# Hypervisor updates Learn about important changes to Hypervisor. ## Overview Browse notable changes in . ## June 2025 - Support configuration of the intermediate physical address (IPA) memory granularity of a virtual machine (VM). This capability enables more efficient use of memory and allows for granularity sizes down to 4 KB, which is useful for certain specialized device drivers. ## June 2024 - Build your own VM solutions with added support for nested virtualization in Apple silicon chips, and enable a Hypervisor to run inside another VM. Nested virtualization capabilities on a Mac with Apple silicon use a new exception level (EL), EL2, which the framework enables though several new methods, including , and a number of enumeration constants that describe ARM system registers. - Add support for virtualized ARM Generic Interrupt Controller (GIC) devices and provide an efficient mechanism to manage interrupt delivery to a virtual machine. Providing a GIC device reduces the custom code you need to write to emulate an interrupt controller. - Add support for GIC hypervisor control system registers that GIC devices provide for nested virtualization support. Support for these registers allows hypervisors running in a virtual machine to inject interrupts to their guests. --- Copyright © 2026 Apple Inc.
