How to Encrypt a USB Drive for Use on Mac & Windows

I want to encrypt a USB (preferably on Mac) for use on both Mac and Windows without using third-party software. I've tried using Disk Utility on Mac but can only format the drive to non-encrypted DAT32 or exFAT as APFS (encrypted) is not readable on Windows. And formatting and encrypting the USB with VeraCrypt on Mac makes it not work on Windows. I also tried using BitLocker to encrypt the drive on Windows, but it doesn't work on Mac. So, what should I do?

I'm very sure that there's no native program that supports cross-platform full disk encryption up to now. Only using third-party tools can make that achievable.

As you say that you want to encrypt a USB on Mac for use on both Mac and Windows, you are recommended to use iBoysoft BitLocker for Mac. This tool allows you to encrypt a USB, HDD, SSD, SD card, or other storage device with the Windows BitLocker method and also unlock BitLocker-encrypted drives.

Here are the highlights of iBoysoft BitLocker for Mac:

  • Support encrypting drives using BitLocker on macOS Ventura, Monterey, Big Sur, and earlier.
  • Support encrypting drives using BitLocker on Intel and M2, M1, M1 Pro, and M1 Mac-equipped Macs.
  • Support BitLocker encrypting a drive formatted with NTFS, FAT, FAT32, and exFAT file systems.
  • Allow unlocking BitLocker-encrypted drives and read-write access to them on Mac.

Here's how to use iBoysoft BitLocker for Mac to encrypt your USB for use on Mac and Windows PC:
