It doesn’t matter unless you’ve enabled root login. “sudo” is a better tool for privileged access anyway.

From what I've read, the issue occurs even if you have not explicitly enabled root login. That's part of the problem - the OS is seemingly enabling the root account to check the password and that's why when you try the login with a blank password you have to try it twice.

I’ll take your word for it. The two Macs I could access before I applied the fix have root passwords assigned so I can’t try it.
