Start the macOS Virtual Machine in VirtualBox.

Next, in “Storage,” add an optical drive in “Controller: SATA,” and then you’ll click on “Choose disk” and navigate to the location where you have your Mac ISO file located.

The storage made for your Mac VM should be located where enough space is available either on your Chromebook, USB flash drive, or SD card.

In “Display,” you can use the maximum amount of video memory that’s available.

Where it says “Hardware Virtualization,” ensures that both the “Enable VT-x/AMD-V” and “Enable Nested Paging” are both checked “off.”

Then, click on the “Acceleration” tab.

Go to “System” and where it says “Extended Features,” uncheck “Enable EFI (special OSes only)” and uncheck “Hardware Clock in UTC Time.” Make sure the base memory falls within the green line.

When your Mac Virtual Machine gets created, you’ll want to go into “Settings” in the Oracle VM VirtualBox Manager. Click the “Create” button once you’ve finished.

The final step in creating your Mac VM is selecting the file location for it and choosing the size you’d like it to be.

Select a dynamically allocated hard disk file on the next screen and click the “Next” button.

On the next screen, select “Create VDI (VirtualBox Disk Image)” and click the “Next” button.

The size recommendation is 20GB for the VM you can use a USB flash drive if your Chromebook has less space than that available.

Next, you’ll create a virtual disk image.

Now allocate the memory size for your VM, but stay within the green line otherwise, your VM is going to have some operational issues such as crashing, which you don’t want happening.

Give your virtual machine a name like Mac.

In the Oracle VM VirtualBox Manager, select “New.”.

Now, type “sudo sh setup-headers.sh” which executes that header script.

Type “wget ” and then press “Enter” on your Chromebook keyboard.

Be sure you’re located in the home directory. Once you’re in the terminal in Ubuntu, you’ll download another script that sets up your headers. You’ll now be in Ubuntu Linux and need to open the terminal.

Now, you’re going to start up Ubuntu Linux by typing “sudo startunity.”.

Then, you’ll get the script to execute itself by typing “sudo sh ~/Downloads/change-kernel-flags” and pressing “Enter” on your Chromebook keyboard.

Then, type “wget ” and press “Enter” on your Chromebook keyboard.

Next, type “shell.” Then, download the script that someone already wrote to make this process easier.Press “ctrl + alt + t” on your Chromebook’s keyboard, which in turn opens Crosh in a new tab of your Chrome Browser.To install the Ubuntu distribution of Linux, you will first need to get into the Chrome OS developer shell, Crosh.
