install issues with macOS Ventura - asking for login repeatedly
I've downloaded MacOS Ventura on my Macbook Pro, but every time I try to install it, I get asked for my admin password, enter it correctly, and then select 'continue' - and I then get asked for password again. I'm stuck in a loop and can't install it!
The password is correct and I am definitely an admin (I double checked).
Any hints, or anyone find a way to resolve this?
Thanks
