Does the WD My Passport for Mac work with Time Machine?
Yes. Western Digital ships it Time Machine ready, so macOS recognizes it as a backup target without reformatting or installing extra drivers.

It is designed and formatted for Mac. Using it on Windows generally requires reformatting the drive, which erases existing data. Check the product listing for the exact shipping format.
Is the data on the drive encrypted?
Yes. The drive includes password protection with hardware encryption, so files stay locked without relying on macOS FileVault.
