Has anyone run into this problem with their installation? I can live without the extFS capability (mostly there as a backup in case on of my Linux servers has an issue and I need to access a physical file systems), but I regularly use the NTFS capabilities provided by their read/write driver so this is kind of a show-stopper for me at the moment. I wouldn't think these would be particularly uncommon to run into (at least the NTFS package, it continues to be fairly popular), so it surprises me that I haven't run across any reported issues. What I seem to have found through step-by-step modifications is some form of kernel extension conflict between SoftRAID and Paragon Software's NTFS for Mac and extFS for Mac file system packages. My hardware is fine, I had been using an earlier Accelsior E2 card in the exact same slot with no problems. I've finally gotten to the point where I've torn down the system configuration to base install and removed any other PCI cards besides the GPU. At best the system is very unstable when the card is installed, at worst it refuses to boot, simply rebooting constantly in the middle of the startup. I've been working with OWC Tech Support for a few months now trying to get an Accelsior 4m2 setup in a MacPro 5,1 running Mojave.
