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 Transcend include the Proposition 65 warning? Why is it that my hard disk can only be allocated to 2TB, and the remaining capacity is displayed as "Unallocated" ? Can I use the Transcend external HDD / SSD / high-speed USB on my PS4 or Xbox?
