WD Security Installer
WD Security Installer is a utility from Western Digital that installs and manages WD Security, a full-disk encryption tool designed to protect data on external hard drives and USB devices. The installer configures encryption settings, manages security credentials, and ensures the encryption software is properly deployed on WD-branded storage devices. It is primarily used by users of WD external drives who need to secure sensitive data with password protection and AES encryption.
AI Recommendation
1 suggestionWD Security Installer is an Intel-only application with no reported native Apple Silicon build. The most recent versions examined (2.1.1.81 and 2.1.1.85) both ship as 64-bit x86 binaries with no arm64 support. Western Digital has not announced a native build or any public timeline for one. The installer will continue to run under Rosetta 2 today, but Apple is removing Rosetta in macOS 28 (September 2028), at which point this app will no longer launch. Contact Western Digital support directly to ask about a native Apple Silicon build or alternative encryption solution for your WD external drive. If you rely on WD Security regularly, start planning now to either confirm a native version is coming or identify a compatible third-party encryption utility (such as macOS Finder's built-in AES-XTS encryption for external drives, or third-party tools like Cryptomator) as a contingency before September 2028.
