How to Install Old OS X on Your Mac

Although you might think that going back to the old macOS is not possible by looking at the App Store Updates tab, it’s actually quite easy to do. In this article, we’ll take you through everything you need to download and install an old OS X on your Mac.

Prepare your Mac first

Make sure you are ready to downgrade your operating system by checking in with what version of OS X you already have and ensuring you have enough hard drive room to download the older version. Clicking the apple in the top left corner of your desktop and selecting About This Mac will allow you to see what OS X version you are currently running. Tabbing over to Storage will let you know how much disk space you have available. You’ll need around around eight gigabytes free depending on which macOS you downgrade to.

Even if you do have enough space, it’s a good idea to clean your computer before installing the desired operating system. You can, of course, do so manually by deleting unused files and uninstalling old software to free up disk space. Depending on how tidy you are, this might take quite a bit of time.

To make things easy, use a specialized app like CleanMyMac, which will quickly free up space by detecting unused apps and large files, and offering to completely delete them, with all their hidden corresponding files, in one quick click.

Optimizing your Mac with CleanMyMac is effortless:

  1. Launch CleanMyMac
  2. Select the Smart Scan tab and click Scan
  3. Review Details to see the list of suggested optimizations
  4. Click Clean

To uninstall certain apps, find the Uninstaller tab and select the apps you haven’t been using for a while.

The only solution that will free up disk space, uninstall 32-bit apps, and solve tons of problems to prepare your Mac for a new macOS.

The final preparation step is to make sure you back up all your important files to cloud storage or an external drive. A proper backup app like Get Backup Pro can save you a lot of headache here.

To create a new backup with Get Backup Pro:

  1. Connect your external hard drive
  2. Click the plus icon in the bottom left corner
  3. Type in the name for your backup
  4. Choose your external drive as a destination
  5. Adjust all the settings according to your preference and click OK
  6. Tap the play button once you ready to perform the backup

Downgrading to previous operating systems on Mac gets easier. To put it shortly, Setapp has your back here.

Download the OS X you want

Once you have space on your computer, figure out what version of OS X you would like to install. You can see all previous versions of OS X your Mac has installed by opening up the App Store and clicking the icon in Applications. Tab to the Purchase page of the menu and scroll down to find the line for previous operating systems. Clicking the install button of the macOS you want will begin downloading the file.

What if I can’t find the version I want in the app store?

If your goal is to download a version of macOS that you have not already used, or, that was not available as an update from the App Store after you bought your Mac, you may need to purchase it. The earliest versions, OS X Lion and OS X Mountain Lion are available on the Apple Store’s website and arrive to you via email for download. OS X Snow Leopard ships as a boxed version and requires a disk drive to install.

It could be helpful to know where you sit on the timeline of macOS X updates. Below is a chronological list of all the updates beginning with the most recent update, High Sierra, released in 2017:

  • OS X High Sierra 10.13
  • OS X Sierra 10.12
  • OS X ElCapitan 10.11
  • OS X Yosemite 10.10
  • OS X Mavericks 10.9
  • OS X Mountain Lion 10.8
  • OS X Lion 10.7, released in 2011

Visiting the Apple Support’s Downloads page makes it easy to search for any version of macOS you might need, and most are available for free. Downloads for previous versions of OS X are linked below and include:

Alternative sources for downloading macOS

Older Version Yahoo Mail

If you can’t find the version you want from Apple, ask a friend who is running the macOS you’re looking for to make a copy of the installer file for you. Downloading a .dmg file from a torrent site may seem a quick solution, but it means risking your security. Alternatively, you could hit up your nearest Apple Store. They will likely have image files of all the different versions of the software and help you install it right there as well.

Install the macOS


If you download the file from the App Store, the installer will start immediately. Follow the prompts and be prepared to restart your computer. If you acquire the installer from another source, just downloading the file will not install the OS X right away on your Mac, you’ll need to find the file in your Downloads or Applications folder, then open and run the installer from the downloaded file.

