I’m not sure what OS you are running. Try downloading the latest AJA desktop video driver software.

https://www.aja.com/products/io-4k-plus#support , 17.1.3 ,

The instructions I posted above were to correct a faulty software not recognizing the device.

I downgraded after that to Catalina for a more stable system. (Intel macpro cheesegrater.) haven’t upgraded since.

I upgraded to Big Sur and encountered the same problem. these two documents helped solve the issue.

upon booting I now have a small issue of not seeing the device, so I use Terminal to do this:

“After restarting, if the system fails to load the AJA driver:<br role=”presentation”>○Open the Terminal application.<br role=”presentation”>○Type in “sudo touch /Library/Extensions” into the Terminal window … then press Enter or Return.<br role=”presentation”>○When prompted, enter the password for the administrator account.”
