Suggested March 2024 How To Use Lock Screen In Macos Big Sur, Catalina, Mojave, & High Sierra
Mac users have long been able to use various tricks to lock the screen of their computers, but with macOS Big Sur, Catalina, Mojave (and anything from High Sierra 10.13.x onward), a simpler and faster option is now available on the Mac with an official Lock Screen feature.
With the new Lock Screen feature, you can instantly lock down a Mac through a system-wide menu option, or with a keyboard shortcut. Once Lock Screen has been enabled, a proper user login and password must be entered before the Mac can be accessed again. This is an excellent privacy and security feature, and one that Mac users should familiarize themselves with if they frequently use their computers in a public setting, be it at work, school, home, or anywhere else they may want to password protect their computer to prevent unwanted access.
Note this specific Lock Screen feature is only available in the latest versions of Mac OS, including macOS Big Sur, Catalina, Mojave, or High Sierra 10.13.x or later. 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 you can set a dedicated screen lock button.How to Use Lock Screen in MacOS via Menu
You can enable the Lock Screen on Mac OS from anywhere via the Apple menu:
Pull down the Apple menu from any application
Choose “Lock Screen” to instantly lock the Mac screen and bring up the login window
Locking the screen is instantaneous, and the Mac will require a password to login and regain access.
Another option to enable the Lock Screen feature on the Mac is to use the keyboard shortcut…How to Enable Lock Screen in MacOS via Keyboard Shortcut
The default keyboard shortcut for the new MacOS Lock Screen option is Command + Control + Q, you can hit the keystroke at any time to lock down the Mac:
Hit Command + Control + Q to activate Lock Screen on the Mac
Once you hit the command sequence on the keyboard, the Mac screen will instantly lock out, thereby requiring a login to regain access.
For many users, using the keyboard shortcut for Lock Screen will be faster than the menu option, and it’s likely that the keystroke approach is the fastest way to initiate a screen lock procedure on any Mac.
Note that you can change the Lock Screen keyboard shortcut if you’re unhappy with Control + Command + Q for whatever reason by going to the Keyboard system preferences. If you find yourself accidentally quitting apps instead of locking the screen, you may wish to do that. Just be sure your new keystroke doesn’t conflict with anything else.
To reiterate, these dedicated Lock Screen keyboard shortcut and menu options are only available to the latest versions of macOS system software (10.13+), but that does not mean that users of prior Mac OS software releases are left in the dark or without similar options to quickly activate a password screen to lock down a Mac. In fact, all versions of Mac OS can enable a lock screen associated with the Mac Screen Saver feature as described here that can be activated by keystroke or by a mouse corner. Another option is to use an optional Screen Lock button on the Touch Bar of MacBook Pro if you have one of those Macs.
The primary difference between the new Lock Screen option in modern macOS releases versus the older lock screen trick available in earlier Mac OS releases is that the new variation is officially recognized as “Lock Screen” whereas earlier versions of Mac OS would indirectly go about enabling a lock screen by activating the screen saver with password protection. The end result is basically the same however, though the new variation won’t immediately enable a screen saver, whereas the screen saver based approach always immediately does.
By the way, if you’re using the Lock Screen feature for security and privacy reasons (and you should be if your Mac gets used in any work place, public location, school, or even many home environments) then you’ll also want to be certain you enable FileVault disk encryption on the Mac so that all data on the hard drive is encrypted, further protecting your personal data from prying eyes or potential privacy incursions.

If you’ve installed macOS Big Sur, you’re going to notice a lot of changes to the appearance of your Mac. And one such change is not only to the appearance but function as well; it’s the Notification Center. The Notification Center on Mac now looks more like the one your iPhone and iPad.
You have a single column for Notifications and Today view, can see notifications grouped by app, and can show less, more, or clear notifications. You can also add widgets and select the size and act on items like replying to an email or snoozing a reminder.
Here, we’ll show you how to customize and use the improved Notification Center on your Mac (running Big Sur or later).Notification Center on Mac
Accessing the Notification Center
This opens the Notification Center in a single column view. You have your notifications at the top and Today widgets at the bottom.
If you don’t like the stacked view, you can change it. And the nice thing is, you can change it per app. So, maybe you want your News notifications stacked, but not your emails from Mail.
To changing the Notification Center grouping, follow these steps.
1) Open System Preferences using Apple icon in the menu bar or button in your Dock.
2) Select Notifications.
3) Choose the app on the left that you want to change.
Automatic: Grouped automatically when more than one notification is received.
By App: Grouped by app in a stack with the most recent notification at the top.
Off: Grouped by app but not stacked, also, with the most recent at the top of that list.
Tip: You can keep the Notifications Preferences window open while you make the change and then open the Notification Center to have a peek. This gives you a quick way to change it back if you don’t like it.
Acting on notifications
In some cases, you can take care of what you need to right inside the Notification Center. For instance, if you reply to a Slack message, you can do it without the app opening.

