This paper outlines the technical process and considerations for creating a macOS Virtual Machine (VM) image for use within VMware Workstation or Fusion.
Technical White Paper: Creating and Configuring a macOS VMware Image 1. Executive Summary
Running macOS on non-Apple hardware (Hackintosh) or as a virtual machine on a Windows/Linux host requires specialized configuration. This paper details the necessary steps to create a bootable macOS ISO, configure VMware, and optimize the environment. 2. Prerequisites Host System:
A Windows or Linux PC with a capable CPU (Intel/AMD) and at least 16GB RAM. VMware Workstation Player/Pro (17.5+ recommended) or VMware Fusion Pro VMware Unlocker: A tool to patch VMware to allow macOS guest OS selection. macOS Installer:
A DMG or ISO file of the desired macOS version (e.g., Sonoma, Ventura, Monterey). 3. Creating the macOS ISO/VMDK Image VMware typically requires a file to install a guest operating system. Obtain Installer: mac os vmware image
Download the macOS installer from the Apple App Store on an existing Mac. Convert to ISO: Use terminal commands on a Mac to convert the InstallAssistant.pkg to a bootable ISO. Alternative Method (Virtual Disk): Use tools like to convert a BaseSystem.dmg (VMware Virtual Disk) format for immediate installation. 4. VMware Configuration Steps
Note: Run the VMware Unlocker before creating the VM to ensure "Apple Mac OS X" is a selectable OS type. Open VMware and select "Create a New Virtual Machine." Configuration: Choose "Custom" for advanced configuration. OS Selection:
Select "Apple Mac OS X" and choose the version matching your ISO (e.g., macOS 14 or 15). Hardware Optimization: Processor: Allocate at least 2 cores. Allocate 4GB or more (8GB recommended).
Create a new virtual disk (SCSI or SATA) of at least 40GB. Choose "Store virtual disk as a single file" for better performance, or split it if necessary. Assign ISO: This paper outlines the technical process and considerations
Point the CD/DVD drive to the previously created macOS ISO file. 5. Editing the VMX File
To enable proper booting, the virtual machine's configuration file ( ) must be edited. Navigate to the folder where the VM is saved. file with a text editor (e.g., Notepad).
Add the following line to the end of the file to fix potential booting issues: smc.version = "0" Depending on the host CPU, you may need to add: cpuid.0.eax = "0000:0000:0000:0000:0000:0000:0000:1011" cpuid.0.ebx = "0111:0101:0110:1110:0110:0101:0100:0111" cpuid.0.ecx = "0110:1100:0110:0101:0111:0100:0110:1110" cpuid.0.edx = "0100:1001:0110:0101:0110:1110:0110:1001" 6. Installing and Optimizing macOS
Start the VM, enter Disk Utility, erase the virtual disk (as APFS), and run the "Install macOS" process. VMware Tools: Post-installation steps
Install VMware Tools (darwin.iso) within the guest OS to improve graphics, resolution, and mouse performance. Optimize Performance:
If the guest is slow, assign more resources, ensure VT-x/AMD-V is enabled in the host BIOS, and minimize background processes on the host. 7. Legal and Compliance Notice Running macOS on non-Apple hardware breaches the Apple End User License Agreement (EULA)
