I recently upgraded my Mac OS to Big Sur 11.5.2 and can no longer see/access my RAS. I have unloaded and reloaded the HighPointRR driver multiple times per the your past instructions. Upon loading the driver, I get the message saying the driver was successfully loaded, but can't seem to upload the driver such that the system indicates that it's loaded. Please see photos.

Please advise. Thanks.

what's your model number please?

Thunderbolt 3 D5 with five 8Tb Seagate Iron Wolf drives.

please refer to this instruction viewtopic.php?f=66&t=1106&hilit=big+sur

Hmm. Unfortunately, when I go to disable security, I only have two choices - either to add a password for firmware protection or to remove firmware protection. I do not see all the other choices displayed for the T1 chip, such as security levels for secure boot or allowed boot media.

I am running v3.1(9) of the Startup Security Utility, so I don't know if I have a newer or older version of the software. My guess is that my problem is related to how these options are set up on my computer.

Any advice?

Thanks in advance.

Thank you. My D5 Thunderbolt 3 is now working. I reinstalled the MacOS, removed the old RAID drive, then used the latest driver you provided. Appreciate your help.
