Major release of Mac OS X. Mac OS ISO Download for Virtualbox Feb 05, 2018 Mac OS X El Capitan ISO. OS X Mavericks (version 10.9) is the tenth major release of Mac OS X. The most relevant program for Os x mavericks iso is Mac OS X Mavericks 10.9. Get a free download for Operating systems software in the specialized download. 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 'OSX-Mavericks.iso'). Your mouse cursor will probably be trapped inside the virtual machine. Press the right 'Ctrl' key on your keyboard to allow your mouse to escape. Open VirtualBox and create a new virtual machine. Use the following steps to create a new virtual machine in VirtualBox: Open VirtualBox. Click New below the gear icon at the top. Click the arrow pointing down next to 'Machine Folder' and select a folder to install the virtual machine. Use the drop-down menu next to 'Type' to select 'MacOS X.' The steps I have taken: Attach HackBoot1.iso, disable EFI for the VirtualBox guest and boot up; Hackboot starts up. Attach the OS X Mavericks bootable ISO image. Therefore, in here one of the most important work do that is copying the VirtualBox. Because without this code you are unable to run Mac OS X Yosemite on VirtualBox.

Installing Mavericks inside a virtual machine is fairly easy, but there are a few tricks to be aware of if you’re on a newer Mac. Credit to Natsuki’s post for sharing how to get the Mavericks installer to run on Apple computers with Intel Haswell CPU’s. Natsuki also notes a workaround for Apple computers with ECC RAM that requires the removal of a kernel module from the install image using iesd.

Download and install the latest VirtualBox for OS X hosts from here. We’ll be using VirtualBox so that anybody can follow these steps.

Download the Mavericks Installer App through the App Store.The Mavericks installer is provided for free by Apple for users to upgrade their computers to the latest version of OS X. We’ll be making use of the install image provided by this application to install Mavericks within a virtual machine.

While we’re waiting for the Mavericks Installer to download, lets get started on configuring our new Virtual Machine.

Create a New Virtual Machine

Lets call it “Mavericks”

Lets allocate 2 GB of my host machine’s 8 GB of RAM

Lets create a new blank disk image for this machine

The VDI format should be fine for what we’re doing

A dynamically sized disk should also be fine for what we’re doing

Lets call this disk image “Mavericks” too

And we’re successfully created our virtual machine

We need to check if your computer has an Intel Haswell processor. We’re going to use “About This Mac” to check.

Lets launch “About This Mac”

Click on “More Info…”

If you see “Late 2013” or later, we’ll need to change the CPUID for our virtual machine so the installer image boots

We need to determine the name of the virtual machine, if you called it something other than “Mavericks” you’ll need to use the name you get from this command:
VBoxManage list vms

Now that we have the name, we can specify the CPUID for that virtual machine

Run VBoxManage modifyvm Mavericks --cpuidset 00000001 000306a9 00020800 80000201 178bfbff (Substitue Mavericks with what you got from VBoxManage list vms if you have something different)

In your terminal, run sudo gem install iesd

iesd is a Ruby applicaiton with extracts the installer disk image from the installer application to for use as a boot disk for your virtualization software.

Run iesd -i /Applications/Install OS X Mavericks.app -o Mavericks.dmg -t BaseSystem

Now you’ll have a Mavericks.dmg inside your user’s home folder.

Now we’ll attach this disk image to our virtual machine

Click on the “Storage” text of this new machine

Click on the “Empty” list item

Click on the CD icon to “Choose A Virtual CD/DVD Disk File…”

Choose the Mavericks.dmg file that iesd produced in your home folder

Now we’re set to install Mavericks within the VM!

Wait for the VM to boot. You’ll see plenty of black on white text scroll by with some errors and warnings, but they are acceptable.

And we’ve booted!

The mouse will be very laggy on this screen because of the animation, so it may be easier to hit the “Enter” key than to navigate to the next button with the mouse.

Before continuing with the installer, we need to format the blank disk so that the installer detects it as an install location.

Go to “Utilities” -> “Disk Utility…” to launch the Disk Utility

Select the “VBOX” disk and go to the “Erase” tab. Give the disk a better name than “Untitled”, I’m partial to “Mavericks” and then click “Erase”

Click “Erase” again when prompted

Wait for the disk to be erased. Once it’s ready, the named disk will appear in the top left of Disk Utility.

Quit Disk Utility

Now we’re all set to install Mavericks!

Click “Continue” on the Installer

Agree to the EULA and note the section that permits what we are doing

Select the volume we created with Disk Utility and click Install

It will take a little over 20 minutes for the installer to run

Restarting

We’ve successfully installed Mavericks. Lets take a snapshot of the machine at this point in case we ever want to reset back to the big bang.

After the Machine restarts, we’re actually going to want to “Power off the machine” so that we can take a snapshot of the virtual disk and detach the install disk

On VirtualBox Manager, click on “Snapshots” for this machine

Click the Camera icon to take a snapshot

Name your snapshot

Snapshot created

Lets not forget to detach the the installer image.

Switch back to the “Details” pane and click on the “Storage” text

Click on the installer image, then the CD icon, and finally “Remove disk from virtual drive”

From here, you’re good to go to start the virtual machine again and continue with the installer. I’d recommend taking another snapshot after you’ve set up the virtual machine so that you have another checkpoint to restore to.

A couple caveats here and also here (under “Mac OS X guests”). There aren’t any Virtualbox Guest Additions for OS X and the default resolution of the machine is 1024×768.

From the VirtualBox documentation, it is possible to set higher resolutions with VBoxManage setextradata 'VM name' VBoxInternal2/EfiGopMode N where N values of 0-5 correspond with 0=640×480, 1=800×600, 2=1024×768, 3=1280×1024, 4=1440×900, 5=1920×1200

Thanks for sticking through this how-to. I hope that this VM image will be useful in testing your OS X applications. Don’t forget to make liberal use of snapshots; and remember that you can create lightweight, snapshot-based clones of this VM if you need more than one.
