You may find that after the latest update your computer runs slower, your apps don’t function, or that the programs you need to run are not yet compatible with the upgrade. Maybe as a developer, you want to create a test environment to ensure your software runs properly in all available versions of OS X - check out the infographic below. Or you may simply like the look of the old version better (no judgement) and not want to upgrade until absolutely necessary.

Get Setapp, a collection of Mac apps that strengthen your macOS. Whenever you decide to downgrade, your apps will travel with you.

How to Install Old OS X on Your Mac

Although you might think that going back to the old macOS is not possible by looking at the App Store Updates tab, it’s actually quite easy to do. In this article, we’ll take you through everything you need to download and install an old OS X on your Mac.

Prepare your Mac first

Make sure you are ready to downgrade your operating system by checking in with what version of OS X you already have and ensuring you have enough hard drive room to download the older version. Clicking the apple in the top left corner of your desktop and selecting About This Mac will allow you to see what OS X version you are currently running. Tabbing over to Storage will let you know how much disk space you have available. You’ll need around around eight gigabytes free depending on which macOS you downgrade to.

Even if you do have enough space, it’s a good idea to clean your computer before installing the desired operating system. You can, of course, do so manually by deleting unused files and uninstalling old software to free up disk space. Depending on how tidy you are, this might take quite a bit of time.

To make things easy, use a specialized app like CleanMyMac, which will quickly free up space by detecting unused apps and large files, and offering to completely delete them, with all their hidden corresponding files, in one quick click.

Optimizing your Mac with CleanMyMac is effortless:

Launch CleanMyMac
Select the Smart Scan tab and click Scan
Review Details to see the list of suggested optimizations
Click Clean

To uninstall certain apps, find the Uninstaller tab and select the apps you haven’t been using for a while.

To create a new backup with Get Backup Pro:

Connect your external hard drive
Click the plus icon in the bottom left corner
Type in the name for your backup
Choose your external drive as a destination
Adjust all the settings according to your preference and click OK
Tap the play button once you ready to perform the backup

Download the OS X you want

Once you have space on your computer, figure out what version of OS X you would like to install. You can see all previous versions of OS X your Mac has installed by opening up the App Store and clicking the icon in Applications. Tab to the Purchase page of the menu and scroll down to find the line for previous operating systems. Clicking the install button of the macOS you want will begin downloading the file.

What if I can’t find the version I want in the app store?

If your goal is to download a version of macOS that you have not already used, or, that was not available as an update from the App Store after you bought your Mac, you may need to purchase it. The earliest versions, OS X Lion and OS X Mountain Lion are available on the Apple Store’s website and arrive to you via email for download. OS X Snow Leopard ships as a boxed version and requires a disk drive to install.

It could be helpful to know where you sit on the timeline of macOS X updates. Below is a chronological list of all the updates beginning with the most recent update, High Sierra, released in 2017:

OS X High Sierra 10.13
OS X Sierra 10.12
OS X ElCapitan 10.11
OS X Yosemite 10.10
OS X Mavericks 10.9
OS X Mountain Lion 10.8
OS X Lion 10.7, released in 2011

Visiting the Apple Support’s Downloads page makes it easy to search for any version of macOS you might need, and most are available for free. Downloads for previous versions of OS X are linked below and include:

Alternative sources for downloading macOS

If you can’t find the version you want from Apple, ask a friend who is running the macOS you’re looking for to make a copy of the installer file for you. Downloading a .dmg file from a torrent site may seem a quick solution, but it means risking your security. Alternatively, you could hit up your nearest Apple Store. They will likely have image files of all the different versions of the software and help you install it right there as well.

Install the macOS

If you download the file from the App Store, the installer will start immediately. Foll
