WD Discovery
WD Discovery is a macOS desktop utility for managing supported Western Digital drives, updates, security settings, and connected storage features.
What is WD Discovery?
WD Discovery is a desktop utility for macOS that helps users manage supported Western Digital external drives from one place. It is commonly installed with products such as My Passport and My Book to show connected devices, available capacity, and free space, and to provide access to companion tools like WD Security and WD Drive Utilities. The app can help users register a drive, configure supported RAID features, and manage password protection on compatible hardware. It also offers update notifications and can import content from certain cloud storage and social media services to a WD drive. On Mac, users typically encounter WD Discovery when setting up a new drive or adjusting device settings after installation.

Safety overview
Status: Mostly safe
WD Discovery is legitimate drive-management software for supported Western Digital hardware. It may run at login, check for updates, access connected drives, and ask for administrator credentials during installation or updates, which is normal for storage utilities. If you use features that connect cloud accounts or install companion tools, review those permissions carefully and only sign in to services you intend to use. Removing the app can disable convenient drive management features, but it does not erase files already stored on your drive.
Recommendation: Keep WD Discovery if you use a supported WD drive and want an easy way to manage settings, updates, security features, or companion tools. If you no longer use WD hardware or prefer not to run its utility software, you can remove it; your existing files should remain on the drive, but app-based management features may no longer be available until you reinstall it.
