EOS-1D X MkII - CFast Card Not Being Recognized

[bwalley]

I have a CFast card reader, Imac pro with Sonoma 14.3.1 OS and it does not recognize the card, even if in the camera.

Yes it is a 1dx MKII

Dual Card reader, I record .jpeg to the CF card, RAW to the CFast card, the reader is a multiple card reader, the CF cards are reading fine, the CFast is not, I can't even download or see the RAW files on the CFast card when the camera is hooked up to the computer.

I have an iMac Pro and recently upgraded the OS to Sonoma.

I looked for updated drivers for the 1Dx MKII, but can not find any.

There are no drivers needed.

I am away from camera nd computer, so I am guessing about this: Which card do you have designated as the one the camera reads for the image review display. I think that might be the one that is also directed to the data out port.
