ChromeOS Developer Mode

ChromeOS is known for it's simplicity, security, and seamless integration with Google's ecosystem. It's designed to be user-friendly, allowing even those with minimal technical expertise to enjoy a fast and secure experience. However, beneath this polished surface lies a powerful side of ChromeOS that is less known to the average user: Developer Mode.

Developer Mode on ChromeOS unlocks a range of advanced features that transform the typically locked-down environment into a playground for developers, tech enthusiasts, and power users. It opens up access to the underlying Linux system, allowing users to run custom code, install Linux distributions, and introduce changes to the system that would otherwise be impossible in the default "verified-boot" mode. It is important to note that ChromeOS can run Linux Distributions without Developer Mode on most devices made after 2019 however if you are on an older device, Developer Mode will be your only option to run Linux Distributions.

If you are using a managed ChromeOS Device such as one that is issued by an employer or school, the ability to put your ChromeOS Device into Developer Mode may be blocked. Additionally some Android applications that require enhanced security, specifically devices that use The "Google Play Integrity API" may not function on devices in Developer Mode. The list of potentially impacted applications includes some streaming media applications, banking applications and password managers. 

Developer Mode is not recommended for users without a strong understanding of Linux as it unlocks the ability to run code and commands on the base operating system instead of being forced to use the safeguards built into the ChromeOS Shell (CroSH). ChromeOS Developer Mode essentially permits your ChromeOS Device to run Linux Shell commands as the super-user (root). This also allows you to perform changes to the ChromeOS Firmware that are otherwise not permitted. It is also possible to remount the read-only file system into read-write mode, which allows users to modify the base operating system.

This chapter will delve into the intricacies of Developer Mode, exploring its potential and guiding you through the process of enabling it. We’ll discuss the benefits and risks associated with Developer Mode, and how it can be used to tap into the full potential of your ChromeOS device. Whether you’re a developer looking to use your Chromebook as a coding platform, or simply curious about what lies beneath the surface of ChromeOS, Developer Mode offers a gateway to a richer, more customizable computing experience. This chapter will also cover the disadvantages of running ChromeOS in Developer Mode as it could significantly degrade the stability and security of ChromeOS.
