Setup Mac OS within Windows 10 using VirtualBox

• The below steps work for Big Sur
• We tried for Monterey, but not working yet, will update if any progress

• Download and install VirtualBox as well as the corresponding VirtualBox Extension Pack for Windows 10 via: https://www.virtualbox.org/wiki/Downloads

• Obtain the VirtualBOx ISO images for the macOS version we plan to install:

  • Generated from another Mac machine
  • Search Google

• Luanch the VirtualBox and install the macOS ISO images as below:

  • 

  • 

  Make sure to note the Name you input, which will be needed later on. We recommend to allocate at least half of the total Memory size for the VM.

  • 

  Note we recommend to set at least 200GB hard disk size for the virtual macOS.

  • The initial virtual machine (by the Name you input above) should be setup by now, and we can continue with more Settings:

    • 

    • 

    For System: - Remove "Floppy" as we don't need it - More importantly, we shall allocate no more than half of the "Processor" (CPU) we have in total, to maintain balanced performance between the host Windows 10 and the virtual Mac.

    • 

    Note to set the Display memory to maximum

    • 

    Note to select the corresponding ISO image we have obtained.

    • 

• Click OK once above is all done, and EXIT from the VirtualBox completely. This is important before we proceed with the below steps.

• Obtain the VirtualBox code for the macOS version we plan to install (search Google):

  • VirtualBox_Code_BigSur.txt
  • VirtualBox_Code_Monterey.txt

• Execute the above VirtualBox code via the command prompt of Windows 10 (as Administrator)

• Luanch the VirtualBox again, select the MacOS VM we setup and click Start:

  • After initial loading
  • Go to Disk Utility and Erase the VBOX HARDDISK Media, for a clean install later on. You can pick a name for the new hard disk as you like, and go with Mac OS Extended format when asked.
  • Return back to the menu and go for **Install macOS Monterey". Follow the prompts and the process shall take about 30 mins.

• Obtain the VirtualBox code for config the screen resolution after the macOS VM setup (search Google):

  • VirtualBox_Code_macOS_Screen_Resolution.txt
  • Exit the VirtualBox manager, and execute the code via command prompt of Windows 10.

• Once the virtual MacOS completely setup, you may find issue trying to login your Apple ID. This can be solved by:

  • Within the VM MacOS, go for system --> Network --> Advanced
  • Click + on the DNS entries and input 8.8.4.4
  • You should be able to then log in your apple ID via the App Store (Not via the Settings)

• Such VM setup is supposed to provide a MacOS for user to develop iOS app without a Windows 10 machine
• With Big Sur installed, the corresponding XCode version will be relatively older
