Thank you but I really get confused which dubious terminology:
Q1. When you write “computer password” do you mean the password of the “Admin account”?
Q2. IDEM for the article’s terminology: when the article indicates “Mac login password” do they mean “computer password” or the password of the “Admin account”?
Q3. I never heard the computer itself should have a password, or do I misunderstand?
Q4. And if it is the mac mini itself which should have a password, how to install it?
If I need to change the password of any of my 3 users, I can simply do this via “Users & Groups“ in “System Setting”, so I’m afraid the computer itself should have a password.
IN CASE IT HELPS: I have a secure APPLE ID and PASSWORD (how else could I have entered an issue in this Community?) and the macOS Ventura was installed by a professional team.
The Mac Mini (M2) was new April 2023. The old macOS was not (sept. 2011), as well as all applications and data: there were coming from El Capitan (on an old mac mini).
Thanks for clarifying.
