Upgrading your Mac may seem cumbersome, but it's an integral part of online protection. Apple and app developers close vulnerabilities when they're found – and they're also adding helpful new features to macOS and your applications.
In addition to the usual security patches and app updates, Apple Mac users can enjoy brilliant new versions of macOS Year ̵
Installing macOS Updates
Apple releases a major new release of macOS every year, usually around October. Larger updates provide additional patches to fix bugs, fix security holes, and sometimes add new features and support for new products. These patches are simply called updates and recorded in the version number, where 10.14.3 is the third update to macOS 10.14.
These updates are making changes to the core operating system, the first-party apps such as Safari and Mail. and may include firmware updates for hardware and peripherals. You do not have to worry about installing the wrong device because Apple only provides updates that are relevant to your Mac.
If you are using macOS Mojave 10.14 or a later version of macOS, you can update your Mac by clicking on "System Preferences" in the Dock and then select "Software Update" in the displayed window. Or, click the Apple menu icon in the menu bar and choose "System Preferences."
You can also search for this option by pressing Command + Space and then entering "Software Update" in the displayed Spotlight window. 
Assuming you're connected to the Internet, your Mac looks for available system updates. Click "Update Now" to start the update process. Your Mac may need to be restarted before the process is complete.
If no Software Update option appears in the System Preferences window, you have macOS 10.13 or earlier installed. You will need to install OS updates through the Mac App Store.
Launch the App Store from the Dock and click the Updates tab. Once the window has been updated, all updates should be listed as "macOS 10.xx.x Update" (depending on your version).
Click "Update" next to the corresponding entry or click "Update All" at the top of the screen to refresh everything. You may need to restart your Mac for the update to take effect.
In general, the latest three major versions of MacOS are supported with security updates. For the latest security updates, see the Apple Security Updates page.

How to Install Updates Automatically
Your Mac can automatically find, download, and install various types of updates.
For macOS 10.4 Mojave or higher, go to System Preferences> Software Update and click the Advanced button to control the automatic updates. In macOS 10.3 High Sierra or earlier, you can find these options under System Preferences> App Store.
Check "Check for updates" to have your Mac automatically check for updates and display a notification in the upper-right corner of the screen when something is found. If you disable this, you must manually check for updates in this menu.
Enabling "Download New Updates When Available" will download all available system updates and notify you when they are ready for installation. You must install these updates manually by clicking the notification or by going to System Preferences> Software Update.
Select "Install macOS updates" or "Install app updates from" App Store "installs system and app updates automatically. You do not have to approve anything manually, but you may be prompted to restart your computer for the updates to take effect.
System data files are often only installed if you use a feature that relies on them. Some examples include speech recognition resources, enhancements to the sound output features of your Mac, fonts, and dictionary definitions. Security updates are downloads that fix known security vulnerabilities in your system, even if you are using an older version of macOS. This includes updates to the built-in macOS XProtect anti-malware feature.
We recommend that you keep the automatic updates enabled to keep your Mac safe and that all macOS features work as advertised. If you disable it, you must manually install these updates through the software update instead.
How to Update macOS to the Next Major Release
Upgrading macOS is different than upgrading as you switch from a major release to the next major release Next. These updates are provided once a year and lead to more significant changes than regular patches. The latest version of macOS can be found on the Apple website.
Note that downgrading your Mac to the previous version of macOS is difficult. Make sure every software you rely on is compatible with the latest version of macOS before you take the plunge. You may need to delete your Mac and reinstall macOS if you want to go back. You can also completely recover your current macOS system state from a Time Machine backup, provided that you have created one first.
Before installing updates to your core operating system, it's always a good idea to have a backup in case something goes wrong. You can create a free backup with Time Machine and a replacement hard drive. You can also use third-party software to create a bootable backup.
The latest version of macOS is always available through the Mac App Store. Launch the App Store by clicking the icon in your Dock or by clicking the Apple icon in the menu bar and selecting App Store.
New versions are often highlighted on the "Detect" tab (or on the "Highlighted" tab on older versions), or you can go to Search "macOS" to find the latest result.
 Click on "Get" in the App Store listing to start the download. You may need to enter your Apple ID password or use the Touch ID if your computer allows it. Downloading important operating system updates may take a while.
Once the download is complete, the update process should start automatically. You can stop the installer at any time and continue with the installation by starting the application "Install macOS [name]" (where "name" is the name of the latest version). Upgrading your operating system can take anywhere from 30 minutes to several hours, causing several restarts while the update is being applied.
Updating Your Mac App Store Apps
The Mac App Store makes it easy to find, install, and maintain the software on your Mac. All apps in the App Store are Apple-approved and have a sandbox in-house. This means that they run in a secure environment that should not damage your Mac.
Launch the App Store by clicking on the icon in your Dock. Click on the Apple icon in your menu bar and select "App Store" or press Command + Space and then search for it. Go to the Updates tab to see a list of available updates. You can choose to update each app individually, or click "Refresh All" instead.
If you want to automatically update your Mac App Store apps, start the App Store. Then click "App Store" in the upper left corner of the app store screen. Select "Settings" and make sure "Automatic Updates" is enabled.
Updating Apps Installed Outside the Mac App Store
Not all apps are available on the Mac App Store. If you need to manually install an app, it needs to be updated differently. Many apps can self-update, such as Google's Chrome browser (which automatically installs the latest version) and Microsoft Office, which uses a separate application called "Microsoft AutoUpdate" to apply updates.
Most apps automatically check for updates and notify you. You can force a check by locating the appropriate menu bar entry. Where it is depends on the app used. However, you can check the following:
- Under "App Name" in the menu bar, choose "Check for Update"
- Under "App Name," choose "About [19459047“]" and then "Check for Updates"
- Under "Help" in the menu bar, then "Check for Updates"
- in the application itself. For example, in Chrome, click Chrome> About Google Chrome and use the Updater here.
- About a dedicated update application, such as B. "Microsoft AutoUpdate" for Microsoft Office on Mac
If an app does not have the following capabilities: Update yourself. You may need to manually update it. First, find out which version of the app you're running by launching it, clicking on "App Name" in the upper-left corner of the screen, then selecting "About [App Name]".
Now go to the homepage of the app and see if a newer version of the app is available. If so, download it. When the download is complete, navigate to your Applications folder and locate the app. Drag the app icon to the trash in your dock. Note that you may lose some app data.
Install the app as usual.

