What are some functional differences between the Windows and the Mac versions of Transcend Elite? Category : Software / Firmware / Applications Note: 1. To have the external hard disk support both Windows and Mac operating systems, we recommend formatting the hard disk into FAT32 or exFAT format. 2. The disk lock/unlock function for MacOS version is still under evaluation. Is the answer helpful?
