Download & Install macOS Unlocker for VMware Workstation in Windows 10, 8.1/7

If you want to use macOS or earlier versions on Intel-based Windows OS computers by VMware workstation or VM player, “macOS unlocker” is a compulsory utility. This unlocker utility replaces few VMware program files and patches them to install and run macOS and older versions as virtual machines on Windows OS. Here is the download link of working unlocker for VMware Workstation version 11 to 15 (all tested by me) on Windows 10, 8.1 64 bit and Windows 7 32 bit physical computers.

UPDATE (20-09-2019) This post was originally published back in the year 2011 and had been updated several times to match the latest versions and requirements. It is now again getting updated for latest version of macOS 10.15 Catalina and Unlocker version 3.0.2.

VMware Unlocker

I have already published few guides about installing Mavericks, Mountain Lion and Lion OS X on VMware workstation by using this unlocker.

Download Link of Latest Unlocker for macOS, VMware Workstation 11-15 versions

Download the DrDonk unlocker from the developer’s site here.

It has been tested against Workstation 11-15 versions and VMware player 7,12,14 and 15. If you have the older version of unlocker installed, you must uninstall it before installing the latest version. Failure to do this may hamper your VMware workstation files and program.

Install macOS Unlocker on Windows 10 for VMware Workstation 11/12/14/15

1) Since this tool will be changing and updating the binary files on VMware workstation, it is always good practice to backup the VMware program folder before running the unlocker.

2) After downloading the zip file, extract it.

3) If you have the previous version of unlocker, you must uninstall it first. To do that, right-click on the uninstallation script and execute it as administrator.

Uninstall Unlocker

Note: VMware workstation or player must be completely switched off before running this script.

4) Close any working Vivrutla machines and VMware program. Execute the installation script as administrator.

5) It will patch some files and even download the VMware tools for macOS guest machines. Let it do and complete.

Running Unlocker

6) Now you must see the difference in the guest OS support. Without the patch, you can’t create any macOS VMs because they were not listed as below.

No MacOS Support

After the patch, now it should appear as below.

MacOS Support -Install macOS Unlocker for VMware Workstation

I’m just a tester of this utility. Full credits should go to the developer who produced a great tool. This particular macOS unlocker works on Intel processor Windows and Linux computers only. AMD is not supported yet.

If you are having the older version of VMware workstation, earlier than version 11, then you need the older version of unlocker.

working 10.11 on Windows 10 with Unlocker

Here is working El Capitan 10.11 on Windows 10 with VMware workstation 15. I will keep publishing guides based on this unlocker.

After patching the VMware workstation with this unlocker then upgrade the VMware to any major versions, the patch is no longer valid. You may not be able to run or create macOS VMs anymore. You need to run the latest unlocker (which has the support of the VMware version you have) to get the macOS virtual machine support again.

Older versions of Unlockers (Link below)

a) Visit the official site to download unlocker 2.0.7 (free registration required). This works for VMware workstation 11.

b) For VMware version 10, 9, 8 and 7, you need to get the unlocker ver 1.0.3.

Here is the link to download.

In the older versions of unlockers, you may find the different set of files.

Right-click on install.cmd file and select Run as administrator option as shown below. ( or you can start the command prompt as administrator in Windows 7 computer and execute install.cmd from command prompt)

right click and patch

Here is the working Mountain Lion OS X 10.8 in VMware workstation 9 with Windows 7 32 bit host after running unlocker.

With these all, you must have a clear idea of downloading and installing macOS unlocker on Windows 10 and older versions. If your VMware workstation or VM player is older, then we have mentioned the download links for supported Unlockers.

  7. Anything in the works for VMware 12.1? The current locker doesn’t seem to work, unless, maybe, on a clean install of 12.1, which I haven’t tried – I have been re-applying the unlock after the update of VMware.
    …and MAYBE I’ve even applied the unlock only once after an update – not too sure.
    Any comments appreciated.

  8. I have workstation 12 with unlocker 2.0.8 on Win 10, trying to install Yosemite VM. It is stuck in the Apple Logo screen with black BG, half way through the bar. Anyone can help?

    • Yes you can when chosing your iso file in the corner instead of iso files click all files then double click your dmg.

  9. Thank you so much! I was stressing out over how my Mac OS X Yosemite in VMWare wouldn’t load.

  10. Hi I am on Windows 7 and have VMware workstation 10. Unlocker 2.8 didn’t work so I downloaded 1.3 version, which worked and VMware now shows Mac OS option but it doesn’t show 10.11 version but shows till 10.9

    Will I have to use VMware 11 or 12 for El Capitan.

    Please advise.


  11. Hi. I have runned OS X Guest successfully on Windows.
    Now I want to use the same virtual machine on Ubuntu 16.04.
    Is there any unlocker for the Linux version of VMware Workstation 12 Player?

  12. That is a very good how-to article, I always wanted to experience the limitations of Mac OS and find out why those limitations make it so special without spending an awful lot on a mac for no reason.
    Virtualization is one of those things which pushes the power of a single machine to its maximum utilization and you can test out many programs and most important of all cybersecurity with wrecking the machine.

  13. Also not working on WMware Workstation 15.5 Pro 15.5.0 build-14665864 and Windows 10 1909 (OS build 18363.418)

  14. I am having the same issue as SAAS – it appears that the “Before” and “After” keys are identical and the “vmwarebase.dll” is not being patched or updated at all.

    I am using the same versions of VMware Workstation Pro and Windows 10.
