Wi-Fi drivers not detected means that the device(hardware) is not recognizable. It might be a hardware incompatibility issue.
Kindly try connecting to LAN/wired connection if available.
We have the new version of ISO released, you may test this if it is not the one which you have downloaded already.
Hi Keerthy. I tested the new ISO with Macbook Pro 2018 and 2019 and the keyboard and touchpad were still not supported. I am afraid it will be the same for the wifi card. Though the new ISO supports wider range of computers, it did not bring better support for Apple computers, I am afraid
You are experiencing the known issues and you did it right.
You removed security and enabled USB booting by Apple startup utility and you booted.
Your internal keyboard, touchpad, and wifi were not recognized
You can use this computer still but all your devices have to be connected externally using USB adapters and hubs. You need to have an external keyboard, mouse, network card, camera, and monitor. Hopefully, the microphone will work from the camera.
The only issue may be the USB adapters. If it is a multiport adapter running over Thunderbold protocol, it will not be fully supported and reliable for the exam. You need to have simple, ordinary USBc to USBa adapters and a pure USB hub. It is doable, but it is hard as you need to have all those adapters. I am using Macs also daily for 30+ years (no kidding, started with Powerbook 145c and Apple Macintosh LC3, but I would grab and use some older Lenovo or Dell laptop to take the exam.
The system requirements table describes the conditions for using external keyboards and

I do not know if there is a way to make an exception under special circumstances, However, you could write an email to firstname.lastname@example.org, to explain and the team will respond accordingly.
