Using My Passport drive for Time Machine backups, but I can't save other files to it

External Drives My Book

I recently purchased a 4TB My Passport Drive and use it for Time Machine backups on my Mac. I cannot save other files to it because I only have Read access, even though I have Administrator rights. Is this because it’s encrypted?

Thanks.

You can install third-party software like Paragon NTFS or Tuxera NTFS, which will allow you to write to NTFS drives from macOS.
