Well Holy Hannah, I received my first Twitter DM over a blog post I've written. I'm officially a pro now 🧐

OS X keeps giving me errors with different apps when I try to create a boot usb Install Disk Creator gives me - Invalid macOS installer; The. Install macOS High Sierra in VirtualBox on Windows 10: 5 Steps 1. Extract the Image File with Winrar or 7zip. Step 1: Go ahead and install WinRAR. (I have included the latest (March 2018) link for WinRAR for you). Step 2: Once you’ve done that then right click on macOS High Sierra 10.13 file that you had downloaded.

The DM was from a user that was having some issues with the instructions I provided on a post I wrote in 2015 for S&W here about how to run the then-current release of macOS inside a Vagrant box.

So I thought, what the heck that blog post is 2 yrs old and in computer time that's pratically middle aged. And Trump's been president for essentially a full year now and let's not even talk about what that's done to the flow of time.

Downloads

macOS High Sierra from the App Store
- Image is approximately 5.2 GB
latest Vagrant from Hashicorp
- As of this post the latest release is 2.0.1
- Image is approximately 70 MB
latest release of VirtualBox from Oracle
- As of this post the latest release is 5.2.2
- Image is approximately 93 MB
Homebrew - a package installer for macOS. Not required but recommended / encouraged.
iTerm - an alternative to the Terminal app included in macOS. Again, not required but recommended. For the rest of this post 'terminal' can be used interchangeably for iTerm or Terminal, whichever you chose.

Protip: you can install Vagrant and VirtualBox using Homebrew:

Open terminal
Install Homebrew (brew) using the command provided on the link above
Install Vagrant
brew cask install vagrant
Install VirtualBox
brew cask install virtualbox

The main benefit of using a package installer like this is that your packages, like Vagrant and VirtualBox, can now be kept updated with brew update rather than manually downloading / updating package installers from various websites.

For the VirtualBox install you will be prompted to open System Preferences → Security & Privacy at some point. If you don't do this 'fast enough' (by the system's pre-programmed determination) then the install may error out. Fear not! It caches the install like so:

So if the install halts for this reason, or because Connection reset by peer (typically that means slow internet connection), or for any other reason, then you can just hit the up arrow to re-run the last command and hit Enter. Just make sure you fix whatever it asks you to first 😉

What this will essentially look like in terminal:

The Gritty Bits

Ok, so now that we have All the Things we need to do .. quite a few steps, actually.

Creating your ISO File

First, when you download High Sierra, or any other macOS release to date, you are downloading the file as a DMG, which is a proprietary Apple disk image format. In order to run macOS in VirtualBox, we'll need to convert the DMG file to a more general format such as an ISO. To do this, we're going to start by converting the installer DMG that we downloaded from the App Store into an image of the full OS, store that in a DMG, and then use a utility called PowerISO to do the final conversion.

If that just read like a paragraph of panic, don't worry! We're going through it step by step.

The output will look like this:

Troubleshooting

What to do if you see the following error:

This most likely means that you've already mounted the InstallESD image. Go into Disk Utility and unmount it:

This likely happened when the High Sierra download completed and immediately opened the installer.

Using your VHD file with VirualBox

Open VirtualBox:

Click New:

Choose a name, Type is 'Mac OS X', and Version is 'macOS 10.13 High Sierra (64-bit)'. Then click 'Continue':

The default memory is 2 GB, I recommend upping it to 4 GB though if you can:

Choose 'Create a Virtual Hard Disk File now' and 'Create':

For the curious
The image manipulations above, with arrow / blurring of text / etc., were done with the Skitch app. You only need an account to save in Evernote - account-less you can just locally save / export to whatever image file format you prefer.

Quickest Vagrant Tutoral Ever

Aug 29, 2011 Install Mac OS X Lion - This is the exact file downloaded from the App Store, and may or may not include personal information in the attached files. InstallESD.dmg - This is the file packaged within the above. It is the actual installer, and is identical to what anyone who has installed Lion uses. I have two Macs with me: one is my personal, the other my office has given. Instead of downloading the installer twice (10 GB), It would be great to download the copy and once use it to upgrade multiple devices (iMacs/Mac minis). I have tried to find the dmg file but I haven't been able to find it, instead I was redirected to the App Store. Nov 08, 2011 Here is how to download a full disk install version of lion. Thread starter johnhurley. Does it mean that 10.7.2 is a unified version of the OS X Lion for all mac products? With what johnhurley said in the first post, does it mean that an offline Lion installer via the InstallESD.dmg of the Lion downloaded from Mac App Store finally works. Jul 26, 2012 How to fix the problem where the SharedSupport folder is not present in the Contents of the DMG. Believe it or not, your DMG is already that 'InstallESD.dmg' file.

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.

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.

Cheetah 10.0	Puma 10.1	Jaguar 10.2
Panther 10.3	Tiger 10.4	Leopard 10.5
Snow Leopard 10.6	Lion 10.7	Mountain Lion 10.8
Mavericks 10.9	Yosemite 10.10	El Capitan 10.11
Sierra 10.12	High Sierra 10.13	Mojave 10.14
Catalina 10.15

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 o
