# VZMacPlatformConfiguration

The platform configuration for booting macOS on Apple silicon.

## Declaration

```swift
class VZMacPlatformConfiguration
```

## Mentioned in

Installing macOS on a Virtual Machine

## Overview

Overview When creating a VM, the hardwareModel and auxiliaryStorage depend on the restore image that you use to install macOS. To choose the hardware model, start from VZMacOSRestoreImage.mostFeaturefulSupportedConfiguration to get a supported configuration, then use its VZMacOSConfigurationRequirements.hardwareModel property to get the hardware model. Use the hardware model to set up VZMacPlatformConfiguration and to initialize a new auxiliary storage with init(creatingStorageAt:hardwareModel:options:). When you save a VM to disk and load it again, you must restore the hardwareModel, machineIdentifier and auxiliaryStorage properties to their original values. If you create multiple VMs from the same configuration, each should have a unique auxiliaryStorage and machineIdentifier.
