We already wrote about how to protect your Mac at work in a public place - with the help of automatic screen lock. This is useful when working in a cafe at the university, in the office - if you move away from the MacBook, then nobody will be able to use it. But there is still one problem - at the bottom of the lock screen always hang three buttons that transform Mac in sleep mode, reboots or turns it off. And it turns out that you can restart the computer, anyone, and this greatly facilitates the work of the attacker. Fortunately, the Display of the lock screen can be turned off.
I will explain what is necessary to disable the buttons for each account separately. For example, if the Mac uses a few people, you as an administrator can not reboot from the lock screen. Here's how it's done.
- Open the "System Preferences" and select "Users and Groups"
- Click the lock icon at the bottom and enter the administrator password
- Open the menu "Login Options"
- In this menu, uncheck the item "Show button Sleep, Reboot, and Shut"
Do this for each account and no one will be able to restart or shut down your computer while you are away to buy a coffee.