Viewing Today widgets
You can quickly rearrange your widgets by selecting dragging them where you want them. Just note that widgets stay at the bottom of the Notification Center.
Adding and editing widgets
On the left are the available widgets with a Search box at the top if you want a particular one. In the center are previews of the widgets with available sizes and on the right is how the widgets display in the Notification Center.
Drag it to the spot you want it in the Today widget area.
Finding more widgets
There currently isn’t a way to find more Notification Center widgets on the App Store from the widget editing screen. Those you see on the left or find with the Search are only for apps you have installed on your Mac. Hopefully Apple will add a link for widgets on the App Store down the road. But if you open the App Store on your Mac and search for “Notification Center widgets” you can find some others.
Any time you install a new app that offers a Notification Center widget, it should display as an option on the widget editing screen.Wrapping it up
The updated Notification Center on Big Sur make take some getting used to if you’re new to this layout, for instance, if you don’t already own an iOS device. But it gives a condensed, nice one-column view of both notifications and Today widgets at a glance.
Let us know your thoughts on the Notification Center on macOS Big Sur! Are you happy to see it look more like iOS or did you prefer it the way it was?

When testing out beta versions of macOS, I rarely install them on my main Mac volume containing the current version of macOS. Instead, I prefer to simply create a second volume dedicated to the beta. This option has been available since the release of macOS High Sierra, and makes it extremely easy to install multiple copies of macOS without having to deal with disk partitioning, sizing, etc.
By simply creating another APFS volume on the existing APFS container, you’ll have a dedicated spot for the macOS Big Sur beta to live. With this method, I can easily keep my production system separate from the beta, and just as easily switch between the current version of macOS and the beta version. In this brief video tutorial, I’ll show you how easy it is.
With all of that being said, I’ve updated two of my Macs, both containing additional APFS volumes for the Big Sur beta, to the latest version of macOS Catalina 10.15.6. These updates worked just as expected and I have encountered zero issues. Of course, your mileage may vary based on what Apple disclosed in its beta release notes.
Note: To use this tutorial your Mac must already be using an APFS-formatted startup disk. Available on macOS High Sierra or later.
Before starting any procedure involving a beta, it’s imperative that you back up your Mac. You can use Time Machine to keep your Mac backed up. This will allow you to restore your Mac in case anything goes wrong.
If you need help getting the macOS Big Sur beta, check out 9to5Mac‘s tutorial for acquiring the forthcoming public beta. For a hands-on look at the new features and changes in the next version of macOS, be sure to watch our Big Sur video walkthrough.How to install macOS Big Sur public beta on a second APFS volume
Step 1: Download the macOS Big Sur beta. This download can originate from Apple’s Developer Center, or via the forthcoming Big Sur public beta.Video: How to install macOS Big Sur beta on a separate APFS volume

Step 4: Close Disk Utility.
Step 7: Authenticate the helper tool to allow the installation to commence.
Step 8: Eventually the macOS Beta utility will request that you restart. Once you restart, the installation will continue.
Step 9: The installation will take a while to complete, so be patient. Once the installation is finished, you’ll be asked to configure macOS Big Sur.How to switch between the two Big Sur and Catalina volumes
Switching between each APFS volume is easy. You can either go to System Preferences → Startup Disk to choose a different volume to boot from, or simply hold the Option key on your keyboard while rebooting to select a different boot volume.
Select between Macintosh HD (Catalina) or Beta (Big Sur)9to5Mac’s Take
With APFS’ ability to automatically adjust volume size to fit your content, it’s much easier to create a separate space for beta versions to live when compared to traditional partitioning and allocation of disk space.
Of course, you can always install the macOS Big Sur beta on top of your existing Catalina installation; there’s nothing wrong with that method. But this early in the game I like to keep the two systems quarantined to their own separate volumes. This allows me to easily switch between Catalina and Big Sur at will, and any issues that I experience with the Big Sur beta won’t end up affecting my main Catalina machine.

