Overview of Mac OS X El Capitan on Virtualbox on Windows

The power technologies in OS X El Capitan were built with the capabilities of recent processors and therefore the demands of recent apps in mind. The new power technologies work together to realize substantial power savings while maintaining—and in some cases even improving—the responsiveness and performance of your Mac.

These technologies are rooted during a few key principles:

• Just work for existing apps. No changes to applications should be needed, though small changes may facilitate additional power savings.
• Keep as many processor cores idle as possible given the demand for CPU.
• When on battery power, only work that the user is requesting or that’s absolutely essential.

USB Power Management

Traditionally, USB device power management is completed manually, with a function driver making explicit suspend or resume calls on a USB device service. This is often error-prone and leads to overly complex driver code to manage the power state.

USB in OS X El Capitan has been completely implemented to profit from an equivalent USB architecture and aggressive power management policy adopted by iOS. Each endpoint in a device is often given an idle timeout in milliseconds, and an endpoint is taken into account idle if a lively transfer hasn’t completed within that timeout. The device has an idle state also, which may be a logical AND of the idle state for the endpoints related to the device. Only the device idle timeout expires does the OS pause I/O on the bus and electrically suspend the device at the port.

The idling system is a crucial advance because drivers don’t have to actively participate in power state transitions.

System Integrity Protection

System Integrity Protection may be a policy introduced in OS X El Capitan to assist prevent malicious software from performing harmful actions on your Mac. System Integrity Protection prevents software from modifying files and folders owned by the system, albeit the software is run because of the administrator or with root privileges.

Examples of paths within the filing system that are protected include the following:

• System folder
• /bin/
• /sbin/
• /usr/ (with the exception of /usr/local/)

In addition, System Integrity Protection prevents modification of applications and utilities that are installed with OS X and prevents changes to your boot volume without your data.

Data Compression

Four different compression algorithms are supported, giving developers a choice between speed, compression rations, and interoperability with non-Apple devices.

LZ4

LZ4 is a particularly high-performance compressor. OS X implements encoder support at level 6 only. It uses a dictionary compression scheme and features a high compression ratio and a variable compression dictionary size.

ZLIB

Zlib may be a lossless data compression library to be used on a spread of operating systems. OS X implements a ZLIB encoder at level 5, which provides an honest balance between compression speed and compression ratio.

Following are the installation along with the interfaces steps:

Mount Installer DMG record to macOS

• hdiutil interface/Applications/Install OS X El Capitan.app/Contents/SharedSupport/InstallESD.dmg – no verify – no browse – mount point/Volumes/Install

Make a DMG Disk

• hdiutil make – o/tmp/elcapitan – size 7900m – volname elcapitan – design SPUD – fs HFS+J # hdiutil affix/tmp/elcapitan.dmg – noverify – mountpoint/Volumes/elcapitan

Download Mac OS X El Capitan on Virtualbox on Windows

You can download the Mac OS X El Capitan on Virtualbox on Windows by accessing the link below. Also, make sure that you have enough back up before you proceed with the same. There are a lot of duplicate ISO images on the market and it is best to download the same from a trusted source.

Windows, macOS – which one do you want to use today? On a traditional setup, you’re stuck with one or the other. But with virtual box, you actually have macOS on a Windows PC.

It’s the freedom that computer users have enjoyed with Linux and other operating systems.

But Apple has made it difficult to install their operating system on anything other than their own hardware. All of that is changing, and Virtual Box is responsible for it and the rise of the Hackintosh.

New to hackintosh? Learn more about it in our what is hackintosh? overview.

Note: A lot of people will be able to get a mac virtual machine one Windows running smoothly, but sound doesn’t seem to work well. That’s really not an issue because you’ll still be able to access all of your apps and software.

I also recommend that you have access to a real Mac. You might be able to find some distributions of the High Sierra ISO online, but there is always a risk when downloading from an unofficial source. Instead, borrow a Mac from a friend, or use your own and download the High Sierra OS from the App Store.

Everything You Need to Get Started with Installing macOS on VirtualBox

Before we go through the steps on how to install macOS on Virtual Box, let’s get everything together that you’ll need to get started.

1. Open up your Mac
2. Go to the App Store
3. Type in “High Sierra”

You’ll want to search for your desired operating system (we’ll be using High Sierra), and Download it.

Note: You’ll need a decent computer to be able to run Virtual Box. Your computer will need to meet these minimum requirements:

• Dual core processor
• 4GB Ram or higher
• 64-bit

If your computer doesn’t meet these requirements, you won’t be able to run macOS properly. You’ll be able to download VirtualBox from the official website. I’m not going to go through the installation process, as the website will have all of the information you need to be able to install VirtualBox.

I do recommend that you read all of the documentation and ask any questions that you have in the community section of the website.

VirtualBox 6.0 was just released, so it’s definitely a great time to get started with your own macOS.

Extract macOS Sierra

Make sure you’ve downloaded High Sierra, and then you’ll want to run a few commands from your terminal . You’ll be able to open the terminal at: Applications > Utilities > Terminal. Once inside of the terminal, you’ll want to run the following commands:

Go to your desktop and rename the file, removing the “.cdr” extension. You need this extension to read “.iso” for it to work properly.

You’ve successfully created your own ISO file so that you can bootup your macOS.

The next step is to copy the file over to your Windows machine (using a large USB drive seems to work best). This file will be mounted in your virtual machine later on in the article, so it’s very important that this step is completed successfully.

Creating a mac Virtual Machine on Windows

You’ll want to create a virtual machine, and this is really easy. You’ll open up VirtualBox and click New. You’ll want to have the following parameters selected or entered before clicking Next.

