While the tool is highly effective, it exists in a legal and technical gray area. Since it modifies proprietary code, it violates the terms of service of both VMware and Apple. Furthermore, virtualization often lacks hardware acceleration

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.

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.

Without Unlocker 208, VMware 12 simply throws an error: "You cannot install this operating system on this hardware." With the patch applied, macOS Sierra, High Sierra, Mojave, and even Catalina (with tweaks) could run on standard Intel-based PCs.
