If you want to use Backup Plus Desktop exclusively with Mac computers, it is recommended that you use the format native to the Mac operating system, HFS+ (journaled).įor further information on hard drive file systems and instructions for formatting hard drives, review the section below. For details and instructions, see our dedicated support page for the Paragon driver for Mac. If you want to connect Backup Plus Desktop to a Mac as well as a Windows PC, you can install special software that allows Macs to read and write files to NTFS hard drives similar to Windows PCs. However, NTFS is not fully compatible with Mac computers. Therfore, you can connect Backup Plus Desktop to a Windows PC without formatting the hard drive. Your Backup Plus Desktop is formatted as NTFS for compatibility with Windows out of the box.