How to Upgrade Mac System Tools and Drivers
If you're using a Mac, you generally need to do not worry about drivers. Apple recognizes your hardware and provides you with the latest updates for your specific configuration. Exceptions are third-party drivers and system tools.
If you are using a product such as Paragon NTFS that provides full write access to NTFS-formatted drives, a third-party driver may be installed. These tools often install a kernel extension and an icon in the system settings, usually at the bottom of the screen.
If you have such system tools or third-party drivers Search for the tweak in System Preferences. There should be an option for "Check for updates" or "Update now". You'll probably need to authorize changes with your administrator password, and then restart your Mac for the changes to take effect.
How to Update Safari Extensions  If you have installed Safari extensions (such as Evernote Web Clipper or Grammarly) from the Safari Extensions Gallery (macOS 10.13 or earlier) or the Mac App Store (macOS 10.14 or later), Updates are automatically installed.
If you manually installed a Safari extension from another source, you must manually update it. To start Safari, click "Safari" in the top left corner of the screen and then click "Settings." If updates are available, they will be displayed in the lower left corner of the window. If necessary, click Refresh next to each item.
Outdated Safari extensions can put your Mac at risk. Make sure you disable any outdated extensions that do not have updates. It is safe to assume that an extension is outdated if it is no longer maintained, eg. For example, if she has not received updates for over a year. You can find this information on the website of the extension. Disable an extension by deselecting the check box next to Safari Settings> Extensions.
Updating apps with homebrew
Homebrew is a package distribution system for macOS that lets you install apps from the command line (terminal). All apps you install through Homebrew can be updated with a single command. You must install the homebrew version of the app for this to work.
First you need to install Homebrew on your Mac. You can then use Terminal to search for apps to install with the following command:
Browsing Search Bureau
This searches for packages that match the search term "office". You install all the relevant packages of packages that you find with the following command:
Brew Barrel Libreoffice Installation
You can now run a single command to update homebrew-installed apps:
Brew barrel upgrade
This does not work for apps with built-in updaters like Google Chrome.

Update your software and stay on the safe side
Enable automatic updates whenever possible and periodically back up your Mac, to ensure maximum safety. Take the time to upgrade your computer to the latest version once a year. However, make sure that all your software is compatible before you press the shutter button.
Installing software updates is the best you can do to ward off newly discovered vulnerabilities. If you rely on an app that is no longer actively maintained, you should look for an alternative that will not endanger you.
