-## One-key semi-automatic installer of macOS Mojave 10.14 on VirtualBox

-The "one key" is enter, which has to be pressed whenever the virtual machine is ready for the next command. (Contrary to the script's name, the user has to use more than one key! There is one instance when the right control key or "host key" is used to release the mouse from the virtual machine, and a couple of instances where the user has to choose [y]es or [n]o!)

-The goal of the script is to allow for a very easy installation without any closed-source additions or extra bootloaders.
+## Push-button installer of macOS on VirtualBox

-Tested on Cygwin and WSL, should work on most Linux distros.
+[`macos-guest-virtualbox.sh`](https://raw.githubusercontent.com/myspaghetti/macos-guest-virtualbox/master/macos-guest-virtualbox.sh) is a Bash script that creates a macOS virtual machine guest on VirtualBox with unmodified macOS installation files downloaded directly from Apple servers.

-## iCloud and iMessage connectivity
+A default install only requires the user to sit patiently and, less than ten times, press enter when prompted by the script, without interacting with the virtual machine.

-iCloud and iMessage and other connected Apple services require a valid device serial number. Set it before the installation by replacing `NOTAVALIDSN0` with a valid serial number, or after the installation with `VBoxManage setextradata "${vmname}" "VBoxInternal/Devices/efi/0/Config/DmiSystemSerial" "${serialnumber}"`. An invalid serial number that matches the correct structure for the device name and board ID might work, too.
+Tested on `bash` and `zsh` on [Cygwin](https://cygwin.com/install.html). Works on macOS, CentOS 7, and Windows. Should work on most modern Linux distros.
+
+macOS Catalina (10.15), Mojave (10.14), and High Sierra (10.13) currently supported.
+
+## Documentation
+
+Documentation can be viewed by executing the command `./macos-guest-virtualbox.sh documentation`
+
+The majority of the script is either documentation, comments, or actionable error messages, which should make the script straightforward to inspect and understand.
+
+## iCloud and iMessage connectivity and NVRAM
+
+iCloud, iMessage, and other connected Apple services require a valid device name and serial number, board ID and serial number, and other genuine (or genuine-like) Apple parameters. These can be set in EFI and NVRAM by editing the script. See the [documentation command](#documentation) for further information.

 ## Storage size

-The script assigns the minimum required storage size for the installation. After the installation is complete, the virtual disk image may be increased through VirtualBox, and then the macOS system APFS container size may be increased. Inside the virtual machine run `sudo diskutil repairDisk disk0` and then from Disk Utility delete the "Free space" partition, allowing the system APFS container to take up the available space.
+The script by default assigns a target virtual disk storage size of 80GB, which is populated to about 25GB on the host on initial installation. After the installation is complete, the storage size may be increased. See the [documentation command](#documentation) for further information.
+
+## Primary display resolution
+
+The following primary display resolutions are supported by macOS on VirtualBox: `5120x2880` `2880x1800` `2560x1600` `2560x1440` `1920x1200` `1600x1200` `1680x1050` `1440x900` `1280x800` `1024x768` `640x480`. See the [documentation command](#documentation) for further information.

 ## Unsupported features

-Developing and maintaining VirtualBox or macOS features is beyond the scope of this script. Some features may behave unexpectedly, such as USB device support, [audio support](https://github.com/chris1111/VoodooHDA-2.9.2-Clover-V13/releases), and other features.
+Developing and maintaining VirtualBox or macOS features is beyond the scope of this script. Some features may behave unexpectedly, such as USB device support, audio support, FileVault boot password prompt support, and other features.
+
+### CPU compatibility
+
+macOS guests on VirtualBox are incompatible with some CPU models. If the guest macOS boot process hangs on “LoadKernelFromStream”, “EndRandomSeed”, or "EXITBS", see the [documentation command](#documentation) regarding VirtualBox CPU profiles and [CPUID settings](https://www.virtualbox.org/manual/ch08.html#vboxmanage-modifyvm-teleport). Some CPU models released in 2020 and later may fail to start or complete the installer, and may require manually adjusting the CPUID settings.
+
+### Upgrading to Big Sur and Monterey 
+
+The virtual machine may be upgraded to the latest macOS Big Sur (11) and macOS Monterey (12) versions through Software Update. Big Sur may be installed in-place. Monterey may require attaching another volume to the virtual machine and selecting the volume as the installation target, otherwise the upgrade is prone to failing and entering a boot loop.
+
+### Performance and deployment
+
+After successfully creating a working macOS virtual machine, consider importing it into more performant virtualization software, or packaging it for configuration management platforms for automated deployment. These virtualization and deployment applications require additional configuration that is beyond the scope of the script.
+
+QEMU with KVM is capable of providing virtual machine hardware passthrough for near-native performance. QEMU supports the `VMDK` virtual disk image storage format, which can be configured to be created by the script. See the [documentation command](#documentation) for further information. QEMU and KVM require additional configuration that is beyond the scope of the script.
+
+#### VirtualBox Native Execution Manager (NEM)
+
+The VirtualBox Native Execution Manager (NEM) is an experimental VirtualBox feature. [VirtualBox uses NEM when access to VT-x and AMD-V is blocked by virtualization software or execution protection features such as Hyper-V, WSL2, WSLg, Windows Sandbox, memory integrity protection, Application Guard, Credential Guard, Device Guard, and other features and software.](https://docs.microsoft.com/en-us/troubleshoot/windows-client/application-management/virtualization-apps-not-work-with-hyper-v) macOS and the macOS installer have memory corruption issues under NEM virtualization. The script checks for NEM and exits with an error message if it is detected.
+
+[VirtualBox can run on WSL2 and WSLg with some kernel module compilation](https://github.com/myspaghetti/macos-virtualbox/issues/525), though performance is extremely low. At the point that kernel module compilation is required, it's preferable to use QEMU/KVM. QEMU/KVM on WSL2 and WSLg is orders of magnitude faster than VirtualBox. WSL2, WSLg, QEMU, and KVM require additional configuration that is beyond the scope of the script.
+
+### Bootloaders
+
+The macOS VirtualBox guest is loaded without extra bootloaders, but it is compatible with [OpenCore](https://github.com/acidanthera/OpenCorePkg/releases). OpenCore requires additional configuration that is beyond the scope of  the script.
+
+### Audio
+
+macOS may not support any built-in VirtualBox audio controllers. The bootloader [OpenCore](https://github.com/acidanthera/OpenCorePkg/releases) may be able to load open-source or built-in audio drivers in VirtualBox, providing the configuration for STAC9221 (Intel HD Audio) or SigmaTel STAC9700,83,84 (ICH AC97) is available.
+
+### Display scaling
+
+VirtualBox does not supply an EDID for its virtual display, and macOS does not enable display scaling (high PPI) without an EDID. The bootloader OpenCore can [inject an EDID](https://github.com/acidanthera/WhateverGreen/blob/master/Manual/FAQ.IntelHD.en.md#edid) which enables display scaling.
+
+### FileVault
+
+The VirtualBox EFI implementation does not properly load the FileVault full disk encryption password prompt upon boot. The bootloader [OpenCore](https://github.com/acidanthera/OpenCorePkg/releases/tag/0.6.9) is able to load the password prompt with the parameter `ProvideConsoleGop` set to `true`. See sample [config.plist](https://github.com/myspaghetti/macos-virtualbox/files/6600860/config.plist.txt)
