2.5. Please confirm that the version is 4.23.6.
2.6. Congratulations on the successful installation of the driver and the Thunderbolt3 device can be used.

What if you have gone through the install but your kextstat shows you an older version of the driver? (4.13.?)
How do you fix this? Is there a way to force the old driver to uninstall?

Hi!
It does not need to be updated to the latest driver, the 4.13.x version of the driver can be used normally.

Corrected the wrong version number.

So the original post with driver version 4.23.1 was incorrect and the proper one is 4.13.2 ? Please confirm. Thank you.

Yes, version 4.13.2 is suitable for MAC OS 11.4 or earlier.

Hello,

I have followed all the steps correctly, but the D8 does not recognize the disks.

There was a time when it did recognize them, I do not remember exactly which version of macOS Big Sur but when I installed 11.6 it did not recognize them again. So I had to downgrade to a version below 11.4

I attach the screenshots.
