Is there a similarly fast alternative to Crtl + Shift + Eject for new Macbook that lack eject keys?

Solution 1:

I'm using a MacBook Air 2012 with Mountain Lion, and the new keyboard shortcut is:

Control+Shift+Power

Solution 2:

I just found that I could lock my screen using the following shortcut:

Control ⌃+Shift ⇧+Power ⌽

Require password immediately after sleep or screen saver begins should be checked in the Security & Privacy in System Preferences panel if you want to ensure a slept screen is also securely locked.

Solution 3:

If you just need to lock the screen, you can use Control ⌃ + Command ⌘ + Q available since High Sierra.

Solution 4:

The easiest way to lock your computer is to set require password immediately and turn off the display with the following key combination: control + shift + power I find this super helpful and a great replacement for ctrl + shift + delete in Windows.

Solution 5:

There's a writeup here about using Automator to assign the keyboard shortcut of your choice to lock the screen.
