If you plan on using your USB on both Windows and macOS devices, the preferred format is ExFAT. Different File System Formats Available in Disk Utility ExFAT Let’s look at how to format your thumb drive for a Mac. Unless it’s specifically designed to work on a macOS, you'll need to reformat the flash drive.

It’s because most computers run on Windows and most thumb drives ship with formats that favor a Windows environment. Tuxera (who develop one of the commercial NTFS drivers for Mac OS X) have a list of free NTFS drivers that are developed from the same NTFS-3G source used by Linux to read NTFS drives.Have you ever tried to use a USB drive on your Mac only to realize you couldn’t write any files to it? For a while I've been using but as far as I can tell it hasn't been updated since December 2008. I'd love for someone to tell me differently. There are a few third-party products that allow Mac OS X to read NTFS formatted drives but as far as I'm aware the free ones aren't as well maintained as the commercial ones.

Mac OS X has had support for reading NTFS formatted disk for a few versions, but still doesn't have write support.

The default GUID partitioning scheme won't be recognised by 32-bit Windows XP and earlier Windows operating systems and Mac OS X versions earlier than 10.4. FAT32 (called MS-DOS (FAT) by Disk Utility a filesystem originally released in 1977 and updated a few times since, lastly in 1996) really is the only cross platform filesystem that is going to work fully out of the box with Windows and Mac OS X.īe careful though, if you are using Disk Utility to format the drive, you should make sure to choose the Master Boot Record partitioning scheme (hit the 'Options.' button below the 'Partition Layout' control on the Partition pane).
