# Preparing the VM

## What we are going to do:

* [Download the installation ISO](/utm/installing-operating-systems/macos-mac-os/mac-os-x-10.5/preparing-the-vm.md#download-the-install-image)
* [Create and configure the VM](/utm/installing-operating-systems/macos-mac-os/mac-os-x-10.5/preparing-the-vm.md#make-and-configure-the-vm)

## Download the installation ISO

Download an ISO from the internet, or make an ISO from a disk you have.

## Create and configure the VM

1. Open UTM
2. Tap the + icon

### Info

#### Give your machine a name

1. Set a name for the Virtual Machine

#### (Optional) Set an icon

1. Tap "Style"
2. Tap "Operating System"
3. Tap the white computer
4. Tap any of the icon you'd like

### System

#### Setting the architecture

1. Tap "Architecture"
2. Select "PowerPC"
3. Tap "System"
4. Select "Mac99 based PowerMAC (mac99)"

#### Set the amount of RAM

{% hint style="info" %}
The minimum amount is 512 MB.
{% endhint %}

1. Drag the slider to your preferred amount

### Drives

#### Making the hard drive

UTM currently uses the .qcow2 format for its hard drives. There are a lot of pros of this, but Leopard doesn't seem to like the format. When the installation is done, the machine fails to boot. I have found a workaround, but you'll need a computer for it.

1. Install QEMU on your computer
2. Run this command in your terminal:

```
qemu-img create hda.img <size>M
```

You will end up with a file called "hda.img" in the directory you ran the command from.

Transfer this file to your device.

1. Open UTM
2. Tap your VM
3. Go into its config
4. Go to "Drives"
5. Tap the Import button
6. Find the file and tap it
7. Set the type to disk - ide
8. Save your settings

#### Mounting the ISO

1. Tap the Import button
2. Find your ISO file and tap it

{% hint style="info" %}
Your image will probably be in On My iPhone > Downloads, as that is the default downloads folder.
{% endhint %}

### The Sound section

Mac OS X 10.5 crashes if you have sound on. Turn it off:

1. Toggle "Enabled" off

Save your settings.

## That's it!
