# How to download and build macOS Installers
* [Downloading](#downloading)
* [Building](#building)
This doc is centered around downloading and writting the macOS installer to a USB. If you're already familair with how to do this, you can skip.
* Note: 16GB+ USB will be required for the installer
## Downloading
The simplest way to download macOS installs would be to use installinstallmacos:
```sh
mkdir ~/macOS-installer && cd ~/macOS-installer && curl -O https://raw.githubusercontent.com/munki/macadmin-scripts/main/installinstallmacos.py && sudo python installinstallmacos.py
```

As you can see, we get a nice list of macOS installers. If you need a particular versions of macOS, you can select it by typing the number next to it. For this example we'll choose 10:
![](../images/munki-process.png)
This is going to take a while as we're downloading the entire 12GB+ macOS installer.
Once finished, you'll find in your `~/macOS-Installer/` folder a DMG containing the macOS Installer, called `Install_macOS_11.1-20C69.dmg` for example. Mount it and you'll find the installer application.
* Note: We recommend to move the Install macOS.app into the `/Applications` folder, as we'll be executing commands from there.
* Note 2: Running Cmd+Shift+G in Finder will allow you to easily jump to `~/macOS-installer`

## Building
Now we'll be formatting the USB to prep for both the macOS installer and OpenCore. We'll want to use macOS Extended (HFS+) with a GUID partition map(Using GUID is important for the patcher). This will create two partitions: the main `MyVolume` and a second called `EFI` which is used as a boot partition where your Mac's firmware will check for boot files.
* Note: By default, Disk Utility only shows partitions – press Cmd/Win+2 to show all devices (alternatively you can press the View button)

Next run the `createinstallmedia` command provided by [Apple](https://support.apple.com/en-us/HT201372). Note that the command is made for USB's formatted with the name `MyVolume`:
```sh
sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
```
* Note: You can also replace the `createinstallmedia` path with that of where your installer's located (same idea with the drive name).

## Cannot boot macOS without the USB
At this time, the OpenCore Patcher won't install OpenCore onto the internal drive itself during installs. Instead, you'll need to either [manually transfer](https://dortania.github.io/OpenCore-Post-Install/universal/oc2hdd.html) OpenCore to the internal drive's EFI or run this patcher's Option 2 again but select your internal drive.

Reminder that once this is done, you'll need to select OpenCore in the boot picker again for your hardware to remember this entry and auto boot from then on.
