How to get older versions of macOS: Download Catalina, Mojave, and more

Do you need the installation files of an old macOS? We explain where to download Catalina, Mojave, El Capitan, High Sierra, and other versions of macOS.

There are several reasons you might want to download and install older versions of macOS or Mac OS X. Maybe you need to use software not compatible with the latest version, or maybe you don’t like the new version of macOS you just installed.

It may also be the case that you’re a developer and need to run multiple versions of macOS and Mac OS X at once to make sure your software works well on all of them.

This article will explain how to get older versions of macOS, including Catalina, Mojave, El Capitan, Sierra, Yosemite, and even older versions of Mac OS X. We teach you how to get the installation files to have them on your Mac.

Instead, if you want to revert to a previous version of macOS, you’ll be interested in our article How to rollback from the macOS Big Sur on Mojave? 5 Steps Steps. Now, you should know that older versions of macOS cannot be installed on Macs with M1.

Where to download an old version of macOS

Before installing an older version of macOS or Mac OS X, you’ll need to get a hold of the installer for the version of macOS you want to use. Luckily, it’s possible to get those files quickly, as long as you know where to look for them in the Mac App Store.

Later you will find the necessary links, and we will explain how to get the installers of these versions of macOS:

Of course, keep in mind that it seems that the links that we offer below only work from Safari, so we advise you to switch to the Apple browser before continuing. You should also close the Mac App Store, or the link might not work.

On the other hand, it is not possible to get Mac OS X Snow Leopard with this method, but we will develop that in due course. We will tell you how also to get a copy of Leopard, Lion, and Mountain Lion.

How to download macOS Catalina?

You can download the macOS Catalina installer from the Mac App Store, as long as you know where to find the magic link. Or you can download it from our website archive: Download macOS Catalina

1. Click this link to open the Mac App Store on the page dedicated to Catalina. As we said, use Safari and close the Mac App Store before opening it.

2. Now, click on the ‘Get’ button.

3. The ‘Software Update’ panel will open, indicating that the update is being sought. In the end, you will see a message asking if you are sure you want to download macOS Catalina.

You may think it’s an update and not the full version, but you’ll see that the download size (about 6 GB) indicates that it’s the full Catalina installer.

4. Once the installer has been downloaded, do not click ‘Install.’ If you do, the installer will be removed automatically.

5. You should find the Install macOS Catalina app in your ‘Applications’ folder.

How to download macOS Mojave?

It is also possible to access the Mojave installer by clicking on the Mac App Store link. As we have indicated above, for it to work, you will need to open it in Safari and after you have closed the Mac App Store. If it is open, it will not work. Or you can simply download it from our website archive:

Download macOS Mojave

Follow the steps in the previous section to download the macOS Mojave installer.

How to download macOS High Sierra?

It is also possible to download High Sierra using this link (use Safari and close the App from the Mac App Store first, of course). And, as before, follow the same steps indicated to download High Sierra. You can also download it from our website archive:

Download macOS High Sierra

How to download macOS Sierra, macOS El Capitan or macOS Yosemite?

Apple offers files .dmg of its older macOS versions. Download them from Safari. A disk image called InstallOS.dmg will be downloaded, and then you will have to locate the pkg installer within this disk image.

What to do if the link to the Mac App Store doesn’t work?

We’ve said before that, in our experience, usually the reason one of these links doesn’t work is that you’re not opening them from Safari or because you already had the Mac App Store app open before you did.

Now, even following these guidelines, you may be experiencing problems.

It may be the case that, although the link does work, you see an error message when you try to download it. We know that there are people who have encountered this error, but we have not. In this case, we suggest you download the installer from an older Mac.

On the other hand, you may also encounter problems downloading an old version of macOS that is not compatible with your Mac. Usually, when Apple introduces a new Mac, it is not compatible with the macOS version before the one it had installed when it went on sale.

Other ways to get older macOS versions

If you have an older version of macOS installed (or know of someone who has one), you should be able to easily see older versions of macOS and even Mac OS X on the Mac App Store. How easy you’ll find them will depend on the version of macOS installed on your Mac.

