Full NTFS Read-Write on Mac

Because the drive is formatted as NTFS, Windows' file system, and macOS only supports reading NTFS by default — not writing. Once you install DiskBee, NTFS drives auto-mount as fully writable: copy, edit, and delete files without limits.

This is the classic symptom of an NTFS drive mounted read-only on macOS: you can see your files, but every write operation — drag-and-drop, paste, new folder, delete, rename — is blocked by the system. No reformatting needed: install the app and write directly, with all existing data preserved.

No. Reformatting to exFAT does enable writing on Mac, but it erases everything on the drive. DiskBee adds native NTFS write support to macOS via a system extension — your data stays exactly as it is, plug and play.

macOS 15.4 or later (including macOS 26 Tahoe and macOS 27), on both Apple Silicon (M1/M2/M3/M4/M5/M6) and Intel Macs. That's the only requirement — no restart, no Recovery Mode, no lowering system security.

All Apple Silicon and Intel Mac models are supported. As long as you run macOS 15.4 or later, every Mac works: MacBook Air, MacBook Pro, iMac, Mac mini, Mac Studio, and Mac Pro — on Apple Silicon (M1/M2/M3/M4/M5/M6) and Intel alike. External HDDs and USB flash drives of all brands are supported.

No. Legacy NTFS drivers on Apple Silicon require entering Recovery Mode, lowering system security, and restarting before they can work. We skip all of that: install and you're done — your Mac's security protections stay fully intact.

Choose "Uninstall DiskBee" in the app menu and confirm — the app and its system extension are removed cleanly, with no leftovers and no impact on your disk data. You can also move the app to the Trash and restart your Mac.

The free version offers NTFS read-only access, mount management and BitLocker drive unlock (read-only browse & copy-out) forever — no time limit, no activation required; the website download edition also includes the four-level disk structure check. Activating Pro unlocks full read-write, BitLocker read-write, the disk speed test and volume renaming, and in the website download edition additionally unlocks safe repair, formatting as NTFS and interrupted-copy cleanup. Try the free version first to confirm compatibility, then buy with confidence.

Never. All disk read/write and diagnostics operations run entirely on your Mac — we never collect or upload any file contents, file names, or directory structures from your drives. We only collect the device fingerprint (device SN and UUID) needed to complete transactions, plus device technical info for product improvement that never includes volume names, disk serial numbers, or any file content. See the privacy policy on the Legal page for details.

The app writes strictly according to the NTFS specification and adds confirmations and warnings for critical actions like ejecting. Normal use will not harm your disk or data.

The Software is a digital download and is not covered by unconditional return policies — the free version already offers full read-only access, so please verify compatibility before purchasing. If you encounter an unresolvable quality issue (e.g., activation failure or the Software not functioning), contact support within 7 days of purchase; once our technical team confirms the issue cannot be fixed, the refund is returned via the original payment method.

One license binds to a single device (identified by its device fingerprint). Purchase happens inside the app with no email and no license key — activation is automatic once payment succeeds. Reinstalling macOS does not affect activation.

Yes. Your activation status is stored locally, and read/write permission is verified entirely on your Mac with no network involved. Once activated, you can read and write NTFS drives without any internet connection—on a plane, on the road, anywhere. Only the initial activation and device transfers require an internet connection.

Yes — fully self-service and free. If your old Mac still works: open NTFSProKit on it → Settings → License → "Transfer to a New Mac" to unbind, then activate on the new Mac with the same license key. If the old Mac is lost or broken: in the new Mac's activation window choose "Transfer by order number", then enter the payment order number (found in your payment receipt) and the old Mac's serial number. Each license includes 5 transfers in total; for special cases, contact support at service01@mc-cwin.com.

Each order includes 5 free self-service transfers in total (one-click unbind on the old Mac plus order-number transfers combined), enough for years of normal upgrades. If you run out, contact support for manual help. Transfers do not reset the 7-day refund window.

No. A license key is bound to a device's hardware fingerprint (serial number + UUID) and can only be active on one Mac at a time; entering it on another device reports “bound to another device”. Keep your key and order number private — they are also your transfer credentials.

No. As long as it's the same Mac, open the app and click “Recover purchase & auto-activate” to restore without entering a key (matched by device fingerprint), or re-enter your original key in the activation window.

No — that's NTFS's own system files, not leftover data. Every NTFS volume pre-creates several system areas at format time: the journal $LogFile (enables recovery after power loss or unsafe ejection, 2–64 MB depending on capacity), the Master File Table $MFT (tracks where every file lives, about 2 MB initially), plus the allocation bitmap $Bitmap and the Unicode upcase table. On a 128 GB disk these total roughly 70 MB; formatting NTFS on Windows shows the same used space. These areas are zeroed during formatting, contain no old data, and don't meaningfully reduce your usable capacity.

The macOS 15.4 requirement is the precondition for building on Apple's official FSKit user-space file system framework (introduced in macOS 15.4): that is exactly why it needs no kernel extension, no SIP disabling, no lowering security in Recovery Mode, no restart after install, and why it survives OS upgrades — while before 15.4 only Apple's deprecated kernel-extension route existed. Any Mac that can upgrade to macOS Sequoia (15) can reach 15.4 and install the app; older Macs that cannot upgrade still read and copy NTFS files for free (macOS reads NTFS natively), and for writing can weigh a kernel-extension solution or offload to a Windows PC.

Yes — unlock and read-write. DiskBee includes a built-in BitLocker engine: enter the password or the 48-digit recovery key to unlock and read-write BitLocker-encrypted NTFS volumes created by Windows 7 and later (XTS-AES 128/256 and AES-CBC compatibility mode). The free tier unlocks the volume for read-only browsing and copying files out; Pro unlocks full read-write. Not supported: BitLocker To Go (encrypted FAT32/exFAT USB sticks), volumes with paused encryption or decryption, and volumes protected only by TPM with no password or recovery key.
