How to read a Mac drive on Windows 10 and 11

You plugged a drive from a Mac into a Windows PC and nothing useful happened: no drive letter, or a prompt to format it. The drive is almost certainly fine. Windows simply has no built-in support for the two Mac formats.

First, do not format the drive. If Windows asks "You need to format the disk before you can use it", choose Cancel. Formatting would replace the Mac file system with an empty Windows one. Why Windows asks

Which format is the drive?

Macs format drives in one of two file systems. Apple describes APFS as "the file system used by macOS 10.13 or later"; older drives, and many Time Machine disks, use Mac OS Extended, also called HFS+. Apple lists only "MS-DOS (FAT) and ExFAT" as the formats "compatible with Windows" (Apple Disk Utility guide). If you do not know which one your drive uses, an app that reads both saves you guessing.

The three ways to open it

A file system driverMacDrive, Paragon APFS or HFS+ for Windows. The drive gets a letter in File Explorer.Working from the Mac drive every day, reading and writing.Installs a driver; paid; the drive can be changed by Windows and by you.
A reader appDiskferry, TransMac, UFS Explorer, HFSExplorer. You browse the drive in the app and copy files out.Getting your files off once, safely.No drive letter; most are read only (that is the point).
A workaround7-Zip for disk images, or booting Linux with apfs-fuse.Free, if you are comfortable with the tools.Limited format support and silent failures in our tests. Details

The read-only way, step by step

Diskferry reads APFS and Mac OS Extended drives without a driver and never writes to them. Looking is free, so you can check that your files are there before paying anything.

  1. Plug in the Mac drive

    If Windows offers to format or initialize it, choose Cancel.

  2. Click Find Mac drives

    Windows asks once for administrator permission. A small helper opens only disks that carry a Mac partition, read only, hands them to Diskferry and exits.

  3. Browse the volume

    Each drive gets a card with its Mac volumes, their format and size. Click Browse, open folders and click a file to preview it.

  4. Copy out and verify

    Tick files or folders (nothing ticked copies the whole folder), choose a folder on your PC and copy. Every copy is read back and compared by SHA-256.

Browsing and previewing are free. Copying files to the PC is a one-time US$14.99 unlock, no subscription.

What Diskferry does not do

Not in this version: writing to the drive, drive letters in File Explorer, the internal SSD of Macs with a T2 or Apple silicon chip, Time Machine backups, Fusion Drives and encrypted or compressed .dmg files. If you need the drive to show up in File Explorer and to write to it, a driver is the right tool; see MacDrive and Paragon.

Questions

Can Windows 11 read a Mac drive without extra software?

No, not an APFS or Mac OS Extended drive. Windows reads FAT, exFAT and NTFS; Apple itself lists only FAT and exFAT as the Disk Utility formats compatible with Windows. You need a driver or a reader app.

Will opening the drive on Windows damage it?

Reading does not change anything, but a driver mounts the drive for writing, and Windows itself may offer to format it. Diskferry opens the drive with read access only, so nothing on it can change.

Can I use the drive on the Mac again afterwards?

Yes. As long as you do not format it, the drive stays exactly as the Mac left it.
