Make sure you've reviewed all of these!
We've already covered how to operate a Mac OS Times on your Hackintósh, but that guide won't perform you very much good if you haven't set up Mac Operating-system Back button on your PC however. If you require help deciding whether to make that leap of faith, after that you can try out installing Mac OS Back button Snowfall Leopard on Virtualbox, rather. Virtualbox is a virtualization collection that works for Home windows- installing Mac OS X on a digital machine in Home windows before performing it on your actual computer is definitely great exercise, and it gives you a opportunity to determine whether you'chemical actually prefer OS A over Home windows. Read through past the separate for a full tutorial. Take note: The using guide is for installing Mac Operating-system X Snow Leopard only, because it uses the same method that I use for my.
For this virtual device, we're also heading to make use of Virtualbox, which is certainly a free of charge and open-source virtualization suite. Installing Operating-system Times with Virtualbox on Windows is even more hard than doing it with VMWare Blend in Operating-system X, because Windows virtualization applications do not 'officially' support Mac OS A. You will not really be capable to allow full images assistance, for example. This guide should only be used as a proof of concept. Computer Needs You need a personal computer with Windows to operate Mac OSX on Windows (of training course).
You will need at least 4 GB of RAM and a duaI-core (two primary) processor or better. Personally, the pc I has been making use of for this acquired a 4-primary processor and 12 GB Memory, which is way more than enough. You also require about 10 GB of untouched hard push space. Right click on 'My Personal computer' on your desktop computer and click 'Attributes' to check out the stats on your computer. If it doesn't straight tell you how several cores your processor chip has, look up your processor design on Wikipedia or Search engines. You also to notice keep in mind whether your processor is definitely 'Intel' or 'AMD'. This guidebook does not really cover AMD processors, as they make Mac Operating-system X even more hard to arranged up.
General Needs In inclusion to a good computer that uses an Intel processor, you need these subsequent three points to operate Mac OS X on Windows.: This virtualization package is free (unlike VMWare), ánd though it doésn't offer official assistance for Mac pc OS X, it works well good enough.: You require tonymacx86't boot CD to boot the Mac OS Times installer, and Multibeast to enable Virtualbox to shoe OS X without iBoot afterwards on. Formally, any shoe Compact disc for Macintosh OS X will work, and you don't want Multibeast to set up (the primary componen of Easybéast), but we'Il use tonymacx86's equipment for the sake of convenience. As normal, you have got to sign-up on tonymacx86.com to download these equipment. ($20): The method utilized by this manual needs the retail DVD for Mac OS A Snow Leopard. Action 1: Prep Download, set up it, and open it up. Also, if you would like to end up being capable to view USB products from your Mac OS A Snowfall Leopard digital machine, download the and operate it before going to Step 2.
You furthermore require to download the.iso document for. Step 2: Create a brand-new virtual machine Virtualbox allows you operate Mac OSX within Home windows by developing a digital device, which is certainly a system that simulates a normal pc. To generate a digital machine, open up up Virtualbox and click 'New' on the top left. Provide your fresh virtual device a name, and choose 'Macintosh OS Times' for the OS Type.
I suggest assigning at least 2 GB of Ram memory to the virtual device, but you can designate mainly because little as 1024 MB of RAM. Every period you change on Mac pc OS A, that Ram memory that you give here will become used to run the virtual device. The RAM will end up being given back to your normal pc after you turn Virtualbox off. You'll require to generate a fresh hard disc for the digital machine. Virtualbox will ask you what kind of drive you want to make: VDI, VDMK, ór VHD.
VDI can be the unique file format for Virtualbox, while VDMK is definitely the structure utilized by VMWare. lf you're considering getting a copy of VMWare, you might need to select VDMK. In any other case, just select VDI. I recommend generating a dynamically growing drive; the just other option, fixed-size storage space, will eat up your difficult drive.
Phase 3: Provide your brand-new virtual device an operating program. Your virtual device will right now be developed. But don't halt now-you nevertheless need to alter a several configurations before your device will really work. Your brand-new virtual device will display up on the still left column of the Virtualbox begin page. Select your Mac pc OS Times virtual machine (single-click) from the major web page of Virtualbox, and open up up the virtual machine settings. Once the settings open up, go to 'System' and uncheck thé 'Enable EFI' box. This will be by far the nearly all important single setting that you will require to modify.
EFI, which stands for Extended Firmware Interface, can be a feature that helps operating techniques begin up. However, Mac OSX needs 'speshul' EFI, só the EFI thát Virtualbox uses doesn't function. In add-on, make sure that 'Enable IO APIC' is usually checked. Then, click on on the 'Velocity' tab and check out both of the options right now there. I'm not certain whether these choices actually matter (EFI will be definitely the most important variable), but it's better safe than i am sorry. Once you're completed with that, proceed to the settings for 'Storage space'. In the storage space tree container, you'll find a Compact disc icon labeled 'Clear'.
