Password does not work when try first software update to mac OS Sonoma 14.2.1
This is a new iMac (2023) with OS Sonoma 14.1. I have had it a week.
As I try to install the software update, I enter my password, and that does not work.
I have tried entering my startup password, my apple ID password, and my old password. None are working.
What do I need to do?
Thanks for any help!
iMac (M3, 2023)
