Oct 17, 2019 Getting around this limitation is very easy with the caffeinate command but it only works so long as you’re on the desktop. Once you lock the screen, macOS’ own sleep settings take over and the screen is put to sleep within a minute. Here’s how you can disable lock screen sleep on macOS.
The Rocket Yard is the place to be for tips and hints about security, but one simple security tip that many people forget about is just making sure that your Mac screen is locked if you’re away from the computer for even just a few minutes. By locking the screen, I mean that anyone walking up to the Mac is required to enter the correct password to use it. Doing this can keep someone from just walking up to your Mac and looking at (or copying) your private files while you’ve walked away for a restroom break or to grab another cup of coffee.
Feb 07, 2018 Note this specific Lock Screen feature is only available in the latest versions of Mac OS, including macOS Mojave, or High Sierra 10.13.x onward. If you’re on an earlier version of Mac OS system software, you’ll need to rely on other methods to initiate the lock screen on a Mac as described here, or if you have a MacBook Pro with Touch Bar.
In today’s Quick Tip, I’ll show you how the “old method” of enabling an instantaneous lock screen worked and how macOS 10.13 High Sierra makes it even easier to lock your Mac’s screen.
The Old Method With macOS 10.12 Sierra and earlier versions of the Mac operating system, enabling the lock screen ability required setup by the user. Here’s how it was done:
1) Launch System Preferences from the Dock or by selecting System Preferences from the Apple ( ) menu
2) Click on “Security and Privacy” and then select the General tab
3) Click the checkbox next to “Require password after sleep or screen saver begins”, and make sure that “immediately” or “5 seconds” is selected from the drop-down menu as the time interval before the password is required (see screenshot below):
(Click the checkbox next to “Require password” and select “immediately” or “5 seconds” as the time interval.)
Mac Lock Screen Time
4) Exit System Preferences
Now when you walk away from the Mac, you can use one of a few methods to lock the screen when you need to take a quick break.
Press Control – Shift – Eject on Macs that have an Eject key or an external keyboard
Press Control – Shift – Power on Macs that don’t have an Eject key, like MacBooks
Set up a “Hot Corner” on your screen for putting the display to sleep, which will also lock your screen. To do this:
1) Launch System Preferences, then select “Desktop and Screen Saver”
2) Click the Screen Saver tab
3) Click on the Hot Corners button (see screenshot below)
(The location of the “Hot Corners…” button on the Desktop & Screen Saver preference pane.)
4) Select one of the four corners of your screen to act as a hot corner for putting your display to sleep. In the example screenshot below, I selected the lower right corner and chose “Put Display to Sleep” as the action when the cursor enters that corner:
(Select an active screen corner, then select “Put Display to Sleep” from the pop-up menu.)
5) Click OK, then exit System Preferences
Now when you place the cursor in the active screen corner, the display goes to sleep. Any movement of the mouse or trackpad, or a press on the keyboard makes a login screen appear and requires the correct password to be entered before the Mac can be used.
Lock Screen For Mac Os X 10 12
The New Method in macOS High Sierra Apple added an official Lock Screen feature to macOS High Sierra, making the entire process of locking your screen a lot easier. It’s available either from the Apple ( ) menu or with a simple keyboard shortcut. From the Apple menu:
1) Select the Apple menu while in any application
2) Select “Lock Screen” to instantly lock the Mac screen (see screenshot below). A login screen is immediately displayed; Lock Screen doesn’t start your screen saver, nor does it log out of the active account or quit any applications.
(Select Lock Screen from the Apple menu to immediately require a password to use the Mac.)
Alternatively, the Command – Control – Q keyboard shortcut also activates Lock Screen.
Add a Lock Screen Message
If you’re around a lot of people with similar MacBooks, it can sometimes be difficult to know which computer belongs to what person. One quick way to immediately identify a Mac from the lock screen is to add a Lock Screen Message. Here’s how to do it:
OS X and Linux, this is a very hot topic today to discuss when the company or user wants to choose between OS X and Linux but things are not in black and white. In a business, world cost is the factor which affects the choice since keeping cost low to maximize the profit is the main concern. OS X is irrelevant in the server market, so people tend to develop in VM's, but on Linux, developing locally tends to go smoothly. However: You can run Linux in a VM on an OS X host, but the other way around you're going to have a rough time, if you get it working at all. Doing iOS development on anything other than OS X is a shitty experience. An error message popup! -On Windows- Uh, ok:/ -On Mac- Perhaps if i could upgrade to the newest Mac it wouldn't happen -On Linux- Let's see if someone has. https://dashboardnew523.weebly.com/os-x-vs-linux-for-development.html.
1) Launch System Preferences, and select the Security & Privacy pane by clicking on it Neooffice for mac os high sierra.

(Enter a message to appear on your Mac’s lock screen, then click OK.)
4) Click the lock button again to save the change and then close out of System Preferences
Lock Screen Mac Os X Time
Now when your Mac screen is locked, it not only displays the login screen but also your message (see screenshot below):

The Lock Screen message can help return a lost MacBook to you and also sort out the owner of one of a number of identical Mac laptops!
