Apple Silicon Mac Virtual Machines
Everything you need to know about running macOS virtual machines on M1, M2, M3, and M4 Macs. Native ARM performance, no emulation required.
A New Era for Mac Virtualization
When Apple transitioned from Intel to Apple Silicon in 2020, everything about Mac virtualization changed. The old approaches — VMware Fusion, Parallels running x86 Windows, VirtualBox — either stopped working or required fundamental redesigns.
But Apple also introduced something new: Virtualization.framework, a native API for running virtual machines on Apple Silicon. This wasn't just a port of Intel virtualization — it was built from the ground up for ARM.
Why most Intel VM guides are obsolete
If you're searching for Mac VM tutorials and finding old content about VMware or VirtualBox on Intel Macs, that information doesn't apply to Apple Silicon. The architecture, tools, and constraints are completely different.
How Apple Silicon VMs Work
Virtualization.framework
Apple's Virtualization.framework is a first-party hypervisor API introduced in macOS 11 Big Sur. It provides:
- Hardware-accelerated virtualization — uses the CPU's virtualization extensions directly
- Paravirtualized devices — efficient virtual network, storage, and display
- macOS guest support — run macOS inside macOS (starting with macOS 12)
- Linux guest support — run ARM64 Linux distributions
ARM64 Architecture
Apple Silicon Macs use ARM64 (AArch64) processors. This means:
- Guest VMs must be ARM64 — you can't run x86 Windows or Linux
- No Intel emulation — unlike Rosetta 2 for apps, there's no x86 emulation for VMs
- Native macOS performance — ARM macOS guests run at near bare-metal speed
IPSW Restore Images
Unlike Intel Macs where you could boot from a macOS installer, Apple Silicon VMs use IPSW restore images — the same format used for iOS and Apple Silicon Mac recovery. You download an IPSW file and "restore" it to create a new VM.
What Works (and What Doesn't)
What Works Great
| Feature | Details |
|---|---|
| macOS guests | Full support. Run macOS 12 Monterey through macOS 15 Sequoia. |
| Xcode | Works perfectly, including iOS Simulator. |
| Development tools | Homebrew, Node.js, Python, Ruby, Go, Rust — all native ARM. |
| Docker | Docker Desktop works. Runs ARM64 Linux containers. |
| GUI apps | Full GPU acceleration. Smooth graphics and animations. |
| Networking | NAT networking out of the box. Internet access works. |
| Shared folders | VirtioFS for high-performance file sharing. |
| ARM64 Linux | Ubuntu, Debian, Fedora ARM editions work well. |
What Doesn't Work
| Feature | Why |
|---|---|
| x86 Windows | Requires x86 emulation. Use Windows 11 ARM instead (Parallels). |
| x86 Linux | No x86 emulation. Use ARM64 Linux distributions. |
| Nested virtualization | Can't run VMs inside VMs (hardware limitation). |
| USB passthrough | Not supported in Virtualization.framework. |
| iCloud / Apple ID in guest | Works but may cause issues. Best to use separate Apple ID. |
| FileVault in guest | Technically works but not recommended. |
The "Works, With Caveats" List
- Windows 11 ARM — runs via Parallels Desktop (commercial). Can use x86 emulation inside Windows for some apps.
- Android emulator — ARM Android emulator works in Android Studio, but performance varies.
- Multiple displays — supported but depends on the VM software.
Performance Guide
CPU Performance
macOS VMs on Apple Silicon run at near-native speed. The hypervisor overhead is minimal — typically less than 5% for CPU-bound workloads. This is because:
- No instruction translation (unlike x86 emulation)
- Hardware virtualization extensions in Apple Silicon
- Efficient paravirtualized devices
Memory Considerations
Apple Silicon Macs have unified memory (shared between CPU and GPU). When allocating memory to a VM:
- 8GB Mac — 4GB for VM is comfortable for light work
- 16GB Mac — 8GB for VM allows serious development
- 32GB+ Mac — 16GB for VM enables Xcode + Simulator
Memory pressure
If your Mac starts swapping heavily, reduce VM memory allocation. It's better to have a VM with less RAM than to have both host and guest fighting for memory.
Storage Performance
Apple Silicon Macs have fast NVMe storage. VMs benefit from:
- Sparse disk images — only consume actual used space
- APFS cloning — instant copy-on-write duplicates
- VirtioFS shared folders — near-native file access speed
M1 vs M2 vs M3 vs M4 for VMs
All Apple Silicon chips support Virtualization.framework equally. The differences are in raw performance:
| Chip | VM Recommendation |
|---|---|
| M1 / M1 Pro / M1 Max | Great for VMs. The baseline for Apple Silicon virtualization. |
| M2 / M2 Pro / M2 Max | ~15-20% faster than M1. Better memory bandwidth. |
| M3 / M3 Pro / M3 Max | ~20-30% faster than M2. Dynamic caching improves efficiency. |
| M4 / M4 Pro / M4 Max | Latest generation. Best performance and efficiency. |
Bottom line: Any Apple Silicon Mac can run macOS VMs well. If you're buying new and plan to run multiple VMs simultaneously, prioritize RAM over CPU tier.
Getting Started
Requirements
- Mac with Apple Silicon (M1, M2, M3, M4, or later)
- macOS 13 Ventura or later for guest VMs
- At least 8GB RAM (16GB+ recommended)
- 20GB+ free disk space per VM
Create Your First VM
# Download a macOS restore image (IPSW)
# Available from Apple or via the GhostVM Restore Images window
# Create a new VM
vmctl init ~/VMs/my-vm.GhostVM \
--cpus 4 \
--memory 8 \
--disk 64
# Install macOS
vmctl install ~/VMs/my-vm.GhostVM
# Start the VM
vmctl start ~/VMs/my-vm.GhostVMRunning Multiple VMs
Apple Silicon is efficient enough to run multiple VMs simultaneously, but be mindful of memory:
# Clone an existing VM for instant duplication
# Uses APFS copy-on-write — near-zero disk overhead
# In GUI: right-click VM → Clone
# Each clone gets a unique identity (MAC address, machine ID)GhostVM for Apple Silicon
GhostVM is built specifically for Apple Silicon Macs. Native Virtualization.framework integration, instant cloning, snapshots, and a scriptable CLI. Free and open source.
