My Cloud OS, a proprietary operating system, is pre-installed on all My Cloud devices and facilitates management of the NAS's.[2] It provides a graphical user interface and offers customization options. Moreover, some users have identified that the operating system is based on Linux, sporting a user-friendly graphical user interface and SSH accessibility.

This operating system is proprietary. However, others have found the operating system to be Linux, with a graphical user interface, but also accessible.[3] It comes pre-installed on all My Cloud devices.[4]

My Cloud apps[edit]

My Cloud is designed to be compatible with various platforms, including personal computers, Apple Macs, Android devices, and iOS devices. Western Digital provides applications that enable interaction with My Cloud devices.[2][3][4]


On March 26, 2023 Western Digital encountered a cyberattack that led to unauthorized access to company systems and data theft. As a precautionary measure, the company temporarily suspended some services, including My Cloud on April 2. The suspension lasted for ten days, during which users were unable to remotely access files stored on their WD NAS devices. After the security assessment was completed, My Cloud functionality was restored.[5][6]
