Installing XQuartz and Creating a Bootable macOS USB Disk

If you're running macOS High Sierra (10.13.6) or earlier, you may need to install XQuartz to access certain features and applications that require an X11 environment. In this article, we'll explore how to do just that.

What is XQuartz?

XQuartz is an open-source effort to develop a version of the X. Org X Window System that runs on macOS. It's an essential tool for developers who need to use Linux-based applications and tools on their Macs.

Installing XQuartz

To install XQuartz, simply visit the official website and download the DMG installer. Once downloaded, open your Mac's "Applications" folder and look for the "Install XQuartz" app. Run the installer and follow the prompts to complete the installation process.

Important Notes

After installing a system software update from Apple, you may experience conflicts with XQuartz due to the X11 package clobbering Apple's X11.app. To resolve this issue, please re-install the latest XQuartz X11 release for Leopard after installing a system software update to OS X 10.5.x Leopard.

Creating a Bootable macOS USB Disk

If you want to install macOS on multiple devices or create a bootable USB disk, you can use the full-size macOS installer from Apple's website. To do this, follow these steps:

1. Visit Apple's website and download the "Install macOS Monterey *" app.
2. Open your Mac's "Applications" folder as shown below.
3. Locate the "Install macOS Monterey *" app and copy it to a safe location.

To create a bootable USB disk, you'll need to use Terminal command. The steps are as follows:

1. Visit Apple's website for the Terminal command needed for making a USB drive from the downloaded "install macOS" app.
2. Copy-paste the required command for your OS version into the Terminal app in your Mac.

For example, if you're using macOS Monterey 12.6, you can use the following command:
```
sudo /Applications/Install\\ macOS\\ Monterey.app/Contents/Resources/createinstallmedia --volume /Volumes/USB
```
Replace "/Volumes/USB" with the path to your USB drive.

By following these steps, you should be able to install XQuartz and create a bootable macOS USB disk.
