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.
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
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.

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.

From MorphOS Library
Author: Jacek Piszczek (jacadcaps@poczta.onet.pl)
Quick and unofficial MorphOS & Mac OS X dual boot guide for Apple Mac Mini PowerPC.
Prerequisites
You need a PowerPC Mac Mini, any model will do.
Make sure that you have the OSX Install DVD ready. I used 10.4, but it should bealmost the same for all other versions. With Leopard you might not be able to createreally small partitions, but on the other hand you could try resizing your current OSX partition to make some space for MorphOS. This guide will cover a 10.4 installation on a clean drive.
Download the MorphOS 2.4 + install ISO image and burn it on a CD or DVD.
Hint: burn the ISO as the CD’s image, not as a file on the CD ;)
In case you have an existing OSX 10.3 or 10.4 installation and no access to retailLeopard DVD, you will need a Linux live CD to resize the existing OSX partitionwithout losing your data. Mind that the Disk Utility in Tiger will format all partitions if you make any changes to the partition layout. In this guide I used the Ubuntu 9.04 live CD found at http://cdimage.ubuntu.com/ports/releases/jaunty/release/.
If in doubt, please back up your disk using the Disk Utility’s Restore mode. Making a mirror copy of your hard drive would make it possible for OSX’s Installer to automagically restore all your applications and settings.
Installing OSX from scratch
In case you have an existing OSX installation and do not wish to reinstall, see section 4.
Power the Mini on and insert the OSX Install DVD. Press and hold the c key to forcea CD boot. Run the Disk Utility from the menu once the installer loads. Pick theinternal drive.
Now select the Volume Scheme cycle gadget and select 3 Partitions. Pick the first one and make it 60 MB. The reason for this is that MorphOS actually needs twopartitions: one for the boot files and one for the actual installation.
Hint: to make a partition smaller than 1GB, type 0.1 in Size. This will make thepartitioner switch to MB instead of GB.
At this point it doesn’t matter what file system is selected for the partition, so just ignore whatever Disk Utility preselected for you.
The 3rd partition will be the OSX partition. Give it the size you want, call it OSX and make sure it is using Mac OS Extended (Journaled) in Format. Now click on the‚Partition‘ button and proceed. Quit Disk Utility and proceed with OSX installation as you normally would.
Hint: do click on the ‚Customize‘ button before starting the actual installation. You probably don’t want most of the stuff that’s installed by default.
Installing MorphOS after OSX
Replace the OSX Install DVD with the MorphOS CD / DVD and reboot. Press and hold the c key to make the Mini boot from a CD. Wait for it to load and run the IWizard (hit the Installation button in the welcome window, or go to MorphOSBoot:Tools and double click the IWizard icon).
Proceed with the configuration process until you get to the Storage page.
Make sure you select the manual partitioning mode; we don’t want to erase our freshOSX installation. After clicking next you will see the partitioner view.
Select the first partition and make sure the Filesystem field is set to HFS, and the name is changed to DH0.
Note: do NOT remove the 128MB padding partitions. Mac OSX expects them to bethere!
Now select the 1st big partition: this is the partition to install MorphOS on.
Change the Name to DH1, set the Filesystem to SFS and enable the Boot (A/UX)flag.
You may also want to rename the OSX partition so that it shows up as DH2 underMorphOS.
Now hit the Save button below the hard drive icon next to the partitions list. Do NOT click on the Next button!
Click on the MorphOSBoot CD icon on the desktop and go to Tools. Run theMounter application (double-click).
Select ide.device unit 0 and the DH0 partition. Click on the Filesystem cycle gadgetand select MAC HFS (!). Now click the Mount button.
Note: MorphOS´ installer expects a HFS formatted partition called Boot and willstore boot files on it. It is absolutely necessary that you create the partition and name it ‘Boot’ and nothing else. You cannot use a HFS+ partition since MorphOS doesn’t have write support for HFS+. This would make the installer fail.
If the DH1 partition has ‘–‘ in the Mounted As column, select it and hit Mount(Filesystem must be either Autodetect or MorphOS SFS).
Now click on the desktop and click with the right mouse button over the screen’s topbar (in case you’re using some silly 1-button mouse, right command (Apple) key +right alt key simulate a right mouse click under MorphOS, you may also open themenu with right command + space and navigate it with arrows). Select Format fromthe Utilities menu.
Select DH0 and name it Boot (yes, this REALLY is required, you have to name itBoot or MorphOS will fail to install). Press the Quick Format button. Now selectDH1 and name it however you like, for example System.
Now go back to the IWizard application (in case you don’t know, double-clicking ona window brings it to front in MorphOS, unlike a single click in OSX). Click on theNext button. If all went fine you will see this:
Assuming everything is correctly formatted and mounted, the installer picks the drive to install (DH1) automatically. Now just click Install and wait until it’s done copying.
Preparing an existing OSX installation for MorphOS
As mentioned in the Prerequisites section, in case you have an existing OSXinstallation, you will have to resize its partition to make some room for MorphOS.Since not everybody has retail Leopard DVD, I will use Ubuntu to explain how to dothis.
Note: please read sections 2 and 3 before trying this out, some explanations available there were omitted in sections 4 and 5.
Power the Mini on and insert the Ubuntu Live CD. Press and hold the c key to force aCD boot. Now run the Partition Editor from the System -> Administration menu.
Select the OSX hfs+ partition and click on Resize/Move. Resize the partition byclicking and dragging on its right edge. Do NOT move the partition from its left edge.
You MUST disable the Round to cylinders checkbox, or GParted will try to move theOSX partition. Make sure the Free Space Preceding (MiB) field stays at 128. Youshould leave at least 1GB of free space following the OSX partition. I’d recommendaround 20GB. Now click on the Resize/Move button to apply your changes.
Click on the gray space called unallocated and click New. Set the New Size (MiB)field to 64 and the File System to hfs. Make sure the Round to cylinders checkbox isdisabled. Click the Add button.
Morfosi Mac Os X
Select the unallocated space again, change the File System to unformatted (we willchange it from MorphOS later), disable the Round to cylinders checkbox and pressAdd.
Click the Apply button to apply our partition table changes. It will take some time to resize the partition, depending on the used space. Make sure you’ve backed up your data because a sudden power outage will most likely make your data hard /impossible to recover.

