It’s important to understand the risks before proceeding. It disables many security protections and voids the warranty on most Chromebooks.

Enabling developer mode in an operating system (OS) often grants users advanced access and control, empowering them to modify system settings, debug applications, and perform various development-related tasks.



  1. Accessing Developer Mode:
    • Navigate to Settings by clicking the Start menu and selecting the gear icon.
    • Choose “Update & Security.”
    • Click on “For developers” from the left sidebar.

Using Developer Mode on a Chromebook gives you more control of the operating system. It is similar to jailbreaking an iPhone or rooting an Android device. Developer Mode allows you to sideload apps and install other operating systems on the device.

The process of enabling Developer Mode is simple, but there are risks involved. You should back up your local data and understand the consequences of turning on Developer Mode. You also lose all of the security features that are normally in place. It is not recommended for beginners, and it voids most of the manufacturer’s warranty.

One of the biggest risks is that the Chromebook could be sabotaged by hackers, resulting in the loss of personal information and files. You can enable Developer Mode on any Chromebook, including the newest devices. Fortunately, the process is easy to do and relatively safe if you follow these steps. It also allows you to unlock the full potential of your Chromebook.


In Chromebook   Mode, the device can be booted from any image, even if it’s not signed by Google. This allows tinkerers to run any arbitrary Linux program with root access.

Although this opens up a lot of possibilities, it also removes many security features and increases the risk that your device will be sabotaged. As such, it is only recommended for advanced users and developers that are familiar with the risks.

Enabling this mode will wipe your local data and disable all security features, so make sure you backup everything before proceeding. You’ll also need to enable Developer Mode each time you want to reboot the device, as it’s not permanent. To do this, press and hold the Esc + Refresh keys while pressing the Power button. This will open the Recovery screen and let you enable Developer Mode by pressing Ctrl+D. To exit the Recovery screen, press the Space key when prompted. It will then reboot to normal mode.


Once you’ve enabled Developer Mode, it’s possible to poke around on a command shell (as root if desired), install Chromium OS, or even try out other operating systems. Developer mode does disable some security protections, though, and it generally voids most Chromebook warranties so don’t enable it unless you’re an experienced tinkerer or plan to get warranty support for your device.

Fortunately, it’s easy to deactivate Developer Mode once you’re done with it. Just head to the Settings menu, find the Developer options, and click the toggle to turn it off. You’ll also need to restart your device before it reverts to normal mode. Be sure to back up your data before doing this, too, since disabling Developer Mode will also factory reset your device.


Developer Mode allows you to access advanced features and experiment with your Chromebook in a way that isn’t possible on any other platform. However, it also makes your device less secure and can lead to data loss. This is why it’s important to backup your Chromebook and understand the risks before enabling developer options.

It may seem strange that Google’s Chromebook has a setting similar to the one available on Android devices, but the two settings have different purposes. The Android version is designed to let users tinker with new features, while the Chromebook developer mode removes restrictions and gives people more freedom to install software on their devices (but still requires verification). If you want to return your device to its original state after enabling this mode, shut it down, turn off the battery, flip the switch, and restart. This process erases the stateful partition, which can take up to 40 seconds on some devices.