Before the arrival of macOS Mojave in 2018, installers of older versions of macOS could be searched for or found from the ‘Purchases’ tab (even if you didn’t have to pay anything for them).

However, when Apple introduced Mojave, it made changes to the Mac App Store, which is no longer the case. Luckily, with the links you’ll find in the previous sections, you still have access to those download pages from the Mac App Store.

If you have access to a Mac with an older version of macOS, sign in to the Mac App Store with your password and download the Mojave installer to your Mac.

Once the installer has been downloaded, do not install it. If you do, the installer will be removed automatically. You will find the installer in the ‘Applications’ folder, from which you can copy it to the Mac you want or create a bootable installer.

You may download the installer using Terminal, but we haven’t been able to test this method personally.

You may also find old versions of macOS on the Apple page, although it is worth noting that these are only updates and not full versions, so they will surely not help you much.

The only thing you really shouldn’t do is go to a torrent site and download a copy of OS X that you want, as this can be dangerous. Pirated copies of Apple software may be created to allow hackers access to your Mac.

How to download Mac OS X?

If you have access to a Mac with OS X Yosemite or earlier, you might be able to see older versions of Mac OS X in the Mac App Store. This is the case of Yosemite, Mavericks, and Mountain Lion.

Download macOS Mavericks

It should be noted that you will only see the old versions of Mac OS X that you have downloaded here: if you have never done it (or if you have never done it in the Mac App Store), that version will not be in the ‘Purchases’ section.

Another reason why the Mac OS X version might be absent is that your computer came with that version factory installed. We will deal with this case later.

Here’s how to get an older version of Mac OS X from the App Store (this only works if you’ve downloaded it in the past):

1. Open the Mac App Store and sign in.

2. Click on the ‘Purchases’ section.

3. Swipe down to find the copy of OS X or macOS you want.

4. Click ‘Install.’ Clicking ‘Install’ will not install the software but will download the installation application in the ‘Applications’ folder.

However, you won’t be able to install this older version of the operating system directly on a Mac running a newer version of OS X or macOS.

Can’t find Mac OS X in the ‘Purchases’ section?

If you know, you’ve previously downloaded the version of macOS you’re looking for, but you don’t see it in the ‘Purchases’ section, check the following:

1. Sign out of the App Store and sign in again.

2. If there’s a chance you downloaded it while logged in with a different Apple ID (maybe a work-related one), sign in with that ID.

3. Alternatively, find someone who has downloaded that version of the Mac operating system and ask them to download the installation file for you.

4. If you have never downloaded the Mac OS X version, go to step 3 and find a person who has. Ask them to download the Mac OS X installer for you.

Luckily, the OS X copy isn’t unique to your account, so that it will install on any Mac.

How to download OS X Lion and Mountain Lion?

Until June 2021, it was possible to buy OS X 10.7 Lion or Mountain Lion from Apple. Apple no longer charges for downloading old versions of its operating system, but you can download them directly from its website.

You can download these versions by clicking on these links:

Download macOS Mountain Lion

Download macOS Lion

How to download OS X Snow Leopard?

The version of Mac OS X you’re looking for may never have been available from the Mac App Store. This is the case with Snow Leopard, the first version of Mac OS X that arrived simultaneously as the App Store.

This way to download updates and new apps for Mac OS X was introduced with Snow Leopard and meant that anyone with a Mac running Mac OS X 10.5 Leopard or earlier cannot access the Mac App Store to download anything.

Until 2021, Apple sold a version of Mac OS X 10.6, but now it has already eliminated that possibility. However, this should not be a big problem because you can still download the Lion or Mountain Lion updates, as we have explained before.

Download Snow Leopard

How to download OS X Leopard or earlier

If the old version of the operating system you’re looking for predates Snow Leopard and you have a developer account, you may be able to get it from

If you search within the OS X category, you will see downloads of all versions of OS X, at least from version 10.3 to 10.6.

Download macOS Leopard

Download macOS Tiger

Download macOS Panther

Download macOS Jaguar

Download macOS Puma

Download macOS Cheetah

You may be able to access the developer section of the website. Still, you will only be able to access specific software downloads if your Apple ID is associated with a paid Apple developer program.