The spotlight collection of lock screen images on Windows 10 and 11 is one of the best image collections currently available. It randomly rotates through a large collection of fantastic natural scenery and landscapes and has been designed for use on a range of different screen resolutions. Anyone who has used a Windows 10 device will be familiar with some of Spotlights popular images.
How do you set Spotlight lock screen images as Windows 11 desktop backgrounds?
To start using images from Spotlight as your desktop wallpaper, you’ll need to make sure you have the latest version of Windows 11 installed on your device. Once you have updated to the latest version, you’ll need to do the following.
First press the Windows Key + I to open Settings.
Next, change to the Personalise tab in the left-hand pane.
Here you will see a drop-down menu at the top of the page next to the Personalize your background heading with several different options. Select the Spotlight collection option and Windows 11 will update your desktop with images from the Spotlight collection.
As of writing the option is currently available to insiders in the following countries in Dev build 22518.
Australia, Canada, China, Finland, France, Germany, India, Italy, Japan, Korea, Norway, Spain, Sweden, the U.K, and the U.S. As usual, like other features, new features will be delivered first to Dev insiders for testing and further for feedback, after that to beta and release preview, and then after to public.

It has been a while since we’ve seen lock screen and welcome screen issues on Windows, however, it seems that we’ve come full circle. You may remember back when Windows 10 was first released these kinds of issues were quite common and were relatively easy to fix. This time around, on Windows 11, they appear as follows.
Occasionally when you turn on your computer it will boot to the login screen, then freezes, preventing you from entering your password/pin. Even if you have configured your Windows 11 computer to boot straight to Windows without a password, it may get stuck at the lock screen phase. Thankfully there are quite a few different troubleshooting steps you can run through to solve this problem so follow along as we get straight into them.
How do you fix Windows 11 stuck at the Lock Screen, Welcome Screen before login?
Before you start the more in-depth solutions shown below, make sure you have done the following:
A full virus/malware scan on your computer
Checked for any Windows 11 updates.
Updated your computer’s BIOS.
Once you have checked all of those, proceed.
Use the System Restore tool to revert back to an earlier time.
To revert back to an earlier system checkpoint do the following:
Open the Start menu and search Recovery. When the option appears select it.
When picking a Restore Point to use, I usually go back at least 2 weeks or to the last major update.
Run the SFC Command to fix and restore any issues.
This is standard procedure for any repair task on Windows. I’ve had to use this quite a few times over the years with a lot of success. Just be aware if you are using a custom theme (Deviant Art kinda stuff) This will require you to reinstall your theme again.
To start, press Windows Key + X and open Command Prompt (as administrator).
In the Command Prompt window type sfc /scannow, then press Enter. Now, wait for the process to finish. (it may take a while)
If your computer is in full working order, without any corrupt or missing system files, the scan will show the message: Windows Resource Protection did not find any integrity violations.
Note: If sfc doesn’t find any errors proceed to the next solution, skipping the 3 dot points below.
If there are problems the message will be: Windows Resource Protection found corrupt files but was unable to fix some of them. If this is the message you receive, continue with the next bullet point.
Boot your computer into safe mode. If you are running Windows 7 or older, restart your computer and continuously press F8. The Advanced boot will display when it boots. Select Safe Mode with Command prompt and press Enter. If you are using Windows 8 or 10 you will need to use a different method which can be found here: Advanced Startup options for Windows 8 and 10.
Once you are booted into Safe Mode, open Command Prompt as admin again and run the sfc /scannow command another time. This will repair corrupted Windows system files.
Once the commands are complete, Windows 11 shouldn’t have any more lock screen issues.
Run the DISM command to fix Windows 11 Lock Screen freezing.
If none of the above has worked so far, you can try running the DISM command to fix Windows 11 lock screen freezing.
Open Command Prompt (as administrator).
Type DISM /Online /Cleanup-Image /RestoreHealth into the window and press Enter.
Wait for it to run as it takes some time.
Once it’s finished Restart your computer.
Run the chkdsk Command to fix Windows 11 Lock Screen freezing.
The check disk command on Windows 11 will check for errors and automatically fix them. To run the tool copy and paste the following command into Command Prompt (as administrator).
chkdsk /f C:
Rollback to an earlier version of Windows 11. Uninstall Windows Update.
To go back to an older version of Windows 11 you’ll need to do the following. Sadly this can only be done within 10 days of the last update. If it has been more than 10 days, the Go back option will be greyed out.
From my experience using this tool over the years, it will generally take longer to roll back than it initially took to update in the first place. So make sure you don’t need to be using your computer for at least an hour, two at the longest.

