macOS 10.15, also known as macOS Catalina, is Mac’s most recent—next-generation—operating system. Apple’s macOS Catalina comes with more to offer compared to its predecessors. A few of this operating system’s features include experience-dedicated apps for podcasts, TV, and music. The best part about this OS is that upgrading is easy and free for all Mac users.

Before getting started, you first have to check if your Mac meets Catalina’s hardware requirements so you can proceed to install it. Here is a list of Mac devices and models compatible with macOS Catalina:

• MacBook 2015 and later
• MacBook Air 2012 or later
• MacBook Pro 2012 or later
• Mac Mini 2012 or later
• iMac 2012 or later
• iMac Pro 2017 or later
• Mac Pro 2013 or later

You can follow these steps to find out the kind of Mac you have:

1. Navigate to the Apple menu.
2. Select About This Mac.
3. The Overview tab will display your Mac from the Overview tab.

Important Information About macOS Catalina

In macOS Catalina, Apple no longer supports any 32-bit apps. Therefore, any apps on your Mac that have not been updated from 32-bit to 64-bit will not function on this OS.

To identify the 32-bit apps on your Mac, follow these steps:

1. On your screen’s top left corner, click on the Apple icon.
2. Select About This Mac.
3. At the bottom of the window, click on the button labeled System Report.
4. On the window’s left side, click on Applications (under the Software section).
5. A list of applications will populate.
6. To find the 64-bitcolumn,move to the right using your cursor. Any 32-bit apps will have No listed in this column.

Before you can upgrade to macOS Catalina, there a few things you have to sort out first, such as:

• Confirmation of your Mac’s compatibility for macOS Catalina.
• Creation of a Time Machine backup.
• Ensuring your Mac has sufficient storage to download, install, and upgrade to macOS Catalina.

Creating a Time Machine Backup

Before upgrading to macOS Catalina, it is crucial to create a Time Machine backup. The reason for the backup is a safety measure for when you find your Mac to be incompatible with the Catalina OS, which means you can erase the upgrade and restore it using the backup you created.

Creating a backup whether upgrading or downgrading your Mac is not only a good idea, but also imperative. Unless you would not mind losing everything, we highly recommend creating a Time Machine backup before upgrading to macOS Catalina. Without the backup, it would take a lot of time to restore your system to its previous OS. You would have to download each program, plug-in, and driver once more.

Follow these steps to format an external hard drive for macOS:

1. Start Disk Utility, which you can find by navigating to Applications > Utilities > Disk Utility.
2. Choose the hard drive device and then click on Erase (if initiated, the process is irreversible)
3. Choose a name for your drive (e.g., My Backup) and select the format: Mac OS Extended (Journaled), then click on Erase.

Follow these steps to create a Time Machine backup drive:

1. Start Time Machine and click on Select Disk.
2. Connect a drive (reformatted or empty).
3. Select the drive you have just connected (e.g., My Backup) and click on Use Disk.
4. Click on the Backup taskbar icon and then select Backup Now.

Downloading macOS Catalina

The upgrade to the macOS Catalina process involves two steps: backup and installation. After you have created a backup, the next step is visiting the App Store to download the macOS installer. Depending on your internet speed, the download may take some time. Upon completing the download, you can install the macOS Catalina app that you can find in your Applications folder.

Storage Space Required for the Download

macOS Catalina needs storage of 12.5GB to 18GB for upgrading. Therefore, if you have insufficient space on your Mac, you can make a backup of some files then delete them from your system to avail the storage required.

Upgrading from Mac OS X Older Versions

Any older versions of Mac OS X 10.7-10.10 have to first upgrade to Mac OS X El Capitan 10.11 version before upgrading to macOS Catalina, which you can download from Apple’s Catalina download page.

To do this, follow these steps:

1. Launch the System Preferences menu, and thenselect Software Update.
2. Click on the Download or Upgrade Now button to begin the download of the Catalina installer.

Installing macOS Catalina

Follow these steps to install macOS Catalina:

1. After completion of the macOS Catalina installation app download, the installer will automatically launch itself. If not, go to your Mac’s Applications folder and double click the Install macOS Catalina app.
2. Follow the instructions that appear on-screen to finish the upgrade and start using the OS.
3. Select an external drive to create an external drive for macOS or an internal drive to upgrade the Mac when prompted.

macOS Catalina’s New Features

Follow these steps to complete installing macOS Catalina’s new features:

1. After macOS Catalina installs, your Mac will restart.
2. After it has started, click on the Apple icon and select About This Mac to view the Catalina OS version.

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

We’ll be repeatedly referring to these Apple OS versions below, so it’s good to know the basic macOS timeline.

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.

Download CleanMyMac for OS 10.9 (free version)

Download CleanMyMac for OS 10.10 - 10.14 (free version)

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:

1. Click the App Store icon.
2. Click Purchases in the top menu.
3. Scroll down to find the preferred OS X version.
4. 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.

1. Start your Mac holding down Command + R.
2. Prepare a clean external drive (at least 10 GB of storage).
3. Within OS X Utilities, choose Reinstall OS X.
4. Select external drive as a source.
5. 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.

1. Boot your Mac from your standard drive.
2. Connect the external drive.
3. 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.
