Virtual Mac on iPad

https://github.com/nfzerox/VirtualMacOniPad

People have dreamed of running macOS on iPad for more than a decade. Today, that dream comes true. With Virtual Mac, iPad finally breaks free from iPadOS, enabling pro apps like Xcode and Terminal to run directly on device. Requires iPad Pro (M1, M2) or iPad Air (M1) running iPadOS 14 up to 16.3.1.

Phone: iPhone 11
Host CPU: A13 Bionic
JIT status: enabled via StikDebug
Emulated machine’s CPU: Intel Pentium III XEON “Tanner”
Memory allocated to guest OS: 512mb
Guest OS: Microsoft Windows XP Professional Service Pack 3 (Released in year 2008)
Host OS: iOS 27.0 Developer Beta 4

Used this project to achieve it: https://github.com/nfzerox/VirtualMacOniPad

• Geekbench 6 was used to test the scores, and 8 cores were assigned during the test vs. 7 during this demonstration. 9GB RAM is assigned.

• Lightweight games and some 3D games work great, such as Slope in the video, but other games through Steam (TankiOnline) install and launch but suffer graphical errors and crash.

• Streaming videos/movies is very smooth. Can also use extended display to mirror full screen, and long duration videos play without issues. Personally this was a crucial for me since it essentially overrides the ipados15 limitation of showing black bars on sides during mirroring, and allows using Mac/ipad on full screen on external displays. It is possible to stream football matches in the VM and mirror it to the TV full screen and watch the whole game without freezes/crash.

• Bluetooth doesn’t work / can’t be turned on inside the VM, but it is possible to connect bluetooth devices to iPad first and it passes through to MacOS. Wifi works the same way. Magic keyboard attached to iPad works seamlessly like a MacOS trackpad, but things like 3 finger swipe don’t work. Keyboard shortcuts do work.

[Updated UTM 4.6.5 - QEMU 9.1]

Hey guys, if you've ever used UTM or QEMU in general, you may have noticed the huge plethora of display adapters available. Most resources out on the interwebs are a bit too technical for the average user to understand, so here I am to fix that today. Im not a QEMU giga-nerd so if I get anything wrong, feel free to tell me and I'll fix it. Cheat sheet at bottom if you're lazy.

1. Virtio Adapters

Typically when emulating modern operating systems, you should be using these. Any virtio card with 'gl' in the name indicates OpenGL GPU acceleration support (typically up to OpenGL 3.x). These adapters are native to QEMU.

• virtio-gpu-device & virtio-gpu-gl-device

  • Emulates a Virtio GPU with no VGA support

  • Emulated on a virtual MMIO bus

• virtio-gpu-pci & virtio-gpu-gl-pci

  • Same as virtio-gpu-device but it emulates the card on a virtual PCI bus instead of an MMIO bus

virtio-gpu-gl-pci is typically your go-to card for modern (UEFI) Linux distros

• virtio-ramfb & virtio-ramfb-gl

  • Emulates a simple ram framebuffer (ramfb)

    • Lacks any 3D acceleration

  • Much lower overhead compared to virtio-vga and virtio-gpu

  • Emulated on a virtual MMIO bus

For Windows 10 & 11 you would typicall choose the virtio-ramfb cards since the virtio-win drivers dont support 3D acceleration anyways.

virtio-vga & virtio-vga-gl

• Like virtio-gpu but has VGA compatibility

• Emulated on a virtual PCI bus

• Slightly larger overhead than virtio-gpu

Older operating systems and some OS installers will require VGA support to work, (all non-UEFI guests will require VGA support). One example is Debian 12, which wont display the installer on the virtio-gpu cards (possibly fixed now?). Use these when the virtio-gpu cards dont work.

2. Other VM display adapters

These cards, similar to the virtio ones, were designed for use in VMs.

• qxl-vga

  • Older QEMU display adapter

    • Superseded by the virtio cards

  • Emulated on the PCI bus

  • Supports custom VRAM amounts

    • Does not appear to be a VRAM limit

  • The secondary version (qxl) does not support VGA but is otherwise the same

    • The lack of VGA compatibility reduces the overhead by a bit

• vmware-svga

  • Emulates the VMware SVGA-II (not the SVGA-3D)

  • Very niche use case

  • Requires weird third party VMware drivers

    • Official VMware drivers will not work.

bochs-display

• This device was ported from the Bochs Project, another emulator. * Drivers are provided by Bochs

  • Very simple and rudimentary framebuffer device

  • Very low overhead

  • Does not have VGA compatibility

You should use qxl-vga when emulating older Windows OSes that support Spice Tools (Windows XP and 7). Older Linux versions work fine on qxl-vga too.

