CrossDriver

CrossDriver is a Hong Kong-based high-tech enterprise specializing in kernel-level and system-level cross-platform software solutions. We are committed to delivering high-performance, highly reliable underlying system technologies, making cross-platform data interaction and management simple and effortless.

CrossDriver focuses on R&D of cross-platform file system drivers and underlying storage technologies. We have long delved into file system interoperability across Windows, macOS and Linux, dedicated to breaking down data barriers between different operating systems.

The company independently develops core driver technologies. We have launched professional products surrounding file systems including NTFS, Ext4 and XFS, and continue to explore more complex file systems such as BTRFS and ZFS. We build cross-platform data solutions covering individual users, creative professionals and enterprise clients, delivering stable, efficient and secure data read-write services for users worldwide.

Core Competencies

- Strong technical expertise: The team boasts 15 years of macOS driver development experience, 20 years of Windows development experience, 15 years of Linux development experience, plus mature QT/QML UI development capabilities.
- Kernel-level performance: Our self-developed NTFS for Mac / Ext4 for Mac / XFS for Mac delivers over 5× faster transfer speeds compared with FUSE-based user-space tools, outperforming globally renowned alternatives. Full feature support for NTFS, Ext4 and XFS is available.
- Platform-based architecture: Modular design enables rapid adaptation to BTRFS and ZFS, shortening development cycles and boosting efficiency.
- Global footprint: Self-built multilingual sales platform supporting online payments in more than 170 countries and regions worldwide.

We are more than tool developers. We break barriers between operating systems to make cross-platform workflows simpler and more efficient.

Our R&D team specializes in macOS file system development, kernel debugging and low-level driver engineering, with extensive experience in Mac file system frameworks and system kernel optimization.

Unlike traditional FUSE solutions, CrossDriver drivers run directly within the macOS kernel layer and interact with the system at the lowest level. This drastically cuts down data conversion processes, enabling NTFS/Ext4/XFS file systems to achieve performance close to Mac native file systems.

Benefits brought by this architecture:

- More stable file reading and writing
- Faster data transfer speeds
- Lower CPU consumption
- Smoother macOS system responsiveness
- Superior handling of large files

Upcoming Offerings
4. CrossDriver App**: A lightweight Windows application compatibility layer built for Apple Silicon macOS. It is not full-machine virtualization. Instead, it reconstructs the runtime environment required by Windows applications on top of macOS — so Windows-only software can launch directly in windows on your Mac desktop. Similar to Crossover with improvements in certain aspects. Stay tuned!
