I am setting up my new Mac and have forgotten exactly how things work... When my computer goes to sleep, I would like it to be locked. Also, when I do Ctrl + Shift + Eject I would like it to be locked. In the past I had issues getting this to work because you have to set the security features and Sleep and Screen Saver a certain way, and I forget what that combination is. Can someone help me sort this all out? Thanks. --- Post Merged, Sep 29, 2017 --- Oops, I just noticed Apple changed the settings from Mountain Lion to Sierra! Anyway, I am wondering... 1.) Does macOS truly lock your computer on either "sleep" or "screen saver" as the check box says? 2.) On Sierra, how do you choose a time to "Sleep"? 3.) How does "Turn off display" relate to "Sleep"? 4.) Do I even need a screen saver if I want to lock my computer?
