How do I encrypt my USB drive (Mac)?
To encrypt a USB for Mac, you will need to make sure the format of the drive is "HFS+" (How do I do that?) as this is the only format OS X supports for encryption.
If you need to format your USB, save the work elsewhere first as formatting will completely erase the drive. Drives formatted with HFS+ can only be used on Mac.
- Open Finder
- Right click the USB stick that you want to encrypt then select Encrypt "name-of-drive"
- Choose a password and a hint
- Click Encrypt Disk
- From now on the password will be required to open the USB
