Those who still rely on older Mac OS X operating systems, know these still are going strong. There are so many things you can do with past OS X — like Lion, Mavericks or Yosemite — each one of these operates flawlessly. So if you're looking to give your Mac a fresh start with just a classic Mac OS X and nothing else, to clean install Mac OS from USB is the best option for you.

To clean install Mac OS from USB, there are three things you should do. First, you should clean up your Mac from the old baggage — system files that have piled up over time. Once it's all cleaned up, the next you should do is backup your newly cleaned Mac. And finally, after doing a backup, you can clean install OS X of your choice from USB.

• Reset a Mac OS X Mavericks or Mountain Lion Password. If All Else Fails. Finally, if you run into a problem and can't see your way out, one thing to try is to look for an Apple retail store nearby.
• Select Reinstall macOS from the utilities window in macOS Recovery, then click Continue and follow the installer's instructions. Follow these guidelines during installation: Allow installation to complete without putting your Mac to sleep or closing its lid.

We've got the steps outlined below, so let's get to it.

This has been a feature in macOS Recovery since macOS Sierra 10.12.4, and it should reinstall whatever version of the macOS your Mac shipped with, according to Apple.

Step 1: Clean system junk on your current Mac OS X

Whatever OS X you are currently on, system junk and outdated cache files are a potential source for software conflicts. Having cleaned them up, you may discover around 35 GB of newly created space previously taken by junk. What's more, old caches may interfere with your new Mac OS X installation, so this step is pretty essential.

Cleaning can be done either manually or using a dedicated app. If you don't want to spend the next 20 minutes on repetitive clicking and typing, jump right to the automatic solution further down.

The manual way to remove old user caches:

1. Click on a Finder window and choose 'Go to Folder' in the Go menu.
2. Type in ~/Library/Caches and click Enter to go open the folder.
3. Go through each of the folders and remove their contents.

Note: Do not remove the folders themselves, just their insides.

Next off, do the same steps, but now replace..

~/Library/Caches with… /Library/Caches

Automatic solution for system junk cleanup

There are many nice apps that offer a quick Mac clean up. Among those, CleanMyMac 3 is our favorite as it looks most user-friendly of all. It scans your hard drive for old caches, broken apps, and app leftovers so you can remove all unwanted files in a minute or two. After all, a newly installed OS X feels better on a clean computer.

Download CleanMyMac and then follow the steps:

1. Launch CleanMyMac 3.
2. Click Scan.
3. Click Remove.

And you're done. If you want to clean up more junk on your Mac, go through each of the modules located on the left panel of the app. It'll help you clear out gigabytes of junk that you probably didn't even realize were there. Once you've finished the cleanup, head to the next step.

Step 2: Back up your Mac

Before you begin to reinstall Mac OS from USB, you should back up your Mac. Note: If you don't do this step, you will not be able to recover files, nor restore anything if something goes wrong. To back up your Mac:

1. Open an app called Time Machine.
2. Click 'Select Disk.'
3. Select where you wish to save your files (an external drive works best, Apple Time Capsule is a safe bet).
4. Click 'On' on the left-hand side of the screen to turn Time Machine on.
5. On the right, under the name of the storage device, there are three lines that say, 'Oldest backup,' 'Latest backup,' and 'Next backup.' Your backup should be scheduled within the next 5 minutes.
6. Don't want to wait? In the menu bar at the top of your screen, a few icons left of the Date & Time, click on the 'arrow clock' icon and select 'Back Up Now.'

Step 3: Installing Mac OS from USB

You will need 3 essential things:

• The OS X Installer (downloaded from the App Store)
• The backup of your old system
• Startup drive to install OS X on

Once it's all prepared, it's time to clean install OS X. But first, you need to create a bootable drive using a USB containing Mac OS X of your choice. Don't know how? Then read on.

How to create a bootable USB flash drive

1. Connect your Mac to the USB flash drive. It should have at least 12 GB of available storage.

2. Nox on mac os mojave. Open Terminal from the Utilities folder of your Applications folder.

3. Type or paste the following commands in Terminal:

Mavericks:

Yosemite:

El Capitan:

4. Press Return.

5. Type your administrator password and press Return.

6. When prompted, type Y to confirm that you want to erase the volume and press Return. You'll see the progress as the bootable installer is created.

7. Quit Terminal when the process is finished.

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.

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. Make a call to alexa from your mac.

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

Reinstall Mavericks Mac Pro

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.