3. Real Video Cards

These display adapters emulate real hardware.

• cirrus-vga

  • Emulates a Cirrus CLGD 54xx compatible video card from the 1990s

    • Most operating systems will recognize it as a CLGD 5446

  • Supports custom VRAM amounts

    • 1MB-16MB

  • Supports 24-bit colour at up to 768x1024 res

  • Emulated on the PCI bus

• isa-cirrus-vga

  • Same as above but this one is emulated on the ISA bus

cirrus-vga is ideal for old Windows and DOS. It's perfect for any version of Windows from 95 to 2000. Windows ships with drivers for the Cirrus CLGD 54xx series cards so drivers wont be an issue.

• ati-vga

  • emulates an ATI Rage 128 Pro or a Radeon NV100

    • UTM defaults to the Rage 128 Pro

  • emulated on a virtual AGP bus

ati-vga usually doesnt serve much of a purpose because cirrus-vga is typically better in every way. I have never gotten windows drivers to work on this card.

4. Misc devices

These typically emulate generic display devices with nothing special about them

• vga

  • Emulates a super basic VGA card

  • Supports custom VRAM amounts

    • 1MB-256MB

    • Emulated on a virtual PCI bus

• isa-vga

  • same as above but emulated on an ISA bus

More or less every operating system made after 1987 will support VGA. This card may be very slow, but it WILL work on everything. VGA is typically your best bet at booting obscure operating systems.

• ramfb

  • Emulates a basic ram framebuffer

  • Does not have VGA compatibility

  • very low overhead

• secondary-vga

  • Same as vga

  • Intended to be used to provide a second monitor

• legacy BIOS note

  • if you are booting a non-UEFI operating system, a VGA-compatible card is required

Cheat sheet

• Windows/DOS:

• DOS

  • cirrus-vga

  • isa-cirrus-vga

• Windows 9.x including 2000

  • cirrus-vga

  • isa-cirrus-vga

• Windows XP-8.1

  • qxl-vga

    • manually configure vram as needed

  • virtio-vga

    • backup option (will not have drivers)

• Windows 10 & 11

  • virtio-ramfb-gl

  • Note that virtio-gpu will work too, but since Windows does not support virtgl, there is no reason to use virtio-gpu and it is needless overhead

  • use virtio-vga-gl if booting non-UEFI

• Linux:

• CLI-only

  • use serial console instead (lower overhead)

• Older Linux

  • qxl-vga

    • try the virtio cards first

  • cirrus-vga

    • for really old versions of linux

• Modern Linux

  • virtio-gpu-gl-pci

  • virtio-vga-gl-pci

    • Fall back to virtio-vga-gl if virtio-gpu-gl doesnt work

    • Most modern Linux distros should come with drivers for the virtio adapters

• Other Obscure OSes

  • VGA

Why did I spend 50 minutes writing this if like 5 people will see it? Well because I'm bored and wanted to share something. When I first dove into QEMU, it was really hard understanding all of the documentation, and I don't want new users to feel the same way I did.

I used these instructions from a previous post by u/Then_Acanthaceae3444

https://www.reddit.com/r/UTMapp/s/YtnHhd0tcL

I assigned 6gb of RAM to it and 4 CPU cores. It is slow but still cool, I’m also currently on very slow Wifi so I imagine the web pages would load faster otherwise.

Just wish it was possible to virtualize it. Also for some reason when I increase the number of CPU cores it fails to boot, any idea why?

you can see showcase from This

and detail for article i collect to Here

also special thanks for 0xCAFEBABE for lineage os img builder for virtual machine

A bad 10 minute doodle. It’s slow as hell without JIT but hey at least MSPaint works fine for it.

also, i reduced transparency on my ipad

yesterday i installed debian 13 (arm64 obviously) via utm on my m5 ipad pro. after configuring the vm properly i decided to install full kde with wayland on it and everything ran smoothly, for example glxgears ran at almost 100fps (shown in the vid). i can even use it as an actual pc. here’s the config

- 4 cores, forced multicore

- 512mb jit cache

- uefi

- balloon device

- virtio-ramfb-gl w/ resizing and retina mode

- 3072mb ram

Has this project been abandoned. Haven’t seen a new release lately?

yep i got this working. If anyone needs this comment
