Windows uses the NTFS hard drive format for its hard drives. Mac OS X can read files on NTFS hard drives, but it can't write files to them, which is a glaring omission. Attempting to drag a file into an NTFS drive in Mac OS X will only result in your mouse cursor turning into an error sign. Since most Hackintoshes dual-boot Windows and Mac OS X, being unable to share files between hard drives can lead to problems with file management. Fortunately, you can enable NTFS writing on Mac OS X with relatively little trouble.
Read past the break for more. LAST UPDATED: December 10, 2013 (Mavericks support) NTFS-3G (Free). Is a Mac app that enables reading & writing to NTFS drives on Mac OS X Snow Leopard for free. You need to install the driver as well, for NTFS-3G to work. Once you've installed both NTFS-3G and Macfuse, you'll be able to write files to your Windows hard drives flawlessly.
Jun 27, 2017 Most Mac users will be better off formatting external drives with exFAT, ensuring they work well on both Windows and Mac OS X without any extra work. If you must write to an NTFS drive, one of the paid, third-party drivers will be the easiest option.
Unfortunately, development of the Macfuse driver has stopped, so there will likely never be any official support for newer versions of Mac OS X. In Mac OS X Lion, Mountain Lion, and Mavericks, you'll instead have to install the driver, a replacement for Macfuse (be sure to checkmark the 'MacFUSE Compatibility Layer' when running the OSXFuse installer). However, even with OSXFuse, NTFS-3G does not work fully in Lion, Mountain Lion, or Mavericks; you will still get mounting errors every time your computer boots. To fix these errors, you'll have to install this. These post-Snow Leopard compatibility issues affect all free NTFS enablers, including apps like. Paragon NTFS ($20).
NTFS-3G normally works pretty well on Lion, Mountain Lion, and Mavericks with OSXFuse, but there are paid options as well. For instance, is a simple $20 app that enables writing to NTFS drives on Mac OS X, with no hassle involved. This app and claim to offer better reading/writing performance than the standard NTFS-3G + Macfuse/OSXFuse setup, though I haven't verified this myself.
Tuxera costs $32 and essentially does the same thing as Paragon NTFS, which is why I recommend Paragon's app instead. Ending Notes Though both NTFS-3G and Paragon NTFS work flawlessly for dragging and dropping files into your Windows hard drives from Finder, they're not perfect solutions. Your Windows hard drives have to be remounted every time you reboot, so they're not always available the moment Mac OS X starts up; you have to wait for Disk Utility to mount them.
This can lead to issues with apps that try to access those drives at startup, e.g.
Sharing data between a Mac running macOS or OS X and PCs running Windows may not be that straightforward. By default, Macs can only read files from Windows-formatted external hard drives, but not write to them. This prevents you from saving, editing, copying, or deleting anything stored on your drives using your Mac. The reason behind this? The file system used by Macs (HFS+) is different than the file system used in Windows (NTFS). How to read NTFS files on a Mac There’s a real easy solution for this, however: your Mac just needs a driver. Tuxera NTFS for Mac is a full read-write NTFS driver that enables your Mac to read and write NTFS-formatted drives.
