For some odd reason Mac systems do not mount ntfs as read/write. It will only mount the disk as read only by default. Which is good in some cases but what if you want to write to a external drive for remote use. This makes it very hard for the average user to use Mac in conjunction with other systems.
I used the below method which may not be conventional but it seem to work. I check several online forums which said to add a entry into “fstab” then remount the drive. The drive was still mounting as RO.
The below command will show you all devices connected to the usb bus . This is one way to grab the uuid to mount the drive via terminal
if you want to only grab the name of the disk use grep like so
system_profiler SPUSBDataType | grep BSD
Mass-MacBook-Pro:~ mas$ system_profiler SPUSBDataType | grep BSD
BSD Name: disk1
BSD Name: disk1s1
Mass-MacBook-Pro:~ mas$ diskutil info /dev/disk1s1 | grep -i uuid
Volume UUID: 6EC60DFC-E887-43FC-BF91-0DF8B1565759696
>Another way is if you know the device name
diskutil info /dev/disk* — replacing * with the actual name of the device
If you plug the device in already and want to remount with read/write. First umount the existing disk. Run df to check for the existing mount point then run sudo umount “mount point path”
Next create a virtual directory to use for the rw mount point. Also add an entry in the Fstab file as follows.
And create an entry in “Fstab” sudo nano /etc/fstab
UUID=6EC60DFC-E887-43FC-BF91-0DF8B1565759696 external ntfs rw,auto,nobrowse 0 1
Now that you have the uuid and virtual directory created. run the below command to mount it
diskutil mount -mountPoint /Volumes/external 6EC60DFC-E887-43FC-BF91-0DF8B1565759696
Replacing the numbers at the end with your device volume uuid.
