Before you create a new folder on an external hard drive, it's important to make sure that the drive's file system is compatible with your Mac. To do this, open Disk Utility and select the drive. From there, you can view the file system of your external drive under the disk name.

If it reads "Windows NTFS," you'll need to enable full support for NTFS on Mac ahead of proceeding. Otherwise, you can't create a new folder on the external hard drive on Mac because the "New Folder" option will be grayed out or missing.

The NTFS format is the primary reason why many users can't create a new folder on an external hard drive on Mac. While macOS can read NTFS-formatted drives, it can't write to them by default. Fortunately, there are third-party NTFS for Mac drivers that address the issue.

iBoysoft NTFS for Mac is such a tool that grants you full read/write access to NTFS drives on Mac. It can automatically mount NTFS drives in read-write mode without the need to relaunch. This allows you to work with the NTFS drive as if it were a native Mac hard drive, enabling you to write data to it freely.
