I am about to take the exam. I am using 2017 Mac Pro, and try to use it for the test. I have downloaded the remote test image and install on USB, but after i loaded the Fedra OS to memory. My laptop just couldn't connect to Wifi for whatever the reason is. I sit close to the wifi router but still not working. For some reason, it just couldn't connect to the Wifi unlike I am using the Apple OS now.
