How to get old versions of macOS

If your Mac isn’t compatible with the latest macOS, you might still be able to upgrade to an earlier macOS, such as macOS Catalina, Mojave, High Sierra, Sierra, or El Capitan.

To get the latest features and maintain the security, stability, compatibility, and performance of your Mac, it’s important to keep your software up to date. Apple recommends that you always use the latest macOS that is compatible with your Mac.

Check compatibility

The version of macOS that came with your Mac is the earliest version it can use. For example, if your Mac came with macOS Big Sur, it will not accept installation of macOS Catalina or earlier.

If a macOS can’t be used on your Mac, the App Store or installer will let you know. For example, it might say that it’s not compatible with this device or is too old to be opened on this version of macOS. To confirm compatibility before downloading, check the minimum hardware requirements:

Download macOS using Safari on your Mac

Safari uses these links to find the old installers in the App Store. After downloading from the App Store, the installer opens automatically.

• macOS Catalina 10.15 can upgrade Mojave, High Sierra, Sierra, El Capitan, Yosemite, Mavericks
• macOS Mojave 10.14 can upgrade High Sierra, Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion
• macOS High Sierra 10.13 can upgrade Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion

Safari downloads the following older installers as a disk image named InstallOS.dmg or InstallMacOSX.dmg. Open the disk image, then open the .pkg installer inside the disk image. It installs an app named Install [ Version Name ]. Open that app from your Applications folder to begin installing the operating system.

• macOS Sierra 10.12 can upgrade El Capitan, Yosemite, Mavericks, Mountain Lion, or Lion
• OS X El Capitan 10.11 can upgrade Yosemite, Mavericks, Mountain Lion, Lion, or Snow Leopard
• OS X Yosemite 10.10can upgrade Mavericks, Mountain Lion, Lion, or Snow Leopard

How to create a bootable installer for macOS

You can use an external drive or secondary volume as a startup disk from which to install the Mac operating system.

These advanced steps are primarily for system administrators and others who are familiar with the command line. You don’t need a bootable installer to upgrade macOS or reinstall macOS, but it can be useful when you want to install on multiple computers without downloading the installer each time.

What you need to create a bootable installer

• A USB flash drive or other secondary volume formatted as Mac OS Extended, with at least 14GB of available storage
• A downloaded installer for macOS Big Sur, Catalina, Mojave, High Sierra, or El Capitan

Download macOS

• Download: macOS Big Sur, macOS Catalina, macOS Mojave, or macOS High Sierra
  These download to your Applications folder as an app named Install macOS [ version name ]. If the installer opens after downloading, quit it without continuing installation. To get the correct installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.
• Download: OS X El Capitan
  This downloads as a disk image named InstallMacOSX.dmg. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. You will create the bootable installer from this app, not from the disk image or .pkg installer.

Use the ‘createinstallmedia’ command in Terminal

1. Connect the USB flash drive or other volume that you’re using for the bootable installer.
2. Open Terminal, which is in the Utilities folder of your Applications folder.
3. Type or paste one of the following commands in Terminal. These assume that the installer is in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you’re using. If it has a different name, replace MyVolume in these commands with the name of your volume.

Big Sur:*

Catalina:*

Mojave:*

High Sierra:*

El Capitan:

* If your Mac is using macOS Sierra or earlier, include the —applicationpath argument and installer path, similar to the way this is done in the command for El Capitan.

After typing the command:

1. Press Return to enter the command.
2. When prompted, type your administrator password and press Return again. Terminal doesn’t show any characters as you type your password.
3. When prompted, type Y to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the volume is erased.
4. After the volume is erased, you may see an alert that Terminal would like to access files on a removable volume. Click OK to allow the copy to proceed.
5. When Terminal says that it’s done, the volume will have the same name as the installer you downloaded, such as Install macOS Big Sur. You can now quit Terminal and eject the volume.

View and restore past versions of documents on Mac

Many apps automatically save versions of documents as you work on them. At any time, you can browse through document versions and go back to an older version. You can also explicitly save a version.

A version is saved automatically every hour, or more frequently when you’re making many changes. A version is also saved when you open, save, duplicate, lock, rename or revert a document.

Browse, restore, duplicate and delete versions

On your Mac, open the document, then choose File > Revert To > Browse All Versions.

Click tick marks along the timeline to browse versions.

Display the version you want, then do one of the following:

Restore your document to this version: Click Restore.

