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 the file not successfully backed up when I use Transend Elite for scheduled backup? Why can't I partition my SSD or external hard drive on macOS? Why is the storage capacity of my StoreJet (external-HDD) shown on the computer less than the volume written on the package?
