Yes, you can absolutely use a Western Digital My Book hard drive for both Mac and Windows. How you set it up depends on which system you use most.

  1. If you use Windows most, use NTFS Format.

Windows supports full reading and writing out of the box. Mac can only read files from NTFS drives, not write to them. To get full read and write access on your Mac without erasing your data, you can install a third-party NTFS driver. [This article is helpful for you: How to choose a drive format for Mac and PC ? ]

  1. If you will use the hard drive on different Windows PC and Macs, set it to exFAT format.

If you do not want to deal with installing third-party drivers on every Mac you connect to, the best alternative is to reformat the drive to exFAT. This format is natively supported by both Windows and macOS for full reading and writing without extra software. Note: Formatting will erase all current data, so back up your files first.
