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.
7 Zip Mac Os X
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:
- 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.
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
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.
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.

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. Below are a few more links you may find interesting.

What is Easy 7-Zip?
Briefly speaking, Easy 7-Zip is an easy-to-use version of 7-Zip. Originally, Easy 7-Zip was built based on 7-Zip 9.20. I kept all features of 7-Zip and added a few useful features that makes the software more user-friendly. Recently, 7-Zip upgraded to 16.04. So, I moved codes to the version.
Free Download 7 Zip Software
7-Zip is a free and great file decompression and compression software that handles 7z, AR, ARJ, BZIP2, CAB, CHM, CPIO, CramFS, DEB, DMG, EXT, FAT, GPT, GZIP, HFS, IHEX, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, QCOW2, RAR, RAR5, RPM, SquashFS, TAR, UDF, UEFI, VDI, VHD, VMDK, WIM, XAR, XZ, Z, ZIP, and ZIPX archives. 7-Zip was developed by Igor Pavlov.
Why did I make Easy 7-Zip?
7-Zip is a great file archive freeware. I love the software very much. Thank Igor Pavlov! However, when I used the 7-Zip frequently, I thought the software could be better. So, I downloaded source code of 7-Zip and, studied and modified the code in my leisure time, and made the Easy 7-Zip. I hope the Easy 7-Zip is useful for everybody.
What features were added to Easy 7-Zip?
1. Adds icons to context menu
* Note: just for 7-Zip 9.20. The latest version (16.04) of 7-Zip has added the feature.
7 Zip Download
When I was using WinZip or WinRAR, I can easily find menu items of WinZip or WinRAR in context menu of Explorer. As there are icons with the menu items. However, 7-Zip doesn't offer the feature. So I decided to add the feature first. When it's done, the context menu looks like the following screen shots.

2. Adds options to Extract dialog
![7 zip free download 7 zip free download](/uploads/1/3/4/4/134462302/568008464.jpg)
I added 4 features to the extract dialog in 7-Zip File Manager.
- Button 'Open': Easy 7-Zip will open output folder when clicking on the button. So you can easily view files or directories in the folder by a click.
- Button 'Filename': When the button is clicked, Easy 7-Zip adds file name to end of output folder so that the program will create folder of file name and extract files to the folder. For example, file name is sample.7z, output folder is D:Output, when clicking the button, the output folder will be D:Outputsample, and all files will be outputted to the folder.
- Show free and total space of output drive. It's useful for large file.
- Options 'After extraction completes successfully':
- Open output folder: If the option is checked, Easy 7-Zip opens output folder after extraction. So that you can locate to the output files easily.
- Delete source archive: Delete source archive after extraction completes successfully. If any errors happen while extracting, for example, wrong password, the Easy 7-Zip won't delete the source archive.
- Close 7-Zip: Close 7-Zip after extraction.
Extract dialog of context menu was changed to something like screen shot below.

3. Keeps same output folder history

7-Zip uses separated output folder history for extract dialog of 7-Zip File Manager and context menu. However, we probably use either way to extract file and we can't find output folder history of another. I made Easy 7-Zip uses same output folder history for the both extract dialogs and extends number of output folder history up to 30.

4. Minimizes to system tray when clicking 'Background' on progress dialog
It's something like the 7-Zip does nothing when clicking on 'Background' in original 7-Zip. Actually the 7-Zip sets progress priority of itself to idle. So user could do other things without performance loss on the same computer. However, it could be better if the 7-Zip minizes to system tray when background working. I got the feature possible in Easy 7-Zip. The program shows progress in system tray as well.
I also added percent of progress to the dialog, although the percent shows in title of the dialog. As I don't get used to see the percent in dialog title.
If you can't find the icon in system tray area, it probably was hidden by Windows. Please click a little triangle in system tray area and, you will get the icon.
5. Makes a new installation file
I made a package of Easy 7-Zip that contains both x86 (32-bit) and x64 (64-bit) editions. In other word, the package installs x86 (32-bit) edition of Easy 7-Zip on 32-bit Windows and x64 (64-bit) edition on 64-bit Windows automatically. The package also allows user to associate 7-Zip with file extensions including 001, 7z, arj, bz2, bzip2, cab, cpio, deb, dmg, fat, gz, gzip, hfs, iso, lha, lzh, lzma, ntfs, rar, rpm, squashfs, swm, tar, taz, tbz2, tbz, tgz, tpz, txz, vhd, wim, xar, xz, z, and zip.
6. Other user interface improvement
Why is Easy 7-Zip larger than 7-Zip?
7 Zip Mac Os
- Package of Easy 7-Zip contains both x86 (32-bit) and x64 (64-bit) editions of EXE and DLL files.
- 7-Zip was compiled with MS Visual C++ 6.0. However, I compiled the Easy 7-Zip with MS Visual C++ 2008. The later generates larger file than the former. And, I optimized Easy 7-Zip with maximize speed instead of minimize size and, enabled whole program optimization that will generate more efficient code.
