When you plug your removable NTFS drives into a Mac, they look good until you need Mac to write to NTFS drives. You notice that you can read the files on the drive, but you can't edit them. Nothing happens when you want to save files onto it.
Before you convert NTFS to APFS to make the drive compatible with the Mac running macOS 10.15, read this post first. This post will tell you why your Mac cannot write to NTFS drives and teach you how to enable NTFS writing on macOS Catalina and earlier.
You must encounter one of the most common problems in file transfer between Windows and macOS using a removable drive: the Winodws NT File System is not fully compatible with macOS.
macOS 10.15 (Catalina) was released on October, 2019. You could encountered some problems after you updated to macOS Catalina. Except for losing files after macOS upgrade, allowing Mac write to NTFS drives is another problem you should consider in macOS Catalina.
Can I use Windows NTFS drives on macOS 10.15?
Yes. You can use NTFS drives on macOS Catalina but only with read permission. Mac can read NTFS-formatted drives but can't write to them.
To understand the cross-platform incompatibility issue between an NTFS drive and a Mac computer, you should know about file systems.
A file system is a way of organizing and storing files on drives including internal hard drives, external hard drives, USB flash drives, and memory cards. It decides what information is attached to a specific file, like filename, file size, etc. There are a few file systems out there a drive can be formatted into, such as FAT, FAT32, exFAT, NTFS, APFS, etc.
Windows NTFS (New Technology File System) is the default file system used in Microsoft's Windows 10/8/7/Vista/XP, Windows 2000 and Windows NT operating systems. USB flash drives, external hard drives, SD memory cards can be formatted into NTFS too. How to Read and write NTFS external hard drives on a Mac is the one of the most asked questions.
The Mac operating system recognizes the NTFS file system and files in it but doesn't have the ability to write to it.
Even equipped with many new features, the NTFS write support that Mac users have wanted for a couple of years still is not available in macOS 10.15. It is kind of disappointing that Apple still doesn't make NTFS compatible with macOS 10. 15 again.
Interestingly, Windows doesn't support APFS (the default file system after macOS High Sierra and later) either. You can't read and write to an APFS drive on Windows.
We don't know why Apple and Microsoft haven't held the hands yet to make NTFS drives or APFS drives compatible with both Windows and macOS. The priority for users in this post is to know how to use the NTFS drives on macOS 10.15 and earlier.
Is there a way that you can use NTFS drives on Apple computers?
