I initially installed the trial version of Paragon NTFS on two of my MBPs before learning that I can get a free version because I have WD My Books. So I uninstalled the trial versions and installed the free WD versions. Unfortunately, it seems that this broke Paragon NTFS because I still couldn’t write to NTFS drives. I was able to resolve the issue on MBP by using a paid activation key but I’d really like to get this working using the free WD version so I can get a refund from Paragon. Any advice is appreciated!