Once the process completes, reboot into OSX to see if all went OK.
Installing MorphOS next to an existing OSX installation
Make sure you followed all steps in section 4. Replace the Ubuntu CD with theMorphOS CD and reboot. Press and hold the c key to make the Mini boot from a CD.Wait for it to load and run the IWizard (hit the Installation button in the welcomewindow, or go to MorphOSBoot:Tools and double click the IWizard icon).
Proceed with the configuration process until you get to the Storage page.
Make sure you select the manual partitioning mode; we don’t want to erase ourexisting OSX installation. After clicking next you will see the partitioner view. Select the OSX HFS partition and make sure the Boot (A/UX) flag is unset. Name thispartition DH0.
Note: the partition’s Filesystem is always HFS, even if it’s formatted with HFS+, this is the reason why we have to specify the FS type manually when mounting it later.
Edit the 64MB HFS partition now. Name it DH1 and make sure the Boot (A/UX) flagis turned off. The Mount (A/UX) flag can be ignored.
Last will be the partition for the MorphOS installation. Name it DH2 and make surethe Boot (A/UX) and Mount (A/UX) flags are turned ON. Change the Filesystem toSFS.
Save the changes by clicking on the Save button below the hard drive icon. Do notpress Next yet!
Click on the MorphOSBoot CD icon on the desktop and go to Tools. Run theMounter application (double-click).
Select ide.device unit 0 and the DH1 partition. Click on the Filesystem cycle gadgetand select MAC HFS (!). Now click the Mount button.
If the DH2 partition has ‘–‘ in the Mounted As column, select it and hit Mount(Filesystem must be either Autodetect or MorphOS SFS).
Now click on the desktop and click with the right mouse button over the screen’s topbar (in case you’re using some silly 1-button mouse, right command (Apple) key +right alt key simulate a right mouse click under MorphOS, you may also open themenu with right command + space and navigate it with arrows). Select Format fromthe Utilities menu.
Select DH1 and name it Boot (yes, this REALLY is required, you have to name itBoot or MorphOS will fail to install). Press the Quick Format button. Now selectDH2 and name it however you like, for example System.
Note: If the HFS partition is already formatted, Quick Format it anyway.
Now go back to the IWizard. Click on the Next button. Assuming everything iscorrectly formatted and mounted, the installer picks the drive to install (DH2)automatically. Now just click Install and wait until it’s done copying.
Trying it out, changing the default system
After a successful installation you may start MorphOS from the HD. Eject the CD byright clicking on its icon and selecting Eject. Reboot MorphOS either by selectingShut Down… from the Ambient menu, or by pressing control + left command + rightcommand keys.
Note: if you don’t eject the CD, MorphOS will try to boot from it again! It will load the boot.img from the hard drive, but all other files from the CD even if the c key wasn’t pressed
By default, the Mac Mini will boot OSX. To boot MorphOS, press and hold the altkey – this will bring up the OpenFirmware’s graphical boot menu. Select the partition with a butterfly icon and you will boot into MorphOS.
In order to boot MorphOS by default, one must change the OpenFirmware settings.To get to the firmware prompt: reboot and press and hold the command + option + o+ f keys until you see the OF screen.
To determine the partition number of the HFS boot partition type the following:
where x should be a number from 3 to n, depending on partition layout. If you seeboot.img and bootinfo.txt files being listed, this is the correct one. Now type:
replacing x with the partition number you just found.
It’s possible to slightly increase the booting speed by making OF skip the networkbooting initialization. This is done with:
Now save the changes and reboot by typing:
… and the Mini will now boot MorphOS by default. To boot OSX just hold the altkey and select it from the menu.
Have fun and don’t forget to register MorphOS :)
