Mac OS X & macOS names. As you can see from the list above, with the exception of the first OS X beta, all versions of the Mac operating system from 2001 to 2012 were all named after big cats. Nov 12, 2020 Starting with Mac OS X Cheetah back in 2001, every Mac operating system was version 10.1, 10.2, etc. Last year's macOS Mojave was 10.14, for example. Last year's macOS Mojave was 10.14, for.
Updated and republished for macOS 11.2.2; skip it unless you really really care about all the macOS releases. Originally published on November 14th, 2005.
Below the break is a table showing all major releases of macOS (previously Mac OS X) from the public beta through the latest public version, which is 11.2.2, as of February 25th, 2021—the 146th release in total.

Note: The Days column reflects the number of days between releases.
Some entries may appear out of chronological order (i.e. 10.5 is shown on Oct 26, but above Nov 14 for 10.4.11). This is to keep the version numbers in the proper order, even when an older OS received an update after a major new release came out. This has happened a few times over the years.
Some random notes, updated from the original post:
- Starting with the Public Beta and up through 11.2.2, there have been 146 macOS releases, both major and minor. This figure includes the one odd macOS X release: 10.2.7. This version was only for the then-new PowerMac G5 and the flat panel iMac G4, and was never generally released.
- As of February 25th, 2021 (11.2.2's release date), it's been 7,470 days since the Public Beta was released. So on average, we've seen some sort of update every 51.2 days.
- The shortest time period between any two releases is six days, which is how quickly the 10.15.5 Supplemental Update 1 came out after the 10.15.5 release.
- The longest time period between any two minor releases is 165 days, which was how long we waited for the 10.4.9 update. (Tecnically, it's actually the 192 day interval between the Mac OS X Public Beta and version 10.0, but I'm counting from the official 10.0 release.)
- The smallest update was 10.3.1, at only 1.5MB. The largest (non-combo, non-main OS release) update was 10.15.1 at 5.3GB.
- The '???' entry for Size on a given release indicates I was unable to find the size. Feel free to contact me if you can help replace any of the '???' entries.

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. Mac os notepad. 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
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. 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:

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.
Mac Os X 11 Release Date And Price
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.
