There are a number of different ways to lock or sleep your screen in macOS. Before we show them to you, however, it’s important to make the distinction between locking your screen and just putting it to sleep.

Hi, is there a way to emulate the function keys F1-F12 in remote desktop? I'm running a program on my remote computer (win xp) that uses F9 as a shortcut, however when I press F9 expose still activates. Are there any keypresses that i can assign to emulate the F9 key? Caps lock on = fn locked (use function keys). Caps lock off = fn unlock (use media keys). I found a couple of topics around this problem, but their solutions didn't help me: Checking / unchecking the option 'Use fn keys as standard' in the keyboard preference panel is what I want to achieve when pressing /unpressing the caps lock key. Mar 19, 2020 Change the default function key behavior. If you want to change the top row of keys to work as standard function keys without holding the Fn key, follow these steps: Choose Apple menu System Preferences. Select 'Use F1, F2, etc. Keys as standard function keys'. Fn-left arrow (or right arrow). Walking away from your Mac? Tap this shortcut to immediately lock your machine. Touch Bar tip No. If you use a MacBook Pro with the Touch Bar, you can press.

If you lock your Mac you’ll put it to sleep and need to type in your login password on your Mac’s lock screen (or unlock it with TouchID on a MacBook Pro with Touch Bar, or with an Apple Watch). If you put it to sleep, you won’t necessarily lock it. In order to lock your screen, you need to set up the password in System Preferences. Here’s how to do that.

How to set up a password to lock the screen

1. Launch System Preferences either by clicking on its icon in the Dock or by choosing it from the Apple menu.
2. Click on the Security & Privacy pane.
3. Choose the General tab and check the option that starts ‘Require password…’
4. Choose an option from the dropdown menu.

Now, whenever your Mac goes to sleep or a screensaver starts, it will lock and you’ll have to authenticate with your user password, Apple Watch or TouchID to gain access.

How to lock your Mac

If you have a MacBook, a MacBook Air or a MacBook Pro, the quickest and easiest way to lock your Mac is just to shut the lid. When you do that, the Mac goes to sleep and when you open it again you’ll need to unlock it.

However, there are occasions when you’ll want to prevent anyone from seeing the screen without actually closing it. And, in any case, if you have an iMac, Mac mini or Mac Pro, it’s not an option. Here are some other ways you can lock your Mac’s display.

1. Use Apple menu

Go to the Apple menu and choose Sleep. This will display the login screen for your account and won’t unlock with a password (unless you’re wearing an Apple Watch when you do it and then it will lock and unlock immediately)

Tip: If you want your Mac to remain locked even when you’re close by and you have an Apple Watch, go to System Preferences>Security & Privacy>General and uncheck the Allow your Apple Watch to unlock your Mac option.

2. Use shortcuts

Lock Macbook Pro Keyboard

If you’re using a Mac that’s running macOS Catalina, go to the Apple menu and choose Lock Screen or press Command+Control+Q. This will lock your Mac and return you to the Login screen.

For older versions of the operating system, press Control+Shift+Power button (or Control+Shift+Eject if your Mac has an optical drive). It will lock the screen.

You can also use a keyboard shortcut to put your Mac to sleep. Press Command+Option+Power (or Eject). This works in a similar way to the previous one, but rather than just lock your Mac it powers down the hard drive, puts the CPU into low power mode and stops background tasks in order to save energy.

3. Set up a hot corner

Hot corners allow you to drag to the mouse pointer to one of the four corners of the screen to initiate an action – you can use one as a sleep shortcut on your Mac. To set it up:

1. Launch System Preferences.
2. Choose the Desktop & Screen Saver pane.
3. Click the Hot Corners button at the bottom right of the window.
4. In the drop down window, choose a corner.
5. Click on the menu and choose either Start Screen Saver or Put Display to Sleep.

4. Use fast user switching

Fast user switching allows you to quickly log into another user account on your Mac. But you can also use it to return to the log in window, which locks your Mac. Got to System Preferences>Users & Groups and click the padlock, then type in your password. Click Login Options and check the box next to ‘Show fast user switch menu as.’ You can also choose whether to show the menu as your full name, the account name or an icon.

To lock your Mac, click the fast user switching menu at the right of the menu bar and choose Login Window…

5. Add Keychain Access to the menu bar

This option was removed in macOS Mojave but works on versions before High Sierra:

1. Go to Finder.
2. Choose Applications > Utilities.
3. Launch Keychain Access.
4. Click in the Keychain Access menu and select Preferences.
5. Check the box next to Show keychain status in menu bar.
6. You’ll see a lock in the Finder menu bar. Click it and choose Lock Screen to lock your Mac.

As you can see, putting your Mac to sleep or locking it is very easy. There are lots of different ways to do it, although some are dependent on the version of macOS you’re using.
