Prerequisites: macOS Catalina on VMware

Before we start the installation of macOS Catalina on VMware, make sure you have these essentials ready:

1. A Compatible Windows PC:
   • CPU: A 64-bit Intel or AMD processor (Intel Core i5/i7/i9 or AMD Ryzen 5/7/9 recommended). Crucially, your CPU must support hardware virtualization (Intel VT-x or AMD-V). (Check your BIOS/UEFI settings – often found under “Security” or “Advanced CPU Settings”).
   • RAM: Minimum 8 GB. 16 GB or more is strongly recommended for smooth performance, as your host Windows and the macOS VM will share this.
   • Storage: At least 50 GB of free space on a reasonably fast drive (SSD highly recommended). Catalina itself needs ~20GB, plus space for apps and files.
   • Windows OS: Windows 10 or 11 (64-bit).
2. VMware Workstation Pro: Download the latest version from our website- Download VMware Workstation Pro 25H2 for Windows
3. macOS Unlocker for VMware: This essential tool patches VMware to allow macOS as a guest OS option. Download the latest version compatible with your VMware Workstation from our website- Download macOS Unlocker
4. macOS Catalina ISO file: You need the macOS Catalina Image file- Download macOS Catalina ISO
5. Patience and Time: The installation process can take 30-60 minutes, depending on your hardware.

Step-by-Step Guide: Installing macOS Catalina on VMware

Important Note: Creating and running a macOS VM on non-Apple hardware technically violates Apple's End User License Agreement (EULA). This guide is intended for educational purposes, testing, and development, where you have legitimate access to macOS software.

Step 1: Install VMware Workstation Pro

1. Run the downloaded VMware Workstation Pro installer.
2. Follow the on-screen prompts (accept the license agreement, choose installation location, etc.).
3. Complete the installation and restart your PC if required.

Step 2: Apply the macOS Unlocker

1. Crucial: Make sure none of the VMware services are running:
   • Open Task Manager (Ctrl+Shift+Esc).
   • Go to the “Services” tab.
   • Find any service starting with “VMware”, right-click it, and select “Stop”. Do this for all VMware services.

2. Extract the downloaded macOS Unlocker ZIP file.
3. Right-click the win-install.cmd file (or similarly named main script) and select “Run as administrator”.

4. A command prompt window will open. Let it run completely. It will patch the necessary VMware files to recognize macOS.
5. Once it finishes, close the window.

Step 3: Create the macOS Catalina Virtual Machine

1. Launch VMware Workstation Pro.
2. Click “Create a New Virtual Machine” or go to File > New Virtual Machine.

3. Select “Typical (recommended)” and click “Next“.

4. Installer disc image file (iso): Click “Browse…” and navigate to your downloaded macOS Catalina ISO file. Select it. Click “Next“.

5. Guest Operating System: VMware should now recognize it as “Apple macOS“. Select the version “macOS 10.15” from the dropdown. Click “Next“.

6. Name the Virtual Machine: Give it a clear name (e.g., “macOS Catalina“). Choose where to store the VM files (ensure enough space!). Click “Next“.

7. Disk Capacity: Set the maximum disk size. Recommendation: 40-80 GB (select “Store virtual disk as a single file” for better performance). Click “Next“.

7. Ready to Create: Review your settings. Crucial: Click “Customize Hardware…” before clicking Finish.

Step 4: Configure Virtual Machine Hardware Settings

1. In the Hardware Customization window:

• Memory: Allocate RAM. Minimum 4096 MB (4 GB). Strongly Recommended: 8192 MB (8 GB). Don’t allocate all your RAM; leave enough for Windows.
• Processors:
  • Number of cores: 2 or more (e.g., 2 cores, 2 threads if your CPU has hyperthreading). Don’t allocate all cores.
  • Check “Virtualize Intel VT-x/EPT or AMD-V/RVI”.

• Hard Disk (SCSI): Ensure size is correct. Consider changing “Virtual device node” to “SATA 0:0” if you encounter boot issues later (common fix). Leave other settings default.
• USB Controller: Set USB Compatibility to “USB 3.1” (or 3.0/3.2, depending on the options) for improved performance if your host supports it.
• Display: Check “Accelerate 3D graphics”. Increase Video Memory to the maximum available (e.g., 2GB or 4GB) for smoother graphics.
• Network Adapter: “Bridged” (connects VM directly to your network like a physical device) or “NAT” (shares your host’s IP) are usually fine.

