Selling a used Western Digital My Passport for Mac 1 TB external hard drive.  Have used it for several years and it works great w/ no issues.  Auction includes the drive, USB cable, original box and quick install guide.  The drive has been erased and formatted to Mac OS Extended (Journaled).  Not sure if WD Security and WD Drive Utilities are still on the drive, they may be available on the drive when you go to install it, but if not then those applications can be downloaded from the Western Digital website. I have used this drive w/ Sonoma as well as earlier Mac OS.  Drive has passport protection w/ hardware encryption, is Time Machine compatible and uses a SUB3.0 cable.
