Does MacOS Work on a PC? Step by Step to Installation

Are you excited about the new version of MacOS Big Sur? Apple made big changes to its flagship operating system, which is sure to make a splash when it debuts this fall. If you’re like us, you are itching to download the public beta and dive in.
The problem is, you don’t have a Mac. That is not as big an obstacle as you think. Read on to follow this step-by-step guide to installing MacOS Catalina on a compatible PC.
Background Information
When you install the MacOS Operating System on a PC, you create a Hackintosh. A Hackintosh is a portmanteau of “hack” and “Macintosh,” and there is a thriving community of hobbyists who make MacOS work on a variety of systems. If you have a problem with your Hackintosh, you can find someone to help you.
Before you do anything, you’ll want to take a look at the Big Sur system requirements. If your PC doesn’t meet them, this will save you time and effort. Remember, you still have time to get a fresh laptop or build yourself a new PC specifically for Big Sur.
The only downside to the method outlined here is you need a functioning Mac to get started. It doesn’t have to be new, just newer than a 2012 model MacBook. It can even be a version of the MacOS operating system run on a virtual machine!
The point is, you need the App Store to get the first component, the install files for MacOS. Then you need a couple of programs to make a bootable USB drive that will work on your Intel PC.
Setting up the USB Boot Disk
Make sure your PC meets the MacOS system requirements, then download the install files for MacOS Catalina. This will get you the latest version of MacOS. It should be sitting in the Applications folder.
Register and Download Unibeast. You need to download this and the related app MultiBeast on a Mac. They won’t work if you download them and copy them over to a Mac.
Install UniBeast on the Mac. This program is what allows you to create the USB boot drive.
Plug the USB drive you want to use to install MacOS. Launch Disk Utility, open the Partition tab, and get rid of any extra partitions on the drive. Then make sure the drive format is Mac OS Extended (Journaled) and click “Apply”.
If the Scheme is listed as anything other than “GUID Partition Map” click the Erase tab, change it, and press Erase. Otherwise, you’re good and can move on.
Installing UniBeast
Launch UniBeast. The first window lets you choose the installer destination. Click on the USB drive you just formatted.
Click “Continue” in UniBeast until it asks you which OS you wish to install. In this case, you’ll want to pick Catalina. Click “Next”.
Next, you need to choose between the two main boot modes, UEFI and Legacy. In most cases, choose UEFI. If your motherboard is an older model and uses BIOS, then choose Legacy.
After that, you’ll be asked to choose your PC’s graphics card. If you have a modern computer with a newer Intel CPU, then you can skip this step. Otherwise, choose whichever option best describes your PC’s graphics card.
Click “Continue” and UniBeast will begin installing on your chosen USB drive. Be patient with this step, as it can take up to an hour.
When UniBeast is done, you can then downloa MltiBeast and drop it onto the USB drive. MultiBeast will allow you to configure the installation on your PC.
Configuring the UEFI
This part is a bit tricky, but if you follow along, you should be fine! On the PC you plan to install MacOS on, follow these steps:
