Features
One focused app for the everyday jobs that macOS makes harder than they should be.
When running, the app automatically activates Windows/NTFS external drives as soon as they are connected.
Crossdisk automatically detects removable, external and internal drives the moment they connect, and keeps the list in sync as devices change.
See the details that matter: name, connection type, capacity, used and free space, partition scheme and current file system.
Mount a selected volume with a single click so it becomes available in Finder and to your apps.
Safely unmount and eject volumes to avoid data corruption before you unplug a drive.
Format drives to APFS, Mac OS Extended, exFAT or FAT32, choosing the layout that fits how you work.
Reliable NTFS operation with macFUSE and ntfs-3g installed. Full read and write support for external Windows drives.
Crossdisk works entirely on your computer. No account, no cloud, no telemetry, no tracking.

Modern macOS drives and SSDs
Apple File System — the default for recent macOS versions, with snapshots and strong space efficiency.
Older macOS setups and Time Machine
Also known as HFS+. A good choice for mechanical drives and legacy macOS compatibility.
Sharing between macOS and Windows
Cross-platform read/write on both macOS and Windows with no extra software. Ideal for large external drives.
Maximum device compatibility
Works almost everywhere, including cameras and older devices. Note the 4 GB per-file size limit.
NTFS read/write is available only when macFUSE and ntfs-3g are installed. It relies on that third-party software and is not a native macOS capability.
How It Works
From plugging in to safe ejection in four simple steps.
Plug in a USB stick, external SSD, hard drive or card reader. Crossdisk is ready the moment macOS sees the device.
The drive appears in the list right away, with its capacity, file system and mount status shown clearly.
Mount or unmount volumes, review drive details, or format to APFS, Mac OS Extended, exFAT or FAT32 when you need a fresh start.
When you're done, eject with one click so every volume is unmounted cleanly before you unplug the drive.
Crossdisk keeps everything on your Mac. There is nothing to sign up for and nothing sent away.
Built specifically for the Mac, so it looks, feels and behaves the way you expect from a first-class utility.
No account, no email, no activation. The app is yours to use the moment it finishes downloading.
No cloud, no telemetry, no tracking and no advertising. Your drives and your data stay on your machine.
We describe exactly what Crossdisk does — including that NTFS read/write depends on macFUSE and ntfs-3g.
A few of the questions we hear most often.
Yes. Crossdisk is completely free to download and use. There is no trial, no subscription and no paid tier.
No. Crossdisk requires no account, no registration, no login and no personal information. Download it and start using it immediately.
Crossdisk can attempt NTFS read/write mounting only when the third-party tools macFUSE and ntfs-3g are installed on your Mac. NTFS read/write is not a built-in capability and depends entirely on that software being present and configured.
Crossdisk can format disks as APFS, Mac OS Extended (HFS+), exFAT or FAT32. Choose exFAT to share large files between macOS and Windows.
Yes. Formatting permanently destroys all data on the selected drive. Always back up important files first and double-check that you have selected the correct drive.