I can’t download an old version of Mac OS X

A downgrade is different than an upgrade. When you try to downgrade macOS, the installer may not launch right away depending on which versions of macOS you are moving between. If your installer does not launch, or you get an error message that reads: “This copy of the ‘Install OS X’ application is too old to be opened on this version of OS X,” you’ll need to use a bootable USB or external drive to work around this problem.

Get a bootable drive with OS X

Creating a bootable USB or a bootable drive is not complicated. You’ll need an external drive with enough space to hold your desired OS X on it and a basic familiarity with Terminal, Apple’s command line interface.

If you’re uncomfortable using Terminal to execute basic commands, use an app like Disk Drill to help create a boot drive. Whether you use Terminal or Disk Drill, our guide on creating a bootable installer will walk you through all the necessary steps.

How To Download Mac Os

Remove the old OS X

Once your drive is prepared with your bootable version of OS X, erase the unwanted version. After you restart your computer, press and hold Command + R. When you enter the macOS Utilities screen, navigate to Disk Utility, click continue, and find your Startup Disk. Tab to the Erase page and name the file you want erased (e.g. macOS High Sierra). Then select Mac OS Extended (Journaled) from the dropdown menu. Hit Erase and quit out of Disk Utility. This will return you to the OS X Utilities selector.

Install the bootable version of OS X

If you used Disk Drill for creating your bootable drive, a window will prompt your actions for using the install disk you made. But if you created your own using Terminal, use OS X Utilities Selector and find Reinstall OS X. Find and select your install disk with your bootable version of your preferred macOS, and click continue through to the license agreement. Once you agree, you should be prompted by the installer. Once the installation is completed, your computer should restart. If it does not restart itself, make sure you restart it normally. The downgrade should be complete!

As you can see, downgrading your OS X is not as dreadful as you might think, especially if you use helper apps like CleanMyMac, Get Backup Pro, and Disk Drill — all of which are available for a free trial on Setapp. So downgrade away!

Download Old Macos Installers

Have an old Mac and want to reinstall MacOS? Maybe you want to back up your Mac to the first version of Mask that you just installed?

Although the process is straightforward, it is not easy to get your hands on old Macos publications.

Before you begin

It is important to understand that not all versions of MacOS (or Mac OS X) work with all hardware configurations. It is common for newer Mac releases to often abandon older hardware support, but the same is true for newer Mac models and older software.

For example, you can’t install any version of MacOS before Big Pig (released in 2020) on Macs with Apple Silicon chips, including the M1. Older versions were written for Intel chips, which use the x86_64 instruction set, while Apple’s new Silicon chips use the ARM instruction set.

The “early” supported version of your Mac is the MacOS that came with it. If you’re not sure what your Mac brought, go to Apple Support and find the exact model. You can find out which Mac you have by clicking on the Apple logo in the upper left corner and selecting “About this Mac” to see the release name and year.

If you agree, you can install newer versions of Mac as your Mac does with tools like Patched Pig. After trying, you may come to the conclusion that new releases on your hardware perform poorly, at which point, you have to step back.

This guide can help you get back to almost any version of MacOS. If you decide to try a newer version of MacOS and rely on a time machine for your backup, support backup with a time machine until you are sure you want to stay there.

Older versions of Mac OS may have difficulty restoring time machine backups with later releases. For example, trying to restore a time machine backup built in Big Pig (released in 2020) in Max Catalina (released in 2019) can be difficult.

You can get it using a third-party backup tool like Carbon Copy Cloner or ChronoSync. As a last resort, you can manually back up your important documents, libraries, and any external drive. We recommend that you test any experimental Mac OS installations before performing.

Where to download older version of MacOS

You can download links from most older versions of Max or from Apple’s website using the Mac App Store. Unfortunately, the Apple Mac App Store does not index entries so you can find them in the app. To get them, you’ll need to follow the direct links we’ve listed below.

Note: If you’re having trouble working these links, first make sure you’re using Safari, then close the Mac App Store and try clicking the link again.

Links to the Mac App Store for downloading old MacOS

Once any of these downloads are complete do not do that Open the installer to begin the installation. Leave the installation app in your Applications folder.