2. Click “Close” on the Hardware Settings window, then click “Finish” on the main VM creation window. VMware will create the VM files.

Step 5: Modify the VMX File (Essential Fix)

1. Locate the VM’s primary configuration file (ends in .vmx). It’s in the folder you specified when naming the VM (Step 3.6). (C:\Users\gupta\Documents\Virtual Machines\)

2. Right-click the .vmx file, select “Open with”, and choose Notepad or a text editor.
3. Add these lines at the VERY END of the file: These lines help macOS correctly identify the virtual CPU.

smc.version = "0"

4. Find the line: firmware = "efi" and change it to firmware = "efi-secure". This is crucial for Catalina.
5. Save the .vmx file and close the editor.

If you have an AMD processor, use these VMX codes: VMX Codes for AMD & INTEL

Step 6: Install macOS Catalina on VMware

1. In VMware Workstation, ensure that your new macOS VM is selected.
2. Click “Power on this virtual machine”. The VM will boot.
3. Apple Logo & Progress Bar: The VM should now load the macOS Recovery environment (this takes a few minutes). You’ll see the Apple logo and progress bar.

4. macOS Utilities: Select your language and click the arrow.

5. Disk Utility: Before installing, we need to format the main virtual disk.
   • Select “Disk Utility” > “Continue”.
   • In the sidebar, select the large VMware Virtual SATA drive (usually around 40-80GB, named “VMware Virtual SATA Hard Drive Media” or similar). DO NOT select the small 1GB drive.
   • Click “Erase”.
   • Set Name: techrechard.com.
   • Format: macOS Extended.
   • Scheme: GUID Partition Map.
   • Click “Erase”. Confirm.
   • Close Disk Utility when done.

6. Install macOS: In the Utilities menu, select “Install macOS” and then click “Continue”.

7. Follow the on-screen prompts:
   • Agree to the license agreement.
   • Select the Destination: Choose “techrechard.com HD”. Click “Install”.

8. Installation: The process will begin. It involves multiple reboots. Crucial: During reboots, if you get stuck at the VMware boot loader:
   • Manually select the “Macintosh HD” (your main APFS volume) to boot from. Do NOT select the small installer helper disk again after the initial boot.
   • Be patient; reboots within the macOS installer can take longer than usual.

9. Setup Assistant: After installation completes, the VM will reboot into the macOS Setup Assistant.
   • Select your region, language, etc.
   • Skip Signing in with Apple ID: For simplicity (especially testing), choose “Set Up Later” and “Don’t Sign In”.
   • Create a local user account (username, password).
   • Complete the setup (time zone, analytics preferences, etc.).

10. Welcome to macOS Catalina! Your desktop should appear.

Step 7: Post-Installation & VMware Tools (Enhancing Usability)

After successfully installing macOS Catalina on VMware, you need to perform the following:

1. Install VMware Tools (Essential for Performance): This provides graphics acceleration, better resolution, mouse integration, shared folders, and clipboard sharing.

• In the VMware menu bar (at the top of your Windows screen, not inside the VM), go to VM > Install VMware Tools.

• Now, you will see this error. Simply click on the link mentioned in the pop-up, and the file will be downloaded automatically.

• Save the file to your desktop. The file will be darwin.iso.

• Close your Virtual Machine and go to the Settings of your macOS Catalina VM.

• Click on Add and then select CD/DVD drive.

• Select Use ISO Image and attach the darwin.iso you downloaded above.

• Restart your virtual machine.

• Double-click the “VMware Tools” package (.pkg file) inside the mounted disk.

• Follow the installer prompts (Continue, Install, enter your macOS user password). Accept any system extension warnings if prompted (go to System Preferences > Security & Privacy > Allow).

• Wait for a while until you see that the installation is successful.

• Reboot the VM by clicking on Restart.

2. Adjust Display Resolution: After reboot with VMware Tools, go to System Preferences > Displays and choose a more suitable resolution for your screen.

• From the top VMware menu, click on the Fullscreen icon to make your windows full screen.

• You can exit full screen at any time from the top menu.

2. (Optional) Enable File Sharing: In VMware VM Settings (VM > Settings > Options):
   • Select “Shared Folders”.
   • Set to “Always enabled”.
   • Click “Add…” to browse and add a folder from your Windows host to share with macOS.
   • Inside macOS, shared folders appear under /Volumes/VMware Shared Folders/.
