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
Setting up a Raspberry Pi from a Mac 22 June 2019; Compiling and using the uDMX command line utility, on a modern Mac 21 June 2019; Uninstalling a Mac kernel extension 31 May 2019; Starting or stopping Synology packages from the command line, or automatically on boot and shutdown 20 February 2019; Thirty 19 December 2018. Running Raspberry Pi Desktop is a great way to make use of an old computer that's not capable of running the latest version of Windows or macOS. Additionally, Raspberry Pi Desktop includes lots of software tools to get you started with coding and digital making. Warning: installing Raspberry Pi Desktop on a computer will delete all the data. Creating SD Card Images For Raspberry Pi in Mac By Phil South / May 25, 2015 Updated Jan 1, 2018 / Hardware Guides The Raspberry Pi is a new breed of cheap, single use computers that were just made for making projects.
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 :
Raspberry Pi Macbook
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 : https://coolnfiles377.weebly.com/software-mfj-multicom.html.

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 :
Raspberry Pi Mac Os
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:
Raspberry Pi Macro
Do you like the sleek look of Apple's laptops? Pixelmator pro 1 2 42. Are you a fan of the Raspberry Pi? Have a particular affinity for hot glue and 3D printed plastic? Then you're in luck, because this tiny 'MacBook' built by serial miniaturizer [Michael Pick] features all of the above (and a good bit more) in one palm-sized package. (Video link, embedded below.)
Getting the LCD panel and Raspberry Pi 4 to fit into the slim 3D printed case took considerable coaxing. In the video after the break, you can see [Michael] strip off any unnecessary components that would stand in his way. The LCD panel had to lose its speakers and buttons, and the Pi has had its Ethernet and USB ports removed. While space was limited, he did manage to squeeze an illuminated resin-printed Apple logo into the lid of the laptop to help sell the overall look.
The bottom half of the machine has a number of really nice details, like the fan grill cut from metal hardware cloth and a functional 'MagSafe' connector made from a magnetic USB cable. The keyboard PCB and membrane was liberated from a commercially available unit, all [Michael] needed to do was model in the openings for the keys. Since the keyboard already came with its own little trackpad, the lower one is just there for looks.
Speaking of which, to really drive home the Apple aesthetic, [Michael] made the bold move of covering up all the screws with body filler after assembly. It's not a technique we'd necessarily recommend, but gluing it shut would probably have made it even harder to get back into down the line.
We've previously seen [Michael] create a miniature rendition of the iMac and an RGB LED equipped 'gaming' computer using many of the same parts and techniques. He'll have to start branching off into less common machines to replicate soon, which reminds us that we're about due for another tiny Cray X-MP.
