If you need access to your drive, there is commercial alternatives such as Paragon NTFS for Mac, or Tuxera NTFS for Mac.
I don't have much experience with either, but I believe them to be acceptable solutions.
If however, you feel in the experimental mood, there is unofficial NTFS support in macOS. However, no guarantee is provided.
In the recent macOS, this command should work:
diskutil mount disk1s1Where disk1s1 is the disk and partition number from diskutil list.
The volume will mount in read-only.
For the write access support, read: recommendations for reading and writing NTFS from macOS.
1You don't need external program to mount NTFS volume, follow these steps to mount NTFS external disk on macOS. This is tested and working on macOS Mojave-
sudo mkdir /Volumes/MyNTFS
sudo mount -t ntfs -o rw <Disk Identifier> /Volumes/MyNTFSTo get disk identifier, you can run diskutil list. For example, if below is the output-
/dev/disk2 (external, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *2.0 TB disk2 1: Microsoft Basic Data MyNTFS 2.0 TB disk2s1Then you can run following command to mount-
sudo mount -t ntfs -o rw /dev/disk2 /Volumes/MyNTFS It is NTFS, you cannot mount it. It must be Mac OS Journaled or FAT32.
4You can mount any NTFS disk, natively. You simply can't write to it without additional 3rd party software. If you can't see the drive at all, or it won't mount, the drive is most likely beginning to fail/failing/failed.
For those who are already using ntfs for mac by Paragon, and have faced the famous "Unable to mount" error,
try executing -
sudo kextunload /Library/Extensions/ufsd_NTFS.kext // unloads driver
sudo kextload /Library/Extensions/ufsd_NTFS.kext // reloads itThis is what worked for me.
However, if the issue persits, here's an article that might help -
