Q: How to log in automatically with a password?

Hey guys,

I bought a new Macbook this September, and I had a simple password.

Now I want to log in automatically without typing my password.

I have tried to reset my password to blank, but it didn't work.

My old Mac (not updated) doesn't require a password to log in and can log in automatically.

So is this a problem if you updated the Mac to the latest version?

Thank you!!!
