So, you've decided to download an older version of Mac OS X. There are many reasons that could point you to this radical decision. To begin with, some of your apps may not be working properly (or simply crash) on newer operating systems. Also, you may have noticed your Mac's performance went down right after the last update. Finally, if you want to run a parallel copy of Mac OS X on a virtual machine, you too will need a working installation file of an older Mac OS X. Further down we'll explain where to get one and what problems you may face down the road.

A list of all Mac OS X versions
MacOS (originally named 'Mac OS X' until 2012 and then 'OS X' until 2016) is the current Mac operating system that officially succeeded the classic Mac OS in 2001. Although the system was originally marketed as simply 'version 10' of Mac OS, it has a history that is largely independent of the classic Mac OS. It is a Unix-based operating system built on NeXTSTEP and other technology developed. Learn how to create and deploy a FileVault recovery key for Mac computers in your company, school, or other institution. If you're using FileVault in Mac OS X Snow Leopard, you can upgrade to FileVault 2 by upgrading to OS X Lion or later. After upgrading OS X, open FileVault preferences and follow the onscreen instructions to upgrade FileVault.
We'll be repeatedly referring to these Apple OS versions below, so it's good to know the basic macOS timeline.
Cheetah 10.0 | Puma 10.1 | Jaguar 10.2 |
Panther 10.3 | Tiger 10.4 | Leopard 10.5 |
Snow Leopard 10.6 | Lion 10.7 | Mountain Lion 10.8 |
Mavericks 10.9 | Yosemite 10.10 | El Capitan 10.11 |
Sierra 10.12 | High Sierra 10.13 | Mojave 10.14 |
Catalina 10.15 |
STEP 1. Prepare your Mac for installation
Given your Mac isn't new and is filled with data, you will probably need enough free space on your Mac. This includes not just space for the OS itself but also space for other applications and your user data. One more argument is that the free space on your disk translates into virtual memory so your apps have 'fuel' to operate on. The chart below tells you how much free space is needed.
Note, that it is recommended that you install OS on a clean drive. Next, you will need enough disk space available, for example, to create Recovery Partition. Here are some ideas to free up space on your drive:
- Uninstall large unused apps
- Empty Trash Bin and Downloads
- Locate the biggest files on your computer:
Go to Finder > All My Files > Arrange by size
Then you can move your space hoggers onto an external drive or a cloud storage.
If you aren't comfortable with cleaning the Mac manually, there are some nice automatic 'room cleaners'. Our favorite is CleanMyMac as it's most simple to use of all. It deletes system junk, old broken apps, and the rest of hidden junk on your drive.

STEP 2. Get a copy of Mac OS X download
Normally, it is assumed that updating OS is a one-way road. That's why going back to a past Apple OS version is problematic.

If you succeed in downloading the OS installation, your next step is to create a bootable USB or DVD and then reinstall the OS on your computer.
How to download older Mac OS X versions via the App Store
If you once had purchased an old version of Mac OS X from the App Store, open it and go to the Purchased tab. There you'll find all the installers you can download.

- Click the App Store icon.
- Click Purchases in the top menu.

But as it often happens, workarounds are possible. There is still a chance to download the installation file if you have an access to a Mac (or virtual machine) running that operating system. For example, to get an installer for Lion, you may ask a friend who has Lion-operated Mac or, once again, set up a virtual machine running Lion. Then you will need to prepare an external drive to download the installation file using OS X Utilities.
After you've completed the download, the installer should launch automatically, but you can click Cancel and copy the file you need. Below is the detailed instruction how to do it.