Duplicate this version in a new document: Press and hold the Option key, then click Restore a Copy.

Delete this version: Move the pointer to the top of the screen to show the menu bar, then choose File > Revert To > Delete This Version.

Leave your document as is: Click Done.

Explicitly save a version

On your Mac, open the document, then choose File > Save.

To save the document using a different filename, location, or format, press and hold the Option key, then choose File > Save As.

Revert a document to the last opened version

On your Mac, open the document, choose File > Revert To, then choose Last Opened, Last Saved or Previous Save.

How to Browse & Revert to Prior Versions of a File in Mac OS X

All modern releases of Mac OS X include a powerful built-in version control system that allows a user to revert to any previously saved version of a file or document, assuming the app supports the version revision feature. This ability is often overlooked by Mac users, but it can be a real lifesaver when you’ve caught yourself having modified a file inadvertently, or discovered that recent changes to a document should be undone. In some sense, you can think of this feature like a file-level “Undo” feature included in OS X, and it works fairly similar to the Time Machine backup browser on the Mac.

We’re going to demonstrate the Revert To feature with version revision in the TextEdit app of OS X, but you’ll find the feature in many other Mac apps as well, like Pages, Keynote, and Numbers. Keep in mind this will only work for a Mac file that has been generated locally and thus is using the Versions feature cache, files that are sent to you or downloaded from elsewhere will (almost certainly) not contain the revision control data necessary to revert to a prior version of that document.

Access the Version Browser & Restore to a Prior Version of a Document in Mac Apps

1. Open the document you wish to browse revisions for and revert to a prior version of
2. Pull down the “File” menu in that application and go to the “Revert To” menu, then choose “Browse All Versions” to open the version browser feature

Navigate between the different saved versions of the file using the arrows on the right-side of the version browser, you can also use the arrow keys on the keyboard, or the scroll wheel on a mouse, or scroll gesture on a trackpad

When you’ve found the version you wish to revert the document to, click on the “Restore” button

Once you choose “Restore” the chosen previously saved version of that file will open immediately, reverting from the other version of the file to that selected revision.

In case you were wondering, yes you can also go backwards again by returning to the Revert To menu, or, if you want you can instantly revert to most recently saved version by choosing that from the same Revert To menu as well.

This feature depends on specific applications supporting it, though it has been around in OS X from quite some time, including El Capitan, Yosemite, Mavericks, Mountain Lion, and Lion, not all developers have included version support in their applications yet. Nonetheless, it’s always worth a try, certainly before you dig out the Time Machine backup drive, though Time Machine is still going to be necessary for reverting to prior versions of files when the origin application does not support Versions.

Finally, it’s important to point out that if you disabled auto-save or turned off Versions for some reason or another, you will not gain the full effect of this feature. Additionally, if you happened to have cleared the versions history or auto-saved caches for the files, there will also be no version control for that particular file, or any others where the caches were removed from the Mac – this is the same reason why you can’t perform version reverting on files that are not created on your own Mac, the cache and version control files simply do not exist in that case.

Ratings and Reviews

Needs internet

Tried to use it on the train and found unless I had an internet connection the UI refused to load. Since there are other ways to edit attributes I am removing this application.

When you need it, it’s wonderful

This app can be a lifesaver. If you need to edit file properties on one or a bunch of files this app will do exactly that. The user interface does a few things in non apple standard way so I give it 4* not 5. Here is an example of my need. Somehow mac OS managed to change the creation date on several hundred files in a project and them equal to modification date. That made sorting files ugly for me. But the EXIF data and the GPS data were not corrupted. I could set the creation dates on all the files to be the EXIF Digitized Date (the REAL creation date) as a fast batch job. WHEW! What a lifesaver!

I found several other uses. If you still remember your Unix command lines, and love scripting, you can get by without this tool. Maybe. If you are a mere mortal this app might be a Godsend. You might have to actually read the manual and still play around a bit. The hover descriptions are pretty good even if the icons are not always obvious.

Hard to use, but helpful.

I’m a professional photographer and I messed up by setting both of my cameras to the same time in terms of numbers, but one was AM and the other was PM. This meant the entire day was out of order. Thankfully after some quick tinkering in this app it was as if the problem never happened. Only reason it’s 4 instead of 5 stars is that the UI is really difficult to use.

App Privacy

The developer, Lei Feng , has not provided details about its privacy practices and handling of data to Apple.

No Details Provided

The developer will be required to provide privacy details when they submit their next app update.
