This article explains how you can fix the software update problem. More specifically, the focus of this article is on what you can do to when your Mac won’t update to the latest version of macOS.

Some Mac users, unfortunately, have been and continue to be affected by various macOS software update issues where they may experience a stalled macOS update. By stalled, we mean that macOS updates won’t download and install successfully.

Sometimes, you may see an error message saying “The macOS installation couldn’t be completed” or “macOS could not be installed on your computer”.

Mac Won’t Update?

Please try the tips belove if you are unable to update your computer:

It is important that you back up your Mac before you do anything.

There could be a variety of reasons for this. Before you do anything:

  • Make sure there is enough space to download and install an update. If not, you may see error messages. To see if your computer has enough room to store the update, go to the Apple menu > About This Mac and click the Storage tap. You can easily free up storage space on your Mac.
  • If you see a “Update Not Found” error, see this article.
  • Make sure that you have an Internet connection to update your Mac. You can troubleshoot your connection.
  • Be patient. An update may take some time. Just waiting may fix your problem. Sometimes more than a few hours. Do not put your Mac to sleep or closing its lid. Also ensure than your Macbook, if it is a Macbook, it is plugged it into AC power.
  • If the update does not complete, your computer may seem stuck or frozen, for an extended time, try to restart your computer by pressing and holding the power button on your Mac for up to 10 seconds.
  • If you have any external hard drives or peripherals connected to your Mac, try removing them. And try to update now.
  • Reset PRAM on your Mac and then try again. To reset PRAM, turn off your Mac and then turn it on and immediately press and hold the Option, Command, P, and R keys together for about 20 seconds.
  • It is possible that your Mac may unable to reach the update server. There could be two reasons for this:
    • You may have a slow internet connection. You may want to restart your router and modem to fix this problem. If you are using a Wi-Fi connection, try a wired connection, if possible.
    • Or there could be issues with Apple servers. It is possible that Apple servers are overloaded as a lot of people may be trying to update. You can check if Apple servers are experiencing issues.

If you are still having issues, then you may try the followings:

Safe mode

Try updating your Mac in safe mode. Here is how:

  • Startup your Mac in safe mode. To do that, turn off your Mac and then turn on your Mac and immediately press and hold the Shift key until you see the login screen. Then release the Shift key. And login.
  • Now your computer is in safe mode. Try to update now.
  • Then exit safe mode when you are done (in either case). To exit safe mode, restart your Mac normally, without pressing the Shift key.

Combo update

You can use a combo update to install Mac updates. Please note that before you continue, you may want to back up your Mac. You can back up with Time Machine or you can use iCloud.

Please note that combo updates let you update your Mac from a prior version of macOS within the same major release. A combo update is a combined update that means that it contains all of the changes since the original release of that major version. This further means that, using a combo update, you can update from macOS 10.15 directly to Mac OS X 10.15.2, skipping the 10.15.1. But you cannot go from, let’s say, 10.14.x to 10.15.x. For example, using a combo update, you cannot upgrade from macOS Mojave to macOS Catalina.

Please note that combo updates are huge. Here is how you can use them:

  • Visit Apple’s combo updates site: https://support.apple.com/downloads/macos
  • Find the right combo update. And download it. As stated above, they can be huge. The combo will download as a .dmg file.
  • Now quit all apps on your Mac.
  • Double-click the downloaded file, if it does not start automatically.
  • Follow the onscreen instructions.

Using macOS Recovery to update your Mac

If you still could not update, you may try this. To do this, you need to restart your Mac from macOS Recovery. Using the method below, you will be able to upgrade to the latest macOS that is compatible with your Mac. Here is how:

  • Turn off your Mac.
  • Turn on your Mac and immediately press and hold the Option-⌘-R keys together until you see the Apple logo or the spinning globe icon.
  • Login.
  • Click Reinstall macOS and follow the onscreen instructions.

macOS Big Sur takes the most advanced operating system in the world to a whole new level of power and beauty, making your apps look better than ever on an all-new interface. New widget features and the new widget gallery help you deliver more value to your users. Adding intelligence to your apps with machine learning is even simpler and more extensive with new tools, models, training capabilities, and APIs. You can create more powerful Mac versions of your iPad apps with Mac Catalyst. And you can now easily bring your extensions to Safari — and to the App Store.

All-new Interface

macOS Big Sur brings a new design that’s been finely tuned for the powerful features that make a Mac a Mac. Core features, such as the menu bar and Dock, take advantage of the large Mac display, with translucent backings and spacious pull-down menus. The new Control Center, designed just for Mac, provides quick access to controls while keeping the menu bar clutter-free. Notification Center puts recent notifications and powerful new widgets together in a single view for at-a-glance information as you work. And a streamlined new design for apps features full-height sidebars and integrated toolbar buttons.

Widgets

Apple Mac Os X Download

Easily build widgets using the WidgetKit framework and the new widget API for SwiftUI. Widgets now come in multiple sizes, and users can visit the new widget gallery to search, preview sizes, and add them to Notification Center to access important details at a glance.

Safari Extensions

Apple mac os x latest version out now

With support for the popular WebExtension API, it’s even easier to bring powerful extensions to Safari. Xcode 12 even includes a porting tool to streamline the process.

The new Extensions category on the Mac App Store showcases Safari extensions, with editorial spotlights and top charts to help users discover and download great extensions from the developer community.

Machine Learning

With macOS Big Sur, creating apps that leverage the power of machine learning is even easier and more extensive with additional tools in Core ML for model deployment, new models and training capabilities in Create ML, more APIs for vision and natural language, and improved resources for training on Mac and converting models to Core ML format.

Mac Catalyst

Create even more powerful Mac versions of your iPad apps. Apps built with Mac Catalyst now take on the new look of macOS Big Sur and help you better define the look and behavior of your apps. You can choose to turn off automatic scaling of iPad controls and layout, allowing you to precisely place every pixel on the screen. Provide full control of your app using just the keyboard, take advantage of the updated Photos picker, access more iOS frameworks, and more.

User privacy on the App Store.

Later this year, the Mac App Store will help users understand apps’ privacy practices. You’ll need to enter your privacy practice details into App Store Connect for display on your product page.
