WD Security
WD Security is Western Digital's encryption and drive-protection utility for macOS, designed to secure data on WD and SanDisk external drives and storage devices. It provides hardware-based encryption, password protection, and drive unlock functionality to prevent unauthorized access. The app is commonly used by individuals and businesses protecting sensitive data on portable storage devices, offering features like automatic locking, RAID protection in some cases, and compatibility with WD's ecosystem of drives.
AI Recommendation
1 suggestionWD Security has not been updated to a native Apple Silicon build. The latest available versions (including 2.1.1.85) are Intel-only binaries according to the doesitarm.com database. Western Digital's own support pages confirm that Apple Silicon Mac users must install Rosetta 2 to run the app today. Since Apple is removing Rosetta 2 in macOS 28 (September 2028), WD Security will stop launching entirely on that release unless Western Digital ships a native build before then. Contact Western Digital directly to ask about native Apple Silicon support and get a timeline for when (or if) a native build will be available. Given the timeline — it is now May 2026 with about 27 months until Rosetta 2 removal — this is a good moment to press the vendor for clarity. If Western Digital confirms no native build is planned, begin researching alternative encryption and security solutions that run natively on your Mac, such as macOS's built-in FileVault encryption or third-party cross-platform tools that already ship with native Apple Silicon support.
