Hi, I have a NEW WD My Passport drive. I am not sure if it was only for a PC but It had Mac Discovery app on it to so I thought it would work with a Mac so I did not reformat it in Exfat.
other wise I would have formatted it in exfat for use with PC and Mac.
So this drive is Formatted in NTFS from WD Factory.
I copied files onto it from my Win-10 PC so I know the drive is working correctly.
It actually works really good. Better than I thought.
But Now I want to copy files onto it from my Mac but I think because it is formatted in NTFS
I can not copy from my Mac to the WD.
Well, most external hard drives are designed to work for Windows computers. Windows was mainly optimized for NTFS (New Technology file system) format, on the other hand, APFS was created for the Mac OS. NTFS is not compatible with Mac and similarly APFS does not get along with Windows. So if you’re trying to connect an external hard drive to a Mac, you might have to format the drive before you can use it.
Further, I suggest you to check the below link that explains all the methods to format your external drive for mac without any data loss:
