Launch VMware Workstation 12 Pro. Create a new virtual machine. In the Guest Operating System selection screen, you should now see:
If you see these options, Unlocker 208 has worked.
VMware Workstation natively blocks the ability to run macOS guests on non-Apple hardware. The Unlocker tool patches the VMware binary files (vmware-vmx.exe, etc.) to replace the "Apple SMC" (System Management Controller) check.
Version 2.0.8 specifically targeted the VMware 12 era, injecting the necessary code to trick the hypervisor into believing it was running on genuine Apple hardware.
VMware 12 Unlocker 208 for Mac OS remains a beloved relic in the virtualization community. It represents a time when running macOS on a Windows PC felt like a forbidden secret—unlocked by a few command-line scripts. While it is outdated and unsupported for modern macOS releases, it still works surprisingly well for older operating systems like OS X El Capitan, Sierra, and High Sierra.
If you have legacy software that requires macOS 10.12 or 10.13, and you have a Windows machine with VMware Workstation 12, this guide will help you resurrect that environment. For everyone else, treat this as a historical deep dive—or a stepping stone to newer unlockers.
Remember: Always keep your VMware Tools updated, backup your VMX file before editing, and respect the licensing terms of the software you virtualize.
Unlocking VMware 12 on Mac OS with Unlocker 208: A Step-by-Step Guide
VMware is a popular virtualization software that allows users to run multiple operating systems on a single machine. However, the macOS version of VMware has some limitations, such as not supporting macOS as a guest operating system out of the box. This is where Unlocker 208 comes in – a popular tool that unlocks VMware 12 on Mac OS, enabling users to run macOS as a virtual machine.
What is Unlocker 208?
Unlocker 208 is a patch file that modifies VMware 12's code, allowing it to bypass Apple's checks and run macOS as a guest operating system. The tool is specifically designed for Mac OS and works by patching the VMware 12 binary.

Unlocker 208 is a reliable tool for unlocking VMware 12 on Mac OS, allowing users to run macOS as a virtual machine. By following these steps, you should be able to successfully unlock VMware 12 and install macOS as a guest operating system.
In the late nights of the mid-2010s, the "Unlocker" wasn’t just a script—it was a skeleton key for the digital underground.
The year was 2015, and the virtualization community was hit with a roadblock. VMware Workstation 12 had just arrived, sleek and powerful, but it carried the same old corporate restriction: "Apple Mac OS X" was nowhere to be found in the guest OS menu unless you were running on expensive Apple hardware.
Enter Donk, the legendary developer behind the Unlocker 2.0.8 project.
In a quiet corner of the internet, the code was being perfected. The 2.0.8 release was the "silver bullet" for VMware 12. It didn't just ask the software to cooperate; it performed a surgical bypass. When a user ran that win-install.cmd or lnx-install.sh as an administrator, the script reached into the heart of the VMware binaries—specifically vmware-vmx.exe—and flipped the bits that checked for the "genuine" SMC (System Management Controller).
Suddenly, the greyed-out options turned white. The forbidden "Apple" logo appeared in the dropdown menu.
For thousands of developers who couldn't afford a $2,000 Mac but needed to test a single line of iOS code, Unlocker 2.0.8 was a revolution. It turned standard PCs into "Hackintosh" playgrounds, allowing the shimmering translucency of OS X El Capitan to breathe inside a Windows window.
It was a cat-and-mouse game of code. Every time VMware patched a hole, the Unlocker community found a new vein to tap. Version 2.0.8 remains a nostalgic milestone—the moment the walls between hardware ecosystems felt just a little bit thinner.
Running macOS on non-Apple hardware has long been a challenge due to software locks. One of the most effective tools for bypassing these restrictions on older versions of VMware is Unlocker 2.0.8 (and its successor, v2.1).
This blog post provides an informative look at what the unlocker does, how to use it, and important considerations for your virtualization project. The Magic Key: Understanding VMware Unlocker 2.0.8
By default, VMware Workstation and Player on Windows or Linux do not show "Apple Mac OS X" as an option when creating a new Virtual Machine. This isn't because the software can't run macOS, but because VMware actively disables this feature to comply with Apple’s End User License Agreement (EULA).
What does the Unlocker actually do?The tool does not change the core code of VMware's executable files. Instead, it patches: Launch VMware Workstation 12 Pro
Data Tables: It modifies the virtual SMC (System Management Controller) tables so macOS can boot.
Guest Host Tables: It patches vmwarebase.dll (Windows) or libvmwarebase.so (Linux) to reveal the "Apple Mac OS X" option in the OS selection menu.
VMware Tools: It often includes or downloads the darwin.iso file, which is necessary for high-resolution graphics and smooth mouse performance within the guest macOS. Installation Guide for VMware Workstation 12

VMware Workstation 12 with macOS, you must use a patching tool like Unlocker 2.0.8
because VMware does not natively support macOS guests on non-Apple hardware. 🛠️ Step 1: Prerequisites
Before starting, ensure your system meets these requirements: Virtualization Enabled
: Enable "Intel VT-x" or "AMD-V" in your computer's BIOS/UEFI. VMware Workstation 12 : Ensure it is installed but completely closed (including background services). macOS Image : Have a macOS file (e.g., El Capitan, Sierra) ready. 🔓 Step 2: Running Unlocker 2.0.8 The Unlocker tool patches VMware files ( vmware-vmx.exe vmwarebase.dll ) to reveal the "Apple Mac OS X" guest option. Download & Extract
: Download the Unlocker 2.0.8 archive and extract all files to a folder on your desktop. Locate Script : Find the file named win-install.cmd Run as Administrator : Right-click win-install.cmd and select Run as Administrator Wait for Completion
: A command prompt will open, stop VMware services, apply patches, and restart services. It will close automatically when finished. : Open VMware Workstation. Click Create a New Virtual Machine . If the patch worked, Apple Mac OS X will now appear in the Guest OS list. 🖥️ Step 3: Create the Virtual Machine

Recommendation: If you are running a legacy system with VMware Workstation 12 specifically, Unlocker 2.0.8 is a piece of history that works perfectly. However, for any modern setup looking to run macOS, you should skip version 2.0.8 entirely and seek out the modern Unlocker 3 or Auto-Unlocker projects.
Title: Unlocking macOS on VMware Workstation 12: A Retrospective on Unlocker 208
If you are a virtualization enthusiast or an IT professional who has been in the industry for a few years, you have likely encountered the desire to run macOS on your Windows or Linux PC.
Historically, VMware Workstation has been the go-to solution for running multiple operating systems. However, out of the box, VMware does not support running macOS as a guest operating system on non-Apple hardware. This is where the legendary "VMware Unlocker" comes in.
In this post, we are taking a retro look at Unlocker version 2.0.8 for VMware Workstation 12, exploring what it was, why it was necessary, and the legacy it left behind.
Don't use VMware 12 for macOS. Instead:
Would you like a guide for a modern, more functional setup instead?
The VMware Unlocker 2.0.8 is a legacy patch designed specifically to enable Apple macOS support in VMware Workstation 11/12 and VMware Player 7/12 on non-Apple hardware. While originally released to support guest versions like OS X El Capitan and Yosemite, it has largely been superseded by newer versions like Unlocker 3.0 or the DrDonk Unlocker for more recent macOS versions. Core Functionality
Unlocks Guest OS Options: Patches vmwarebase.dll (on Windows) or libvmwarebase.so (on Linux) to allow users to select "Apple Mac OS X" during virtual machine creation.
Enables Booting: Modifies vmware-vmx executables to allow macOS guests to boot by providing a virtual SMC (System Management Controller).
Provides VMware Tools: Includes the darwin.iso image required for installing drivers (keyboard, mouse, and display resolution) within the macOS guest. Installation Steps for VMware 12
The process involves running script files as an administrator while VMware services are completely stopped. DrDonk/unlocker: VMware macOS utilities - GitHub
