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 is my new external hard drive not working on my computer? Can I use the Transcend external HDD / SSD / high-speed USB on my PS4 or Xbox? Why is it that my hard disk can only be allocated to 2TB, and the remaining capacity is displayed as "Unallocated" ?
