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.
Once you’re formatted the drive, click Disk Utility’s Restore tab. Into the Source field drag the disk image of your Snow Leopard installer (likely called Mac OS X Install DVD.dmg).
A list of all Mac OS X versions
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|
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. The main challenge is to download the OS installation file itself, because your Mac may already be running a newer version. 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. However, it doesn’t always work that way. The purchased section lists only those operating systems that you had downloaded in the past. But here is the path to check it:
- Click the App Store icon.
- Click Purchases in the top menu.
- Scroll down to find the preferred OS X version.
- Click Download.
This method allows you to download Mavericks and Yosemite by logging with your Apple ID — only if you previously downloaded them from the Mac App Store.
Without App Store: Download Mac OS version as Apple Developer
If you are signed with an Apple Developer account, you can get access to products that are no longer listed on the App Store. If you desperately need a lower OS X version build, consider creating a new Developer account among other options. The membership cost is $99/year and provides a bunch of perks unavailable to ordinary users.
Nevertheless, keep in mind that if you visit developer.apple.com/downloads, you can only find 10.3-10.6 OS X operating systems there. Newer versions are not available because starting Mac OS X Snow Leopard 10.7, the App Store has become the only source of updating Apple OS versions.
Purchase an older version of Mac operating system
You can purchase a boxed or email version of past Mac OS X directly from Apple. Both will cost you around $20. For the reason of being rather antiquated, Snow Leopard and earlier Apple versions can only be installed from DVD.
Buy a boxed edition of Snow Leopard 10.6
Get an email copy of Lion 10.7
Get an email copy of Mountain Lion 10.8
The email edition comes with a special download code you can use for the Mac App Store. Note, that to install the Lion or Mountain Lion, your Mac needs to be running Snow Leopard so you can install the newer OS on top of it.
How to get macOS El Capitan download
If you are wondering if you can run El Capitan on an older Mac, rejoice as it’s possible too. But before your Mac can run El Capitan it has to be updated to OS X 10.6.8. So, here are main steps you should take:
1. Install Snow Leopard from install DVD.
2. Update to 10.6.8 using Software Update.
3. Download El Capitan here.
“I can’t download an old version of Mac OS X”
If you have a newer Mac, there is no physical option to install Mac OS versions older than your current Mac model. For instance, if your MacBook was released in 2014, don’t expect it to run any OS released prior of that time, because older Apple OS versions simply do not include hardware drivers for your Mac.
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.
STEP 3. Install older OS X onto an external drive
The following method allows you to download Mac OS X Lion, Mountain Lion, and Mavericks.
- Start your Mac holding down Command + R.
- Prepare a clean external drive (at least 10 GB of storage).
- Within OS X Utilities, choose Reinstall OS X.
- Select external drive as a source.
- Enter your Apple ID.
Now the OS should start downloading automatically onto the external drive. After the download is complete, your Mac will prompt you to do a restart, but at this point, you should completely shut it down. Now that the installation file is “captured” onto your external drive, you can reinstall the OS, this time running the file on your Mac.
- Boot your Mac from your standard drive.
- Connect the external drive.
- Go to external drive > OS X Install Data.
Locate InstallESD.dmg disk image file — this is the file you need to reinstall Lion OS X. The same steps are valid for Mountain Lion and Mavericks.
How to downgrade a Mac running later macOS versions
If your Mac runs macOS Sierra 10.12 or macOS High Sierra 10.13, it is possible to revert it to the previous system if you are not satisfied with the experience. You can do it either with Time Machine or by creating a bootable USB or external drive.

Before you do it, the best advice is to back your Mac up so your most important files stay intact. In addition to that, it makes sense to clean up your Mac from old system junk files and application leftovers. The easiest way to do it is to run CleanMyMac X on your machine (download it for free here).
Visit your local Apple Store to download older OS X version
If none of the options to get older OS X worked, pay a visit to nearest local Apple Store. They should have image installations going back to OS Leopard and earlier. You can also ask their assistance to create a bootable USB drive with the installation file. So here you are. We hope this article has helped you to download an old version of Mac OS X. Below are a few more links you may find interesting.

