How do I find my Chromebook’s MAC address?
There are two ways to find your Chromebook’s MAC address.
Using the Networks panel near the clock
Visit Google’s Connect to Wi-Fi page.
Scroll down to Find the Media Access Control (MAC) address. Click to expand the section, and follow the instructions.
Using the browser’s “About System” diagnostic page
Open a browser window. In the address bar, type chrome://system, and press Enter.
Look for ifconfig, and then click the Expand… button next to it.
Look for either the eth0 section (wired MAC address) or the wlan0 section (wireless address). In both sections, the MAC address will be listed as the Ethernet HWaddr.
Note: If you haven’t set up your Chromebook and are seeing the Chrome “Welcome!” screen, there’s a third way to find the MAC address. On the welcome screen, below the Select your language: and Select your keyboard:drop-down menus, you will see a Select a network menu. Expand that menu to see the MAC address (or addresses, if your Chromebook also has an Ethernet port) listed at the bottom. If you have more than one MAC address, they will be identified as “Ethernet” (the wired connection’s MAC address) and “WI-FI” (the wireless connection’s MAC address).
How to find Chromebook Serial Number:
Hit (Esc + refresh + power) to start the wipe process
Hit (Ctrl + D) on the recovery screen (yellow exclamation mark)
Hit (Enter) on the screen that states: “to turn OS verification OFF, press enter. Your system will…”
On the next screen which has the red exclamation mark, let the system proceed to the next screen automatically.
Then, on the next screen which states: “The device owner has disabled developer mode for this device…” again, let the system reboot automatically
When the chromebook restarts you will be at the screen that states: choose your language and network, you don’t need to fill this out just hit (ALT + V) and the serial number will display in the top right corner of the screen.