Direct disk image links for older Mac OS downloads

Once any of these downloads are complete, mount the .dmg file and run the .pkg installer inside you. This will put an installation app in your Applications folder, which you can leave there.

Also get older versions of OS X.

If you have a valid Apple Developer account, you will be able to download the Apple version / download from the developer. Non-developers can purchase OS X Mountain Lion ($ 19.99) and OS X Lion (19 19.99) directly from Apple. Apple will email you an unlock code, which you can return to the Mac App Store.

Older copies of Lion, Mountain Lion and even Snow Leopard may be for sale on sites like eBay.

Some websites may offer older versions of OS X for download, but we recommend avoiding them. First, the installer may contain malware. Second, there are legal concerns: OS X is still copyrighted software. Even if you own the license, you may not be able to download it legally within your jurisdiction. If you can do this, you can’t legally use BitTorrent to download it, because your BitTorrent client uploads parts of OS X to other people during the download process. Will do

Reinstalling the old version of Mac OS

You need to make a bootable USB stick to install older versions of MacBoos. You can use this drive multiple times on different machines, throw it in the drawer next time, or delete it when it’s finished and when it’s time to reinstall.

Prepare your USB drive

Apple has proposed a USB drive in the form of Mac OS Extended, with 14 GB of free space for the latest version of Mac OS. We’ve used Catalina in the past and 8GB drives to install before, so your mileage may vary.

To format your drive, connect it to your Mac, and then launch Disk Utility (you can do this using Spotlight or by searching for the app in your Applications> Utilities folder.) Drive in the sidebar. Search, click on it, and then click “Delete” and name it. In the drop-down box, select “Mac OS Enhanced (Traveled)”, and then click “Delete” to begin the process.

Make the bootable USB in the terminal

We’ll use the terminal to create a USB drive, so launch it via Spotlight or find the app in your Applications> Utilities folder. You can use the same command to create your installation medium, but it varies depending on which version of MacOS you are trying to install.

This assumes that you are installing Big Pig, that your drive is labeled “Mycos_Installer”, and that you have the corresponding MacOS installer in your Applications folder.

sudo /Applications/Install macOS Big Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/macos_installer

You can modify different parts of this command according to your own circumstances, including the name of the central installer. Be aware that you have to retreat before any vacancy. For example, “Install Mac OCS High Server – App” will become Install macOS High Sierra.app In this context.

Here’s another example of how to install a MacOS High Server USB drive on a drive called “Mac OS Installer”.

sudo /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MacOS Installer

You can drive ls If you need to check the label, order to enter all the volumes attached to it, including your USB installation medium.

Once you press Enter, you’ll need to enter your own admin password to confirm the command, and then hit “Y” on your keyboard to confirm that you have the contents of the USB drive. OK with overwriting.

Install Mac OS from scratch

Once your installation files have been copied, it’s time to install MacOS from scratch. To make sure everything goes smoothly, we will take the extra step of deleting your existing partition before installing the Mac.

How to install older version of macos

Insert your USB drive first and turn off your make-up. The next step will be different depending on what type of Mac you have (here’s how to tell).

  • Apple silicon (M1 chip and newer): Press and hold the power button until you see the Startup Options window, and then click on the USB volume you created earlier and press Continue.
  • Intel powered Mac: As soon as you turn on your make-up, press and hold the option (alt). Release when you see the list of bootable volumes, select the USB stick you created, and click the up arrow.

Once the MacOS is loaded (you may need to select a language first), click Utilities> Disk Utility. Select your drive (usually labeled “Macintosh HD”) in the sidebar, and then click “Delete”.


Warning: The next step will be to erase the contents of your Mac’s system volume, so make sure you’ve backed up any data you don’t want to lose.

If you are installing MacOS Sierra or later, select “APFS”. Otherwise, you’ll need to format it into “Mac OS Extended” for AlCaptain and earlier. When you are sure of your decision, click “Delete” and confirm.

Finally, leave the Disk Utility and select “Install MacOS” or “Install MacOS” (or MacOSX, for older versions) from the MacOS Utilities window. Follow the rest of the prompts to finish the installation.
