None of the steps I've read about bringing up my Pegasus2 R4 have worked on this Mac Pro running Big Sur 11.2.2. Each time it crashes and reboots the OS when I turn on the drive array.
Setting up the Secure boot sequence prior to installing the 6.2.16 driver to have access/permissions or changing the csrutil to disable for the boot sequence mentioned recently have not worked. Only once, the first time, did I see the message in Security and Privacy, and when I did, I enabled it. I also tried the terminal command to load it but only the prior version loads and still causes tjhe crash/reboot. The instructions in the downloaded PDF with the driver is inaccurate. There is no Reduced Security Option in the Startup Security Utility nor any mention of kernel extensions.
Software Extensions does list it, along with the previous version (6.2.13) but 6.12.16 never loads.
Any help would be great. This is a terrible situation.
