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? Related Why does the device show that the format is not supported when using the ESD OTG function? Why is it that my hard disk can only be allocated to 2TB, and the remaining capacity is displayed as "Unallocated" ? How do I format my StoreJet?
