How to Download and install Windows 10 in one click using Parallels Desktop If you don't have Windows, Parallels Desktop can help you. Jul 08, 2017 By default, your Mac will still boot to macOS. To access Windows, you need to turn off your Mac, then turn it on while holding the Option key. You’ll be asked which drive you’d like to boot from. If you’d like to boot to Windows by default, you set this in recovery mode, or using the Boot Camp Control Panel in Windows. Whether you need to run Windows programs that don’t have Mac versions, or you are making the switch from PC to Mac and need to transfer your data, Parallels Desktop has you covered. Seamless Use Windows side-by-side with macOS (no restarting required) on your MacBook, MacBook Pro, iMac, iMac Pro, Mac mini. May 17, 2017 For Mac users who also need to use a PC at work, home or just with specific applications, there is a solution. Using Boot Camp Assistant, you can install Windows 7 on your Intel-based Mac computer in its own partition. You’ll have a dual-boot system with your Mac OS on one partition and Windows on another. When you install Windows, OS X automatically changes your startup disk to the Windows partition. This way, when you system restarts to finish the installation, it automatically boots into Windows. When your machine is off, press and hold the option key while turning your system on.
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.
Download CleanMyMac for OS 10.4 - 10.8 (free version)
Download CleanMyMac for OS 10.9 (free version)
Download CleanMyMac for OS 10.10 - 10.14 (free version)
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.

Boot Camp for Mac vs virtualization software
If you want to install Windows on your Mac, you have two options. You can either use Mac Boot Camp, a native feature of the macOS operating system, or you can use a third party virtualization program. Both methods have their own pros and cons, so let’s dive in.
Boot Camp is built into the operating system of all Macs. If you go to your Applications > Utilities folder, you’ll see the Boot Camp Assistant app. It makes the separate partition on your hard drive for installing and running Windows. Once Windows is installed in Boot Camp, every time you turn on your Mac, you will be asked to choose the operating system you want to run. This means that in order to switch from macOS to Windows, you need to reboot your computer.
Advantages
- built into your operating system
- easy to use — Boot Camp Assistant guides you through the installation process
- puts less strain on your Mac’s memory and processing power
- completely free (not Windows of course)
- easy to update
Disadvantages
- you need to reboot your computer to switch between the systems
- transferring data between operating systems isn’t easy
Virtualization programs are third-party applications that allow to install a separate operating system on one machine. They run like any other app on your Mac, so you can see the entire Windows desktop within a window on your computer.
Among the most popular virtualization programs are VirtualBox, Parallels, and VMware. Each one has its peculiarities, but we’ll try to sum up what they have in common.
Advantages
- you can run both operating systems at the same time
- easy file integration between systems
Disadvantages
- you need at least 8 GB of RAM for Mac to run smoothly
- virtualization apps are not cheap
- updates are not free
Depending on your specific needs, you can choose the option that works best for you. But we suggest using Boot Camp. It’s a free native feature of your operating system, running directly on your hardware. Therefore, it will be faster than any other method. And below, you’ll find all information on how to run Boot Camp on your Mac.
How to use Boot Camp: Preparing your Mac
1. Check the system requirements
Some versions of Windows require a certain processor and more hard drive space than the others. Therefore, you have to check the documentation that came with your copy of Windows to learn what you need.
You also need to make sure that your Mac is compatible with the version of Windows you want to install. For instance, Windows 10 is supported on these models:
- MacBook (2015 and later)
- MacBook Pro (2012 and later)
- MacBook Air (2012 and later)
- iMac (2012 and later)
- Mac Mini (2012 and later)
2. Clean up your hard drive
You need to have at least 55 GB of free disk space on your startup drive for installing Windows on a Mac. And if you don’t feel like spending the next several hours cleaning your Mac manually, you can use a powerful utility CleanMyMac X to find and remove all the junk from your startup disk.
CleanMyMac has everything to finish the 3-hour task of cleaning your hard drive in less than 5 minutes. It will scan every inch of your system and remove gigabytes of junk in two clicks. By the way, CleanMyMac finds about 75 GB of junk on average — more than enough for a smooth Windows installation.