How to use green screen in CapCut
Green screen can be used in two ways in CapCut. CapCut has its algorithm-powered background removal tool that can remove the green screen for you. Additionally, it also comes with a chroma key option where you can key out any color you wish. Follow one of the methods below that best fits your current needs and requirements.
Method #01: Use Background remover (Android only)
Sadly, background remover is unavailable for iOS users. If you wish to remove the green screen in CapCut on iOS, then you can use the next guide.
Download and install CapCut on your Android device using the link above. Once, installed, launch the app and tap on ‘+ New project’.
Now select your background clip from your local storage. If this is your first time using CapCut, then you will need to grant it the necessary storage permissions.
Tap on ‘Add’ once selected. You can also select multiple background clips.
The clip will now be added to your timeline. Trim the clip if needed and then deselect the clip. You will now get general menu options at the bottom of your screen. Tap on ‘Overlay’.
Tap on ‘+ Add overlay’.
Now select your green screen clip you wish to add from your gallery.
Tap on ‘Add’ in the bottom right corner of your screen.
Tap on ‘Remove background’ in the bottom right corner of your screen. Depending on your resolution and screen size, you might need to scroll to the right on the bottom of your screen.
CapCut will now automatically remove the green screen background from your clip. You can now proceed to edit your project as you wish.
And that’s it! You will now have keyed out the green screen in CapCut.
Method #02: Key out green screen (Android and iPhone/iPad)
The option to key out green screen is available for both iOS and Android users, and the layout for the app is same on both devices. Hence you can use the common guide below on both platforms.
Open CapCut and tap on ‘+ New Project’.
Tap and select your background clip from the local storage.
Tap on ‘Add’ in the bottom right corner once you are done.
The clip will now be added to your timeline. Tap on ‘Overlay’ at the bottom of your screen.
Now tap on ‘+ Add overlay’.
Select your green screen clip from your local storage and tap on ‘Add’ once selected.
The clip will now be overlayed on top of your background. Tap and resize the preview if needed. Once done, scroll the tools at the bottom to your right and tap on ‘Chroma Key’.
You will get a color picker in the preview at the top of your screen. Tap and hold on to the picker and move it around to select the desired color you wish to key out.
Once selected, tap on ‘Intensity’.
You will now get a slider to adjust the intensity of your color removal. Use the slider until you achieve the desired effect you had in mind.
Repeat the same step above for ‘Shadows’. Ideally, a mix of shadows and intensity will help you get the perfect green screen effect for your clip.
Once you are happy with the outcome, tap on the ‘check mark’ in the bottom right corner of your screen
You can now select the clip and reposition it according to the preview if needed.
Finalize your project by making other essential edits and export your project as you normally would. And that’s it! You will now have easily keyed out your green screen in CapCut.
Customize background removal: Tips
Sadly, CapCut only gives you limited control when it comes to keying out colors from your clips. You get access to the following sliders.
Intensity: This slider helps you adjust how intensely the color is removed from your clip. In practicality, this slider in turn helps you manage and dictate the edges of your subject when removing the color. This can be quite useful in certain textures like fur where you are dealing with tons of fibers and edges. Sadly, this doesn’t mean that the intensity slider offers you tons of control, rather you get access to a basic slider that doesn’t feature any tools to fine-tune the edges. But something is always better than nothing.
Shadows: The Shadows slider allows you to apply artificial shadows to the edges of your green screen subject to help enhance their outline without having it look out of place. This is quite a useful feature in case there is a lot of noise in the background or if the subject’s lighting is different from the lighting used in the background. You can use the shadow slider depending on your current screen to increase or decrease the number of shadows at the edges.
