Update from high sierra to catalina

An outdated Mac is more susceptible to bugs, crashes, and even viruses (yes, Macs can get them too). And if you leave updates waiting for too long, your favorite apps might stop working altogether.

In November 2020, Apple released macOS Big Sur, the latest version of its famous operating system. And if you're currently working on a Mac, now is a good time to update your computer.

How to update your Mac computer

There are two major ways to update your Mac, and which one you use will depend on what macOS version you're currently running. For information on how to check which macOS version you currently have, read our article, 'How to check which version of macOS your Mac computer is running and check for new updates.'

Before going forward with updates, it's a good idea to backup your computer to ensure no data is lost in the process. You'll also need to be connected to the internet.

After that, keep in mind that the updates may take several minutes to install, depending on how many of your apps are due for updates.

2. There are two menus here that you can use to check for updates. Click either 'System Preferences' or 'About This Mac...'

From the above screen, you'll be given the option to update your Mac. Any Mac computer released in 2012 or later should be able to update to at least macOS Catalina. If your Mac is so old that it can't even do that, it might be time to buy a new model.

And, for future reference, don't worry about accepting an update and then having your computer unexpectedly restart — you'll be notified beforehand if a restart is required.

MacOS Catalina Patcher (formerly macOS Mojave Patcher, macOS High Sierra Patcher and macOS Sierra Patcher) is a small yet powerful tool that can help you create a bootable USB drive that can be used to install macOS Catalina on Mac computers older than mid 2012, basically acting as a macOS Mojave patch for unsupported Macs.

macOS Catalina Patcher (formerly macOS Mojave Patcher, macOS High Sierra Patcher and macOS Sierra Patcher) is a small yet powerful tool that can help you create a bootable USB drive that can be used to install macOS Catalina on Mac computers older than mid 2012, basically acting as a macOS Mojave patch for unsupported Macs.

The tool extends the list of compatible hardware to the Mac Pro, iMac and MacBook Pro computers released in early 2008, Aluminum Unibody MacBooks or MacBooks Air manufactured in late 2008, or white MacBooks and Mac Minis produced in early 2009.

Updating From High Sierra To Catalina Version

Get the macOS Catalina Installer app and make sure you have access to a compatible USB drive

To be able to use the app you must make sure that you have a USB drive that has at least 8 GB available, and that you have the macOS 10.15 Catalina installer app on your Mac.

Note that you can download the macOS image from the Mac App Store application only on a machine that supports Catalina: otherwise, you must find an alternative solution.

For your convenience, macOS Catalina Patcher offers you the possibility to download the image through its interface: just navigate to the Tools menu.

At the same time, you must prepare the USB drive with the help of the built-in Disk Utility application: just format the disk using the Mac OS Extended (Journaled) standard.

Updating From High Sierra To Catalina

Within the main window, you must simply load the macOS 10.15 image you want to use and select the target USB drive. The app will verify the image to make sure everything is OK, and all you have to do is press the Start Operation button.

You have the option to monitor the process in the macOS Catalina Patcher main window, and the utility lets you know when the task is complete.

Worth mentioning is that after you install the OS by using the macOS Catalina Patcher bootable drive, you must launch the macOS Post Install utility to get access to patches specifically designed for your Mac’s model.

Hackintosh Update From High Sierra To Catalina

Make a bootable drive that allows you to install Catalina on unsupported Macs

Bottom line, if your Mac has been manufactured before early 2008, chances are that you will not be able to install macOS Catalina on your computer.

All things considered, macOS Catalina Patcher is a small and user-friendly utility designed to help you bypass this limitation if your Mac is not in macOS Catalina's compatibility list, created to be used as an unsupported Mac Mojave patch.

Is your Mac up to date with the latest version of the Mac operating system? Is it using the version required by some product that you want to use with your Mac? Which versions are earlier (older) or later (newer, more recent)? To find out, learn which version is installed now.

If your macOS isn't up to date, you may be able to update to a later version.

Which macOS version is installed?

From the Apple menu  in the corner of your screen, choose About This Mac. You should see the macOS name, such as macOS Big Sur, followed by its version number. If you need to know the build number as well, click the version number to see it.

Which macOS version is the latest?

These are all Mac operating systems, starting with the most recent. When a major new macOS is released, it gets a new name, such as macOS Big Sur. As updates that change the macOS version number become available, this article is updated to show the latest version of that macOS.

If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps that are installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar, and Photos.
