Do update me any time, especially if you have a problem.
Thanks This is the easiest directions I have read. As to you first question yes I have a bootable USB drive. As for this quote "
The next screen you see will display Bootable Sources.
Your USB drive should be one of them, if it is select it and allow the Mac to boot up.
I'll send you this now just to let you know I'm on the case, okay?
Please reply an I'll continue"
So it is at this point that I previous did not stop the boot up. It is at the point where it sounds like I should be stopping it after the initial boot and go into disk utility where I will wipe Aura Pro X2 Media. At earlier attempts I bypassed this and continued on to what I was expected to be an over- write upgrade. BTW I used that process on 2015 Mac Pro. successfully and therefore I expected the same on the 2013 Mac Air. But it froze 3 times in the same place
Now my pathway is it choose the below direction erasing and formatting. And I expect it will fall into place.
Choose Aura Pro X2 Media and click Erase.
Now you have a few tasks; you need to name it Macintosh HD
you need to format it APFS
and you need to Map it GUID
This is falling into place.
I understand the directions you made for me to continue the process and use time machine. I have 2 for this Mac. I think I'll choose the one with a much shorter volume. The Long volume goes back to 2018 and I just do not need to go back that far.
**Thanks** for everything and I will follow up.
Do update me any time, especially if you have a problem.
I will re-read this a couple times and maybe even do a copy and paste and print it so I can underline a few important places and I can also check some thing after they have been completed. It's not that complicated but there is a method to the madness. The Xs and Os have to be in place.
Thumbs up! Rod.
