Old versions of macOS may seem unproductive at first glance. Newer operating systems indeed offer additional capabilities. As a result, they get more updates. As time went on, Apple stopped maintaining older versions of macOS, which meant no longer receiving security updates for them.

However, there are some compelling reasons to go ahead and do it. Older Macs, for example, tend to operate better on older versions of macOS. Big Sur and Monterey can't run on later macOS versions like Yosemite and Mavericks. Installing an older version of the operating system may be your best option in these cases.

Why Do You Need an Old Version of macOS?

 You may wish to install an older version of macOS or Mac OS X for several different reasons, including the following:

  • It's also possible that you dislike the version of macOS that you currently have installed on your computer.
  • You may wish to downgrade to an older version of macOS because you depend on certain software that you just realized is incompatible with the most recent release of macOS.
  • Your Mac device doesn't fit compatible with the newest version.
  • Perhaps you are a software developer who must test your application on several macOS versions to ensure it functions properly across all of Apple's operating systems.

The good news is that you can install an earlier version of macOS, and we will explain how to do so. Regardless of why you want to install an older version of macOS, you may do so.

Check Compatibility

If you want to utilize an older version of macOS, you can do it without any issue. However, when you attempt to run a more recent version on an older Mac, you have a greater chance of encountering issues. Because Apple withdraws support for older model PCs that can't run newer OS X versions, there are ways to avoid it, but doing so will likely slow down your Mac.

Step 1: Click the "I" icon located in the upper left corner of the screen.

Step 2: Choose the About This Mac option.

Step 3: You will see your Mac's model name and its release year of it in the Overview area.

Step 4: Look up the technical specifications for the version of macOS that you wish to install.

Step 5: If the model of your Mac computer is included on the list of compatible devices, you can downgrade to an earlier version of macOS.

How to Download Old Versions of macOS

1. Get it from the Mac App Store

Here is how you can use it from the App Store on Mac:

When you upgrade your Mac to the most recent version of macOS, the installer may be downloaded quickly and conveniently from the Apple menu.

However, if you search for macOS Big Sur, macOS Catalina, or any previous versions of macOS in the App Store, it will not appear in the results.

2. Reinstall macOS Using a Bootable USB Drive

After you have made a USB device bootable, you will be able to use that drive to install macOS. To do this, you will need to choose it when your Mac starts up. To reinstall macOS, follow these steps while using a bootable USB drive:

Step 1: You may either restart your Mac or turn it on.

Step 2: Make sure you hit and hold the Option key before the chime.

Step 3: Continue holding it down until a menu with several boot choices appears.

Step 4: Choose the USB disk you want to use and wait for it to load.

You don't need to do anything special if you're installing to an external disk or a new partition; all you have to do is follow the installer's instructions.

However, Apple does not let you downgrade from the macOS version that you are now using. To install an earlier version of macOS on your primary storage device, you will first need to erase everything on it entirely.
