How to Set Up a Hot Corner to Lock Your Screen Manually Next, set up a Hot Corner so you can quickly activate the screen saver when you leave your computer. From the Apple menu, choose System Preferences. Click Desktop & Screen Saver. Click Screen Saver, and then click Hot Corners. The OP said iCloud lock NOT activation lock. ICloud lock can be bypassed on a Macbook using an eprom device. I won't post videos but if you are a thief you already know. Lock Screen doesn't play nice with sidecar. The iPad doesn't lock and simply becomes available. The ugly part was, that it takes a while before the iPad comes out of sidecar mode, so you do not see it right away, and you are gone from your Mac the moment it falls back into unlocked iPad mode.
Apple M1 chip.
A shared architecture for security.
The Apple M1 chip with built-in Secure Enclave brings the same powerful security capabilities of iPhone to Mac — protecting your login password, automatically encrypting your data, and powering file-level encryption so you stay safe. And the Apple M1 chip keeps macOS secure while it's running, just as iOS has protected iPhone for years.
Apple helps you keep your Mac secure with software updates.
The best way to keep your Mac secure is to run the latest software. When new updates are available, macOS sends you a notification — or you can opt in to have updates installed automatically when your Mac is not in use. macOS checks for new updates every day and starts applying them in the background, so it's easier and faster than ever to always have the latest and safest version.
Protection starts at the core.
The technically sophisticated runtime protections in macOS work at the very core of your Mac to keep your system safe from malware. This starts with state-of-the-art antivirus software built in to block and remove malware. Technologies like XD (execute disable), ASLR (address space layout randomization), and SIP (system integrity protection) make it difficult for malware to do harm, and they ensure that processes with root permission cannot change critical system files.
Download apps safely from the Mac App Store. And the internet.
Now apps from both the App Store and the internet can be installed worry-free. App Review makes sure each app in the App Store is reviewed before it's accepted. Gatekeeper on your Mac ensures that all apps from the internet have already been checked by Apple for known malicious code — before you run them the first time. If there's ever a problem with an app, Apple can quickly stop new installations and even block the app from launching again.
Stay in control of what data apps can access.
Apps need your permission to access files in your Documents, Downloads, and Desktop folders as well as in iCloud Drive and external volumes. And you'll be prompted before any app can access the camera or mic, capture keyboard activity, or take a photo or video of your screen.
FileVault 2 encrypts your data.
With FileVault 2, your data is safe and secure — even if your Mac falls into the wrong hands. FileVault 2 encrypts the entire drive on your Mac, protecting your data with XTS-AES 128 encryption. Mac computers built on the Apple M1 chip take data protection even further by using dedicated hardware to protect your login password and enabling file-level encryption, which developers can take advantage of — just as on iPhone.
Designed to protect your privacy.
Online privacy isn't just something you should hope for — it's something you should expect. That's why Safari comes with powerful privacy protection technology built in, including Intelligent Tracking Prevention that identifies trackers and helps prevent them from profiling or following you across the web. A new weekly Privacy Report on your start page shows how Safari protects you as you browse over time. Or click the Privacy Report button in your Safari toolbar for an instant snapshot of the cross-site trackers Safari is actively preventing on that web page.
Automatic protections from intruders.
Safari uses iCloud Keychain to securely store your passwords across all your devices. If it ever detects a security concern, Password Monitoring will alert you. Safari also prevents suspicious websites from loading and warns you if they're detected. And because it runs web pages in separate processes, any harmful code is confined to a single browser tab and can't crash the whole browser or access your data.
Find your missing Mac with Find My.
The Find My app can help you locate a missing Mac — even if it's offline or sleeping — by sending out Bluetooth signals that can be detected by nearby Apple devices. These devices then relay the detected location of your Mac to iCloud so you can locate it. It's all anonymous and encrypted end-to-end so no one — including Apple — knows the identity of any reporting device or the location of your Mac. And it all happens silently using tiny bits of data that piggyback on existing network traffic. So there's no need to worry about your battery life, your data usage, or your privacy being compromised.

Keep your Mac safe.
Even if it's in the wrong hands.
All Mac systems built on the Apple M1 chip or with the Apple T2 Security Chip support Activation Lock, just like your iPhone or iPad. So if your Mac is ever misplaced or lost, the only person who can erase and reactivate it is you.
macOS Security
iMac is a classic representative of an all-in-one computer, whose user from the box gets everything they need to get started right away. Over the years, the iMac market has undergone significant changes; the periphery that came with it also changed, but regardless of the model year, model or equipment, users of any iMac get a branded mouse and keyboard from Apple.
Of course, iMac can work with any third-party peripherals, but it is the branded input devices that allow you to realize the full potential of macOS.
Today we will consider the case when the Num Lock section does not work, when the Mac keyboard is connected, and also I will tell you about how to solve them.
Separately, I want to note that the keyboard in right bar may not work for many, including hardware reasons. If the problem is in the motherboard or, for example, the Bluetooth module, then it may require more complex repair of the iMac than simply restoring the settings or 'resetting the pair', but any problem can be solved, everything in order.
Remnants of the Past Era
On some laptops, including older Macs, Apple keyboard Number Lock had a different function. There he turned part of the keyboard into a pseudo-trackpad. The buttons U, I, O, P, J, K, l, semicolon, M, period and slash (slash) were assigned to this role. Num Lock was activated on such computers by pressing the F6 button. Apple stopped supporting Num Lock on the F6 in 2008.

Where is the Num Lock key?
If you look at your keyboard, then on Nam Lok Pade, above the number '7' there is a 'Clear' key, this is an analogue of the Num Lokc key.
What to do if Num Lock Does not Work?
Apple, in fairness, has not forgotten about this feature since the time of IBM at all. Now it is available as Accessibility settings called Control Keys (called up by pressing Option (Alt) + Command (⌘) + F5):
- It can also be activated via the 'System Preferences' -> 'Accessibility' -> 'Mouse & Trackpad' path;
- Click on 'Enable Mouse Keys';
- As a result, the numbers on the keyboard with a digital unit become 'arrows'. To 'click' with such a 'mouse', press the number 5 to press and hold, press 0, to release, press the point.

The Num Lock key was the product of an 'past' era, when mechanical and numeric keys peacefully coexisted with each other. On some IBM computers there were no arrow keys, but there was a separate digital block for quick input of numbers. Over time, IBM figured out how to combine these two functions. The Num Lock button blocked a set of numbers and turned the 'digital' keys into 'arrows'. With their help, it was possible to move the cursor on the screens of computers that did not know the mouse yet.
