we have macbook its failing 802.1x and then passing MAB , we checked certificates are good, and he can connect to meraki which only difference is using wpa 2 while cisco ap using wpa2+wpa3 . then i saw many users were complaining with macbook to wpa 3 and thinking maybe this is the problem
Then you definitely need debugs on WLC and client at the same time and ideally OTA packet capture to understand why/where it's going wrong. Then you know whether it's an Apple or Cisco problem and raise it with the respective vendor. Do you have APSP installed on 17.9.4? (refer TAC recommended link below)
