC Address Using Python

The following Python function can be used to obtain the MAC address of your Raspberry Pi :

This function can be called using the following line :

Or if you have a WiFi connection :

Finally combining both functions would give you ability to find the Ethernet interface name and then retrieve the address without worrying about what version of Raspbian was being used:

To connect to a Raspberry Pi using SSH or VNC, you need to know the Pi’s IP address.

If you use the Raspberry Pi with a monitor, you can check the Pi’s IP from the command line (terminal) by executing the hostname -I command.

Without a monitor and keyboard (headless) you can find the Raspberry Pi’s IP if you connect it to LAN (Local Area Network).

In this note i will show how to find the Raspberry Pi’s IP on network.

MAC Address Lookup: MAC addresses of the all devices of Raspberry Pi Foundation start with B8:27:EB:xx:xx:xx or DC:A6:32:xx:xx:xx.

Find Raspberry Pi’s IP on Network

Connect the Raspberry Pi to your local network and use one of the following commands, depending on your operating system, to find the Pi’s IP address.

Windows command prompt:

MacOS or Linux command line:

Alternatively, you can find the Raspberry Pi’s IP using nmap command, but the solution with arp is much faster and does’t require installation of additional software:

Subnet: Replace 192.168.1 with the subnet for your LAN if it’s different.

Ping all IP addresses on LAN

If you have connected a Raspberry Pi to the network recently, the ARP table may not contain the Raspberry Pi’s IP and MAC addresses, as to be recorded Raspberry Pi has to send at least one packet to your computer.

To force this we can simply ping all IP addresses on LAN.

MacOS or Linux command line:

As only the computer receives a response from Raspberry Pi, it records IP and MAC addresses in the ARP table and you can run the arp commands above to find them out.