Here’s how to clean your Mac with CleanMyMac X:
- Download CleanMyMac here.
- Run the app and click Scan.
- Click Run.
That’s it! Gigabytes of junk are gone from your computer forever.
3. Back up your Mac
Finally, you should also perform a backup of your Mac in case something goes wrong. Although, it happens very rarely, it’s always better to back up your important data. There are a few methods of backing up your Mac, so choose the most convenient one for you.
You can make automatic backups with Time Machine — software that comes with your Mac. It backs up all data, so you can recover individual files or your entire system from your backups. You may also store files in iCloud and access them whenever you need. iCloud comes with 5 GB of free storage but you can upgrade it any time. If you have an external storage device, you can copy some files and folders on it.
We do recommend you to back up your Mac before installing Windows as it minimizes the chance of losing important data.
How to Install Windows with Boot Camp
Here’s how to install Boot Camp. The installation can be a little time consuming, but it is by no means difficult. Check out the details below.
Step 1: Get a Windows disk image
First of all, you need to get the Windows disk image (ISO file) from the Microsoft website. Here’s how to download it:
- Visit the Windows 10 disk image download website.
- Go to the Select edition menu and choose Windows 10.
- Click Confirm.
- Choose the language of installation and click Confirm.
- Click 64-bit Download and then click Save.
The ISO file now will be downloaded to your Mac.
Step 2: Open Boot Camp Assistant
Boot Camp Assistant guides you through installing Windows on your Mac. You just have to follow the onscreen instructions. To launch the Boot Camp Assistant, go to Applications > Utilities folder. Click continue and Boot Camp for Mac will automatically locate the ISO file on your system.
Step 3: Create a partition for Windows
When you are done with the Assistant, your Mac restarts to the Windows installer. When you are asked where you want to install Windows, choose the BOOTCAMP partition and click Format.
*Note that this step is only required if you’re using a flash drive or optical drive to install Windows. In other cases, the right partition will be selected and formatted for you automatically.
Step 4: Install Windows
To finish the installation, you have to follow the onscreen instructions. Take a long breath — the next 12 steps may seem like climbing Everest, but it’s much easier than you think. Here’s how to install Windows on a Mac:
- Choose your ISO file and click the Install button.
- Type your Password and click OK. You will see the Windows Setup screen.
- Select your language.
- Click Install Now.
- Type your product key if you have it. Otherwise, click 'I don’t have a product key'.
- Select Windows 10 Pro or Windows Home and then click Next.
- Click Drive 0 Partition X: BOOTCAMP.
- Click Next. Windows 10 will be installed.
- When the Setup screen appears, click either Use Express Settings or Customize Your Installation. We recommend you to choose the Customize button and disable most, if not all of the switches.
- Then you’ll be asked to create an account. Type a username. You can also add a password if you want.
- Click Next.
- Choose whether you want to use the Cortana personal assistant or not. You can disable it by clicking Not Now button.
Windows will boot fully so you can use it normally.
On the Welcome to Boot Camp Installer box, click Next and accept the terms in the license agreement. Then click Install to proceed. When the installer completes, click Finish to reboot your machine.
Step 5: Restart your Mac
By default, your Mac will still boot to macOS. To access Windows, you have to turn your Mac off and then turn it on while holding the Option (Alt) key. You will be asked from which drive you’d like to boot.
Note that while in Windows, the Mac’s Command key functions as the Windows key, while the Option key functions as the Alt key. If you have a Touch Bar, you’ll see a complete set of buttons, similar to the Control Strip in macOS.
How to remove Windows from your Mac
If for some reasons you don’t need Windows anymore, you can permanently remove it from your Mac. Follow these steps:
- Boot into macOS, launch Boot Camp Assistant and click Continue.
- Choose 'Remove Windows 7 or later version' or 'Remove Windows 10 or later version'.
- Click Restore when you see the Restore Disk to a Single Volume option.
The Boot Camp Assistant will automatically remove Windows from your Mac.
Warning: All data, including software and files, stored on the Windows partition will be deleted, so make the backup copies first.
That may seem like a lot of steps, but it doesn’t take all that long to install Windows on a Mac. Now you can enjoy two operating systems and switch between them right when you need. Cheers!
