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 writing speed of my StoreJet extremely slow when the reading speed is normal? Why does the disk failed to be lock/unlock when employing Elite's "disk lock" function? What should I do if I receive an "Access is Denied" message when trying to open a drive or a folder?
