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 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? How do I use the new StoreJet on my Mac?
