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.
Fix 1: Format the drive for Mac and PC compatibility
There are file systems well supported by both Mac and Windows PC, and they are FAT32 and exFAT. As long as you format your external hard drive specifically to these 2 file systems, it can be shared between Mac and Windows.
Note: The following method will erase all your data stored on your drive. Please make a backup of your important data first.
1. How to Format the Drive on Mac?

Step 2: Open Disk Utility. Open the computer window. Open a Finder window, click Applications in the sidebar, double-click the Utilities folder, and then double-click Disk Utility.
Step 3: Select the drive you want to format from the left sidebar.

Fix 4: Enable Writing to NTFS Using Terminal
Writing to NTFS drives is a functionality that has been built into in previous OS X. However, it has long been hidden for a long time. That indicates you can enable NTFS write support.
Note: this method has not been officially supported by Apple, so it might report errors, corrupt your data, your disk and cause data loss. Please back up your important data and run the following steps with caution.
Step 1: Go to Finder > Application > Terminal to launch Terminal.
Step 2: In the Terminal window, type in the following command line and press Enter.
sudo nano /etc/fstab
This will open the fstab files using the nano text editor. You will need to enter the administrator password.
Step 3: After that, you will see a new window with nothing. Simply paste the following command.
LABEL=DRIVE_NAME none ntfs rw,auto,nobrowse
Remember to replace the DRIVE_NAME with your NTFS drive name. Press CTRL + O to save changes and CTRL + X to exit.
Step 5: Restart your Mac. From the Finder menu bar, click Go > Go to Folder and type in /Volumes. Then locate your NTFS drive and access it.
