Core Features

Powerful and rock-solid disk management engineered for macOS

100% Userspace (Zero Kernel Extensions)

Powered by modern FUSE-T over local NFS v4 protocol. Runs completely in userspace without requiring third-party kexts, keeping System Integrity Protection (SIP) untouched and eliminating kernel panics.

Format Any External Drive to NTFS on Mac

Bypass macOS Disk Utility limitations. Easily erase and format non-NTFS external USB thumb drives, SSDs, and mechanical hard drives directly into clean, standard NTFS format.

Auto-Mount on Plug-in

Plug in your external drive and start working right away. Partitions mount automatically with full read and write access without running manual terminal commands.

Fast, Native Transfer Speeds

Optimized for both Apple Silicon (M1–M4) and Intel Macs. Copies large 4K video clips, virtual disk images, and massive project archives at native hardware speeds.

NTFS First Aid & Repair

Diagnose volume health and fix dirty bit errors caused by unsafe disconnections on Windows PCs, restoring write access without wiping your data.

One-Click Batch Eject

Safely unmount all connected external disks with a single menu bar click to protect filesystem headers before pulling cables.

Auto-Mount & Direct NTFS Formatting

No Windows machine nearby? Plug in your drive, format it to NTFS in seconds, and start transferring large files across platforms without hitting FAT32's 4GB ceiling.

First Aid · Partition Erase

Zero Security Degradation (SIP Untouched)

Forget holding the power button to boot into Recovery Mode or lowering security policies. NTFSSync runs entirely in userspace, making it fully safe for personal setups and corporate MDM devices.

When Do You Need NTFSSync?

Overcome everyday external storage roadblocks on Mac

NTFS Drives Are Read-Only on Mac

You plug in a colleague's or client's Windows drive, but Finder blocks dragging, editing, or saving files onto it.

Need to Format a USB Drive to NTFS

macOS Disk Utility cannot create NTFS partitions. You need a Windows-ready drive without hunting for a PC.

Unwilling to Downgrade M-Series Security

Tired of older drivers forcing you into Recovery Mode to enable reduced security just to read an external disk.

Company Mac Blocked by IT Policies

Corporate MDM profiles strictly prohibit installing kernel extensions, rendering legacy NTFS tools unusable.

Full read-write access plus direct NTFS formatting for non-NTFS external drives

Automatic plug-and-play mounting at full hardware bus speeds
