DiskBee

About

External drives and USB sticks from Windows show up read-only on Mac? DiskBee makes NTFS drives behave like native disks, no reformatting, no data migration, auto-mounted the moment you plug in.

Built on FSKit, the system-level file system architecture introduced in macOS 15.4: no kernel extension, no third-party plugin, no restart, no security lowering, and it survives macOS upgrades.

• Plug In & Read-Write: NTFS drives auto-mount on plug-in. Browse read-only for free; Pro unlocks full copy, edit, delete, and rename.
• BitLocker Drives: Unlock BitLocker-encrypted NTFS drives with a password or recovery key, read and write with real-time encryption, fully Windows-compatible.
• Native FSKit Engine: Built on Apple's official FSKit framework, the same technology as macOS's own file systems. No restart, no Recovery Mode, no security downgrade. Requires macOS 15.4+. Universal for Apple silicon and Intel.
• Check & Repair: Dirty volumes self-heal at mount via automatic log replay, with built-in unmount diagnostics. Four-level checks of MFT records, cluster allocation, and directory indexes; common errors are safely auto-repaired, and deep corruption is handed off to Windows chkdsk.
• Format to NTFS: Erase and format drives as NTFS via the built-in Disk Utility or diskutil, no third-party partitioning tools needed. Plus interrupted-copy cleanup and conflicting-driver detection.
• Windows Compressed Files: Transparently decompresses Windows-compressed (LZNT1) files, read, copy, and edit them as usual, no manual extraction needed.
• Disk Speed Test: CrystalDiskMark-style 4-profile benchmark (sequential/random × write/read) measured through the NTFS engine itself, real-world throughput with cache-defeating methodology, plus IOPS and latency.
• No Formatting · Free Lifetime Updates (no major-version upgrade fees): Use NTFS disks right away, no formatting, no data loss. New versions are free, with automatic checks and one-click upgrade.