Click on on it and click 'Choose a digital CD/DVD disk document'. In the windowpane that jumps up, select the.iso copy of iBoot. On the installation page for Mac pc OSX, the tough cd disk/disk partition should today be displaying up. Select it and continue to the Install Overview page.
Click on the 'Customize' switch on the bottom part left of the Install Overview screen, and uncheck additional options to speed up the process. Install Operating-system A. The process takes me 20-30 moments. Once carried out, the pc will restart. Right-click on the little CD image in the bottom ideal of the Virtualbox window again, and change back to iBoot.
The iBoot menu (with the tonymacx86 apple company at the top) will show up once again. Select your brand-new Snow Leopard installation from the iBoot menu, and press Enter to shoe it up. However, Snowfall Leopard earned't allow you conserve your modifications usually, since 'org.Chameleon.boot.plist' is definitely a system-protected file. Rather, you'll have got to conserve a fresh edition of this document to someplace arbitrary (like the Desktop of Macintosh OS Back button, for instance). After that, remove the older version of org.Chameleon.boot.plist, and change it with the fresh edition that you have edited.
Once that's carried out, switch off the digital machine. Following, open up the Order Quick in Windows (create sure you are logged into an Officer account on Home windows). You can do this by opening the Start Menus, and keying in 'control quick' into the Begin Menu research bar. After that, kind the adhering to control into the Command Prompt. Cd 'D: Program Data files Oracle Virtualbox' This command word will change the focus of the Command Prompt to the program folder for VirtuaIbox (if you set up Virtualbox someplace different, after that alter the control to wherever you installed it). Next, type in this order: vboxmanage setextradata 'Name of digital device' 'CustomVideoMode1' '1920x1080x32' This control activates 'vboxmanage', á command-line plan included with Virtualbox that allows you to modify the qualities of your virtual machine, including its built-in resolutions. Replace 'Name of digital device' with the name of your digital machine- you can find the title of your digital device in the left pane of the Virtualbox major window (in the scréenshot below, my virtual machine is usually named 'Mountain Macintosh 2').
Replace '1920x1080x32' with whatever quality you're also using. Once that's completed, begin your virtual machine once again. It will right now shoe in complete resolution. Step 7: Change off up-dates. First, an essential take note: Perform NOT Revise NORMALLY. This can be a fantastic rule of Hackintoshing, and it applies to virtual machines working Mac Operating-system X as well.
Anyways, Mac pc OS A is established to immediately upgrade itself. To switch off automatic updates, click on the Apple image in the top remaining hand corner of Mac OS Back button, proceed to System Choices, and after that click on on 'Software Upgrade'. Uncheck the container that says 'Check for Up-dates'. Action 8: Updating your digital machine Therefore, maybe you don't would like your virtual machine to be trapped on Mac OSX version 10.6.3 permanently.
Well fortunate for you, it's possible for you to update Mac OS Times without it overflowing. Very first, download the combination revise for the edition of Macintosh OSX that you want.
Unlike regular improvements from the Software program Update application (that you should have converted off in Phase 9), a combo update is usually installed personally. If you wish to update your digital device to Mac pc OSX version 10.6.6, simply research '10.6.6 combination update' on Search engines.
The established combo revise from Apple company is literally the very first search outcome. Download the up-date. This will consider a even though, since most of the combination updates are usually massive.
As soon as you're accomplished, click on 'Machine' on the best of your Virtualbox screen, and 'Consider Snapshot'. Generally, this saves your device's current state, therefore if you accidentally make Macintosh OS Times hit up while updating, you can just recover it to your previous condition. After you've used a overview of your device's current state, run the revise. This will get another 20-30 minutes. As soon as the update coatings and demands you to reboot your virtual machine, DON'T RESTART. Rather, open up the web internet browser in your Macintosh OS Back button virtual device, and download the heritage kernel for the version of Mac pc OSX that you're upgrading to. If you're also updating your digital device to Mac OSX version 10.6.6, search '10.6.6 legacy kernel' in Google.
Look for a heritage kernel by 'nawcóm'. All of thé legacy kernels are usually obtainable on, but like many websites, the company is terrible. It's easier just to Google his things. Once you've discovered the appropriate legacy kernel, set up it. Then you can restart your personal computer to total the system revise. If everything went best, your digital device should nevertheless be capable to boot.
Mac Os X Snow Leopard
Hooray!:M Plus, Macintosh OS X will possess been updated. Recap Setting up Mac OS Back button on a virtual machine is certainly excellent practice for the real thing: installing Mac Operating-system A on your real computer. Don't obtain too comfy, though.
Os X Snow Leopard Download
Likened to most computer systems, Virtualbox digital machines are usually extremely 'vanilla', signifying that they're also very compatible with Macintosh OS X from the begin. After all, sound and ethernet function from the start. You can't count on getting that fortunate with a genuine Computer.
And actually if you wear't program on carrying out this for actual, with a Hackintósh, it's still a really cool thing to consider out over the weekend break.
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.
Mac Os Snow Leopard Retail Dvd Download Torrent
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.

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.
