|Managing Mac endpoints / About SafeGuard File Encryption for Mac|
Before working with removable devices, make sure you have been assigned a policy and key that allow you to encrypt files on removable media.
To be able to exchange and modify data on removable devices between two parties, both parties must have the corresponding policy and key assigned. No personal keys can be used. For the exchange between Windows and Mac OS X clients, the device must be formatted using FAT32. Since the file format cannot be displayed in the Finder, you have to use Disk Utility to check the file system. For the Windows client, a data exchange policy is necessary. The media passphrase functionality is only available for Windows. From a Mac OS X client, the data can be accessed only if corresponding policies of type File Encryption are defined.
