How to Write to NTFS Drive on macOS Catalina?

In October 2019, Apple released macOS 10.15 Catalina. As the latest update to the Mac operating system, it adds plenty of new features like the Apple Arcade gaming subscription service and Apple TV app, and makes useful improvements to photos, Notes, Reminders, and many of Apple’s other apps.

But that doesn’t mean it’s perfect, some problems existing in the previous macOS version remain the same with the latest macOS Catalina. One of them is the incompatibility issues between Microsoft’s Windows and Apple’s macOS. If you’ve ever tried transferring files between Window and Mac using an NTFS-formatted external disk, you might find that you can only view files stored on your external drive but cannot copy and paste or drag and drop files on to this disk. Why is an external hard drive read-only on Mac? This is due to Mac disables write support to NTFS drives by default.

Is there any way to write to NTFS drives on macOS Catalina? The article will introduce four effective solutions for you to write to NTFS drives on Mac.
