You do not say what exact macbook air is this —the year is important here

what exact macOS are you currently running on your neglected mackbook air—this is important as well

How did you login to your account?

If you have only one account on your Mac, then you are admin, this is the same as your user psswd.

This is how you log into your Mac when you boot it up— with your username and password.

What is the issue beyond this...(?)

AppleID and psswd you needed to log into these forums, this is the same AppleID/psswd to download from the Apple Store.

What happens if you go through >System Preferences>Software update