• Name: High Sierra
• Type: Mac OS X
• Version: Mac OS X (64-bit)

Pay attention when selecting the version because you may find that High Sierra is offered as a version when you go to install it. But if it’s not, you can just choose the settings I listed above and they should work fine.

Mac Os X El Capitan Iso For Virtualbox 7

You’ll then be proceeding through all of the settings.

When you come up to the RAM setting, you’ll want to be generous. VirtualBox requires a minimum of 4GB or RAM to run, but the more the better.

Why?

You’ll want to provide at least 4GB to your macOS, or 4096MB to be precise. A general rule of thumb is that if you can spare it, supply more RAM to your virtual machine. RAM will allow the operating system to put more information into memory and retrieve it faster.

For better overall performance, supply as much RAM as you can.

The next steps are also important, and they’ll include:

• Hard Disk: Choose the “Create a virtual hard disk now” setting.
  • Choose VDI when choosing the hard disk type.
  • Choose Fixed Size instead of Dynamic for added speed.
  • Set the size of the drive to at least 25GB.

You’ll now have your virtual machine using the RAM and disk space properly, and you’ll have to work your way through a few screen prompts before having everything setup properly.

Configuring Your VirtualBox to Run macOS High Sierra

We’ve made a lot of progress so far, and now it’s time to configure your virtual machine properly. You’ll see in the main window of VirtualBox that “High Sierra” is listed. Click on this and then click on the “Settings” button.

You’ll want to go to “System” and make sure that the following are unchecked on the Motherboard tab:

• Floppy
• Network

Click on the Processor tab and make sure that you have 2 or more CPUs set for your virtual machine.

Download Os X El Capitan Iso

The next few settings are rather simple:

• Display: Video Memory with a minimum of 128MB
• Storage: Click “Empty” and then click on the CD at the top right. Choose your High Sierra ISO file

Now you’ll need to click “Ok,” and save all of the changes you’ve made. Close out your VirtualBox now.

Apple is very strict on the system that their operating system runs on, so it’s very important that you do your best to configure your virtual machine in such a way that it tricks the installer to thinking you’re on a retail machine.

We’ll now be going into the Windowscommand prompt.

You’ll do this by:

• Clicking the Start Menu
• Typing “Command Prompt”
• Right-clicking on the Command Prompt desktop app
• Choosing Run as administrator

It’s very important to follow all of the following command prompts exactly. Your goal is to run each command, one by one, hitting the Enter button and waiting for the command to complete successfully.

Remember that VirtualBox needs to be closed before running these commands, or it won’t work properly.

You have to make sure that the virtual machine is properly named “High Sierra” for this method to work. If not, you’ll be able to go back and make changes to the name to get everything to work properly.

Once all of the commands are completed, and there are no errors, you’ll then be able to open up your VirtualBox and get macOS High Sierra installed properly on VirtualBox.

It’s a long process, but we’re almost done with your installation.

Running VirtualBox and the macOS Installer

Download Os X El Capitan Iso Latest

You’ve almost learned how to install macOS on VirtualBox entirely, and we’re on the home stretch. You’ll want to open up your VirtualBox and then click on your virtual machine that you set up earlier.

Now, click “Start.”

There will be a lot of information displayed on the screen as everything starts running. I recommend stepping away from the machine and letting it run for a few minutes before coming back. Some errors can hang for 5 minutes or longer.

If you’ve done everything properly, you can be confident that the installer will boot properly.

You’ll eventually be presented with the option to pick a Language. If you’ve reached this point, you’re doing very well and are almost ready to run your macOS.

The next steps can be followed:

• Choose your desired language, and click
• Click “Disk Utility” and then
• Click “View” and then “Show All Devices.”
• Click on your empty virtual drive that has been setup and click “Erase.”
• Choose the following settings:
  • Name: Macintosh HD
  • Format: Mac OS Extended (Journaled)
  • Scheme: GUID Partition Map
• Click “Erase” and close Disk Utility when the process is complete.
• Click “Reinstall macOS.”
• Click “Continue.”

Mac Os Iso File For Virtualbox

You’ll come up to one point where you’ll be asked to choose a hard drive, and you’ll want to select the Macintosh HD partition that you just created with the Disk Utility.

We’ve successfully copied all of the files on the virtual machine, but we’re not done just yet.

Exit your virtual machine and then go back to your virtual machine’s settings. You’ll need to change up your Storage settings. Click on your ISO for High Sierra in the “Storage Tree.” You’ll click that CD icon just like we did earlier and then choose “Remove Disk from Virtual Disk.”

You need to do this to unlink the ISO from your virtual machine.

Start up your virtual machine and you should come across a black screen with the EFI Internal Shell. You’ll want to look for FS1. If this is listed in yellow, click on the virtual machine and then type fs1: and hit the Enter button.

You should be in the fs1 directory.

Mac Os X El Capitan Iso

Type in the following commands:

1. cd “macOS Install Data”
2. cd “Locked Files”
3. cd “Boot Files”

Now we’ll run the installer by running: boot.efi and hitting enter.

If everything goes well, you’ll come across a graphical installer and will just have to work through the prompts. The virtual machine will reboot eventually and then you’ll need to go through the settings and the rest of the setup process.

Soon enough, you’ll be right inside of macOS, where you’ll be able to start using your mac virtual machine on Windows.

Mac Os X On Virtualbox

Having a virtualbox mac OS is the easiest method of using mac as and when you need it. In addition, using virtualbox is far less complicated than the dual boot hackintosh method we have looked at previously.

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.

Os X El Capitan 10.12

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.

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.

Download Os X El Capitan Iso Full

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:

Mac Os X El Capitan Iso Download Free

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.

Free El Capitan Download

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