Go for a system cleanup and fast backup

The first step towards a clean install, is a drive format. But act with caution! Before you do anything drastic, make sure you cleanup and backup your Mac to keep your important files.

Start with a system clean-up. Okay, that’s actually an euphemism for: delete everything you don’t need, throw away any duplicates and erase all the useless data.

Don’t know how to do that exactly? Check out How to clean up your Mac for a detailed and easy way to perform a thorough cleaning.

There are going to be some important files you will want to keep. Be it files, documents, photos, movies or other apps, you’ll want to create a backup for them. Where? That’s up to you. You can choose either iCloud or any external storage device with enough space.

Now it’s time to wipe your Mac clean. But you did perform a Mac backup, right? Good! Then you can format the drive! Here’s how:

Go to Applications > Utilities and click on Disk Utility. From here, select the drive and hit Erase, as you select Mac OS Extended (Journaled) as the format type.

Before you start new life with the new macOS, get equipped with a couple of backup and maintenance tools. They will save you should something goes wrong. The good solutions are Get Backup Pro or Disk Drill.
And the last thing before we start. A new OS needs a fresh Mac, so trim down the fat on your system. Use an app like CleanMyMac X to remove all system junk, large hidden files, and old apps' leftovers.

During a recent pentest, I needed to throw together a macOS virtual machine. Although there was lots of guides around the web, none seemed to work from start to finish. This post contains the steps I extracted from various resources in order to get a fully working High Sierra install within VirtualBox 5.

Step 1: Download The High Sierra Installer

To do this, you need to be on an existing macOS system. I was unable to find the download within the App Store itself, but following this link opened the App Store at the correct page: https://itunes.apple.com/us/app/macos-high-sierra/id1246284741?mt=12

After opening the aforementioned page in the App Store, start the download, but cancel the installation when it starts.

You can then verify that the installer has been downloaded by checking that '/Applications/Install macOS High Sierra.app' exists.

Step 2: Create a Bootable ISO

Next, you need to create an ISO from the installer application that was downloaded in step 1.

Running the below commands will create an ISO on your desktop named HighSierra.iso:

Step 3: Creating the Virtual Machine

I experimented with a few different settings in regards to the CPU and RAM allocation. I didn’t find a combination that didn’t work, but create a VM with the following things in mind:

  • Ensure the name of the VM is MacOS (ensure to keep the same casing)
  • Ensure the type is Mac OS X and the version is macOS 10.12 Sierra (64-bit) (there is a High Sierra option too, but I chose Sierra by accident and it worked)
  • Untick Floppy in System > Motherboard > Boot Order
  • Use >= 4096 MB of memory in System > Motherboard
  • Use >= 2 CPUs in System > Processor
  • Use 128 MB of video memory in Display > Screen
  • Optionally enable 3D acceleration in Display > Screen
  • Remove the IDE device in Storage > Storage Devices and replace it with a SATA controller
  • Add a new hard disk device under the SATA controller with >= 60 GB of space
  • Ensure an optical drive is present under the SATA controller and mount the previously created ISO to it
  • Untick the Enable Audio option under Audio

After creating the virtual machine with the above configuration, hit OK and exit the settings screen. Now, a number of extra options need to be set.

If you’re on Windows, you’ll need to cd into the appropriate directory under the VirtualBox installation path to run VBoxManage. For Linux users, this should be in your PATH variable already:

After running the above commands, the VM should be ready to boot!

Step 4: Installation

This is where near enough everything I read stopped, despite there being one more problem in the way - UEFI.

Boot into the VM, go into Disk Utility and erase the virtual disk that you added to the machine.

After erasing the disk, start the installation procedure. After a short amount of time, it will reboot the VM.

Once it reboots, it’s going to boot back off the ISO again, once it’s done this, just shutdown the VM and eject the disk [the ISO] and then start the VM again to boot from disk.

On the next boot, it should boot into the installer that was copied to disk, but instead, you will be presented with a UEFI shell like below:

To continue the macOS installation, follow these steps:

  1. Type exit and hit return
  2. Select Boot Maintenance Manager and hit return
  3. Select Boot From File and hit return
  4. You will see two partitions, select the second partition and hit return
  5. Select macOS Install Data and hit return
  6. Select Locked Files and hit return
  7. Select Boot Files and hit return
  8. Select boot.efi and hit return

After following these steps, you will boot into the remainder of the macOS installation. From here, just follow the steps as per a regular macOS installation.

The next time you boot your virtual machine, you will not have to go through the UEFI shell; it should work without any further problems.

Step 5: Tweaking The Resolution

As there is no VirtualBox additions for macOS, the screen resolution won’t automatically change. If you know what resolution you wish to use, however, you can set it manually.

Ensure the virtual machine is powered off, and then run the following command; replacing 1920x1080 with whatever resolution you would like to use:

After running the above command, the next time you boot the machine, it will use the resolution specified.
