How to install OS X Mavericks in Virtualbox with Niresh, which is great practice for installing Mac OS X on your actual computer. And now that Apple has released OS X Mavericks, it's only fitting that we show you how to install Mavericks in a virtual machine as well.

Unlike in previous versions of this guide, we'll be using the newly- popular instead the old i. Atkos distro (which is no longer publicly available for free). While we've already shown you how to , it also works great with virtual machines. Computer Requirements. You need a computer with Windows to run Mac OS X on Windows (of course). If you have a 3. 2- bit copy of Windows, you can only install Mac OS X Snow Leopard on Virtualbox.

You will need at least 4 GB of RAM and a dual- core (two core) processor or better. Personally, the computer I was using for this had a 4- core processor and 1.

GB RAM, which is way more than enough. You also need about 1. GB of unused hard drive space.

If it doesn't directly tell you how many cores your processor has, look up your processor model on Wikipedia or Google. You also want to find out whether your processor is made by . While Niresh technically works with both types of processors, if you have an AMD processor, you'll have to perform a few extra steps during the installation (and the final result may not work as well, either).

OS X EI Captain is now available for easily download and at present, this new revolution is known to all. This lucrative downloading opportunity is now widely grabbed. Download the latest pre installed VirtualBox images as VDI disk file completely free here. Linux, Microsoft OS and other open source VirtualBox image download sites. Last time when I wrote the How to Install Snow Leopard on VMWare guide, I had users who were seeking Virtualbox version, and I had it promised. VirtualBox is a general-purpose full virtualizer for x86 hardware, targeted at server, desktop and embedded use.For a thorough introduction to virtualization and.

General Requirements. Virtualbox : This virtualization suite is free, and though it doesn't offer official support for Mac OS X, it works well enough. Niresh Mavericks: Unfortunately, the standard .

Instead, you'll have to pirated . On the Niresh website, you'll be given an option to either download the .

Download the ISO version- - the USB version (which is an Apple DMG file) doesn't appear to work in Virtualbox. Step 1: Prep. Download Virtualbox, install it, and open it up. Also, if you want to be able to view USB devices from your Mac OS X virtual machine, download the Virtualbox Extension Pack and run it before going to Step 2. Step 2: Create a new virtual machine. Give your new virtual machine a name, and choose .

Choosing 3. 2- bit will result in a critical . Every time you turn on Mac OS X, that RAM that you assign here will be used to run the virtual machine.

The RAM will be given back to your normal computer after you turn Virtualbox off. Virtualbox will ask you what type of disk you want to create: VDI, VDMK, or VHD. VDI is the original format for Virtualbox, while VDMK is the format used by VMWare. If you're considering getting a copy of VMWare, you might want to choose VDMK. Otherwise, just choose VDI.

I recommend creating a dynamically expanding disk; the only other option, fixed- size storage, will eat up your hard drive. Step 3: Give your new virtual machine an operating system.

But don't stop now- -you still need to change a few settings before your machine will actually work. Your new virtual machine will show up on the left column of the Virtualbox start page. Once the settings open up, go to . This is by far the most important single setting that you will need to change.

Unfortunately, Mac OSX requires . In the storage tree box, you'll see a CD icon labeled . Click on it and click . In the window that pops up, choose the . Niresh; this file will probably be named . You will come up to the Niresh boot screen, with one option to select: OSX- Mavericks.

Type the boot flag . If this is this case, you will have to trick Virtualbox into thinking that your processor is actually an older model. To do this, open the Command Prompt in Windows (make sure you are logged into an Administrator account on Windows).

You can do this by opening the Start Menu, and typing . Then, type the following command into the Command Prompt. Next, type in this command: VBox.

Manage modifyvm < Name of virtual machine> - -cpuidset 0. This command activates . This command should do the trick.

Oh no, the page is blank! We'll have to fix that. To do this, start up Disk Utility (located under the Utilities menu). Click on the Virtualbox hard disk in Disk Utility and erase it. Don't worry, there's nothing important on it. This is where using a distro becomes really useful: Niresh allows you to install extra Hackintosh drivers and kexts, straight from the OS X Mavericks installer.

The are only two things you need to change: Uncheck Install Network Drivers (Kexts). This option is checked by default.

Normally, it will allow Niresh to automatically detect your computer's ethernet controller and install the appropriate ethernet kext, so that your internet will work immediately in Mac OS X. However, this feature doesn't really work in Virtualbox. All it does is break the internet in your virtual machine. Uncheck Graphics - > Graphics. Enabler=Yes. This option is also checked by default. Normally, it allows Mac OS X to work better with your computer's graphics card. However, Virtualbox doesn't support Mac OS X graphics anyways, so this option is essentially pointless for virtual machines.

All it does is decrease the default screen size of your virtual machine from 1. When the installation finishes, Mac OS X will crash into a black screen with white text. This is normal; Mac OS X has installed successfully.

Now proceed to the next step. Step 5: Boot it up. Restart your virtual machine, and eject Niresh from your virtual DVD drive. To eject Niresh, right- click on the CD icon at the bottom right of the Virtualbox window, and un- check the Niresh file (probably named .

Your mouse cursor will probably be trapped inside the virtual machine. Press the right . Now, at the bootup screen, you'll see an icon for the hard drive where you installed Mavericks (also, the screen of your virtual machine might be bigger than before). After a few seconds, Mavericks will boot, and you should eventually be led to the Mac OS X setup screen. Fill it out, then mission accomplished! This concludes the first part of the guide.

You'll have to wait a few minutes for Niresh to finish installing its extra kexts and drivers, but after that, audio and ethernet should both work automatically. However, you're not done yet!

You still have to enable increase the screen resolution of your virtual machine, which is probably still stuck at 1. NOTE: One common issue with Niresh is that it tends to lag out of the account creation process, and skip straight to the Mac OS X login screen before you can make your own account. If this happens, simply log into Mac OS X with the following credentials: Username: root. Password: niresh. This will log you into the . From here, open the System Preferences app, go to . Anyways, when you first use your virtual machine, you'll probably notice one thing: your screen resolution is 1.

Graphics. Enabler=Yes). Since Virtualbox doesn't . But here's how you can change it anyways. First, you need to access org. Chameleon. boot. plist, the settings file for your virtual machine's Mac OS X bootloader. You can do this from Finder, the file browser built into Mac OS X.

However, Finder hides your hard drives in Mavericks by default. To unhide them, open Finder, and click on File - > Preferences in the menu bar at the top of Mac OS X. Open the file org. Chameleon. boot. plist. Between < dict> and < /dict> in the file, insert the following line.< key> Graphics Mode< /key>.

Next, turn off your virtual machine. Open the Command Prompt in Windows (make sure you are logged into an Administrator account on Windows). You can do this by opening the Start Menu, and typing . Then, type the following command into the Command Prompt. Next, type in this command: vboxmanage setextradata . Once that's done, start your virtual machine again. Your virtual machine will now boot Mavericks  in full resolution.

Congrats! Recap. I'll just repeat what I said in my other two Virtualbox guides. Installing Mac OS X on a virtual machine is excellent practice for the real thing: installing Mac OS X on your actual computer. Don't get too comfortable, though. Compared to most computers, Virtualbox virtual machines are very .
