Assuming no hardware issues, it is likely your ISO was corrupted. I would recommend re-downloading it and writing it into the USB stick again (preferably a new stick to rule out the problem with the old one).
If there are any suspicion that the ISO was/is corrupted, then there is a simple verification check: calculate the sha256sum (or using the older, deprecated md5sum as indicated in the getting ready guide):
Look page 27:
How do I check the integrity of the remote exam live USB image I have
The MD5 checksum for the Live USB Image is: 0dd72ac558fc1afbf0c0e1fa4b366f10.
I have verified for you, at the time of writing the md5sum of the currently available iso found at "https://static.redhat.com/downloads/training-certification/rhrexboot.iso" (as indicated in the prep guide) is indeed: 0dd72ac558fc1afbf0c0e1fa4b366f10.
Hi , i have same proble with other collegue , not possible create BOOT FILE ,
I think the file was corrupted.
C:\Users\poliveira\Downloads>certutil.exe -hashfile c:\Users\poliveira\Downloads\rhrexboot.iso MD5

CertUtil: -hashfile command completed successfully.
The check sum not is euqal the document.

Hi, just wanted to check - can I use a headset for mic and audio?
The only other mic I have is built into the webcam, and it wasn't loud enough in the test.
Hi @tomcorcoran ,
Like @Gineesh said, all candidates are supposed to prepare their setup (the preparation guide says "2-3 days prior to your exam:").
Unfortunately in your case, that is a bit late and certainly stressful to do that a few hours before the exam...
I would suggest you try to work with the live support team, helping to prepare the Remote Exam, see the button at the end of page 1 of the preparation guide:
Regarding your system, "Mac Big Sur" only indicate the OS and not the hardware.
That OS is from end 2020, so fairly recent. Quite likely you have the hardware with the infamous T2 security chipset. Do read at the end of the preparation guide, there are some FAQ explaining about the issues with that type of hardware...
I hope the live support can help you. Unfortunately, based on the recent OS; you probably have a recent MAC hardware, which is quite likely to have the T2 chip, and therefore hardware limitations preventing you to run Linux on that device... So as an external observer, without knowing all the facts. I think your situation is not very promising.
PS: I'm saying as an exam candidate myself, for further tries, nobody wants/need the last minute stress of preparing the remote exam environment on the exam day. It's best to read the preparation guide attentively and follow the advice written there.
Possible I could get some assistance? I'm using a Mac - Big Sur
