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 Does my StoreJet support both Windows and Mac OS? Why are there files in my new StoreJet (external-HDD)? What are these folders/files for? If the files you hope to back up contain those that are not allowed to be backed up, a warning message will pop up from Elite and the backup task will be interrupted.
