# minimumSupportedMemorySize

The minimum supported memory size for this configuration.

```
var minimumSupportedMemorySize: UInt64 { get }
```

## Discussion

This property specifies the minimum amount of memory required by the associated macOS configuration.

You associate a [`VZMacOSConfigurationRequirements`](/documentation/Virtualization/VZMacOSConfigurationRequirements) with a specific [`VZMacOSRestoreImage`](/documentation/Virtualization/VZMacOSRestoreImage) object, which results in a specific macOS configuration.

Installing or running the associated configuration of macOS on a VM with less than this amount of memory results in undefined behavior.
