Can't Open Basesystem.dmg Hackintosh

  • Open your terminal and change directory to where the BaseSystem.dmg file is in my case: cd Desktop Then run dmg2img BaseSystem.dmg base.iso it will convert the the dmg file to iso file named base.iso Open Disks AKA 'Gnome-Disk-Disk-Utility' and drag base.iso to it and hit start restoring. This will take a wile.
  • There is actually a hidden file called 'BaseSystem.dmg' in the root directory of the 'OS X Install ESD' volume that was just mounted. To show the hidden file, you can change the system settings to show all hidden files or just open it using the Terminal which is what I did.

In this post I’m gonna show you how to make Hackintosh Bootable USB Drive on Windows without Distro.Without distro means we gonna make a Hackintosh Bootable U S Drive for Vanilla Installation method. This method works on Mac OS X Yosemite, El Capitan, and Mac OS Sierra. As I’ve tried all that OS myself on my low budget Hackintosh PC.

Yosemite and later used a built in program called createinstallmedia to automagically make a USB stick. It is possible to create a bootable USB stick without this program.

You'll need an 8GB USB stick and either the Install Mac OS X Lion.app or InstallESD.dmg or BaseInstall.dmg.

Open Terminal, you'll need it in most of this tutorial.

We're going to need to start by getting to the actual installation disk image.

Step 1a - Install Mac OS X Lion.app

Mine is in Applications, but you can put it anywhere for this.

In Terminal:

Should output something like: ./Contents/SharedSupport/InstallESD.dmg

In Terminal:

Step 1b - BaseInstall.dmg

Open your BaseInstall.dmg file.

In Terminal:

From here you should see something like OS X Install ESD or something like that, cd into that path.

It should show something like: ./BaseSystem.dmg

In Terminal:

Step 1c - InstallESD.dmg

If you just have an InstallESD.dmg or BaseSystem.dmg file, you should just open them.

Look in Volumes you should see something like OS X Base System, remember whatever it shows.

Step 2 - Find Your Install Disk

Should display something like:

Take note of the disk, for example mine is /dev/disk3s2.

Step 3 - Preparing Your USB Stick

Insert your USB Stick.

In Terminal:

Hackintosh

Should display something like something else may appear depending on your stick.

Take note of the disk, in my case /dev/disk4.

Partition it.

Should output something like this:

Here you want to take note of the Initialized line, specifically your disk, mine is /dev/rdisk4s2.

Step 4 - Restore from the DMG File

WARNING IF YOU PUT THE WRONG DISKS IN HERE YOU CAN WIPE YOUR MACHINE

The source should be the disk from Step 2, the target should be the disk from Step 3

This should prompt you for your login password and display:

Step 5 - Make Bootable

In Volumes now you should have your USB stick and original installer and possibly other mounts.

I do a force unmount here, this will not unmount your system disk(s).

Remove and re-insert your USB Stick now.

Should show OS X Base System or OS X Install ESD.

Should output something like:

You should be able to Eject your stick and boot from it now.