I had a guy bring me in an old Mac Book Pro that had a corrupted hard drive. I saved his Data but then realized his computer was so old that I was going to have trouble getting a copy of OSX installed. His computer was no longer supported on current OSX releases. To make things worse his DVD drive wouldn't read a install disk. So this post is the result of me finding a way to resurrect an old Mac Book Pro. I hope it will help someone else in a similar situation.
Before starting this tutorial, ensure that you have a USB drive with at least 8GB of storage as well as a Leopard, or Snow Leopard retail DVD or disk image. Grey DVDs that were included with a Mac at the time of purchase cannot be used to make USB boot drives as they do not include drivers for Macs other than the computer it was shipped with. In this tutorial I will be creating a Snow Leopard USB install disk. The steps are the same to create one for Leopard.
Creating a Snow Leopard USB Boot Drive Using Disk Utility
Start by launching Disk Utility on the Mac. To do this, you can either search for the application in Spotlight or find it in the Applications folder. Locate the USB drive on the left-hand side of the window and click on its name, not its partition.
Format the USB drive
- Click the Partition tab
- Under the Partition Layout header click on the 1 Partition option in the drop-down menu
- Click the Format drop-down menu and select Mac OS Extended (Journaled).
Bear in mind that this will erase all data from the USB drive, so backup any important files before proceeding.
Mac Os 10.5 Leopard Download
- To format the USB drive drive, click the Apply button in the lower right-hand corner of the Disk Utility window.
Snow Leopard, DVD or Disk Image
- Locate a Snow Leopard disk image or DVD on the Mac
- If you're using a disk image, mount it to the desktop
- In the Disk Utility window, click the Restore tab in the USB drive's menu
In the center of the window you'll see two boxes: one labeled Source and another Destination.
- Drag-and-drop the USB drive's partition into the Destination box
- Drag-and-drop the Mac OS X Install Drive disk into the Source box
- At the bottom right-hand corner of the screen and click the Restore button
Disk Utility will restore the OS X Install DVD or disk image to the USB drive; this process may take anywhere from 20 minutes to an hour depending on how quick the Mac is.
Using The Snow Leopard USB Drive
Now that you've created a Snow Leopard USB drive, let's use it to install OS X Snow Leopard as well as access Terminal, Disk Utility, and other OS X utilities.
- Power down the Mac and reboot while holding the Option key
- Select the OS X Install DVD from the boot menu using the arrow keys on the Mac's keyboard
- Select the language you'd like to use when prompted
Installing OS X Snow Leopard
To install OS X Snow Leopard from the USB drive, you'll need to reformat the Mac's hard drive. To do this, look towards the top of the screen and click on Utilities from the top menu and then click Disk Utility from the drop-down menu.
Formatting The Mac's Hard Drive
- Click on the Mac's hard drive name
- Click the Erase tab
- Select Mac OS Extended (Journaled) from the Format drop-down menu
- Name the drive whatever you'd like
Please note that all data on the Mac's hard drive will be erased, so backup all important files before proceeding.
- Press the Erase button to format the Mac's hard drive
Starting The Snow Leopard Installer
- Quit Disk Utility by pressing Command-Q on the keyboard
- Press the Continue button
- From the center of the window, select the Mac's hard drive
- Press the Install button
OS X Snow Leopard may take a bit of time to install depending on the Mac's hardware. Upon completion, the Mac will restart and prompt you to create an account.
Disk Utilities on the Snow Leopard USB Drive
Additionally, you can access Disk Utility, Terminal, Safari (to access Apple help articles. not general browsing) and other Mac utilities from the Snow Leopard USB drive.
Boot the Mac to the USB drive using the steps shown above and click on the Utilities button from the top bar. You can access all available utilities from this drop-down menu.
It's nice to have these utilities available to use from the USB drive, especially Disk Utility. For example, if you believe your hard drive has died or is corrupted, you can boot your Mac from the USB drive and use Disk Utility to check the the hard drive's SMART status and repair said drive.
OS X Snow Leopard USB Drive, Completed
In this tutorial, I've shown you how to create a bootable OS X 10.6 Snow Leopard USB drive. You can now use the USB drive to upgrade, maintain and restore Macs to OS X 10.6.
