How to Download and Install macOS Lion DMG

If you're looking to download and install macOS Lion DMG, you've come to the right place. In this article, we'll walk you through the process of downloading and installing macOS Lion DMG.

Note 2: Running Cmd+Shift+G in Finder will allow you to easily jump to ~/macOS-Installer and set up the installer to finish your work.

First things first, move the Install macOS.app into the /Applications folder as we'll be executing commands from there. Once finished, you'll find a DMG containing the macOS Installer, called Install_macOS_11.1-20C69.dmg for example.

Mount it and you'll find the installer application. This is going to take a while as we're downloading the entire 8GB+ macOS installer, so it's highly recommended to read the rest of this guide while you wait.

If you need a particular version of macOS, you can select it by typing the number next to it.

Getting Started with Downloading and Installing macOS Lion DMG

To start, we'll want to grab ourselves a copy of macOS. While you don't need a fresh install of macOS to use OpenCore, some users prefer having a fresh slate with their boot manager upgrades.

Once you have your copy of macOS, you can skip this step and head to formatting the USB if you're just making a bootable OpenCore stick and not an installer.

Using Mkdir and Curl Commands

To get started, open a terminal window and copy and paste the below command:

mkdir -p ~/macOS-installer && cd ~/macOS-installer && curl > installinstallmacos.py && sudo python installinstallmacos.py

This will give you a nice list of macOS installers.

Troubleshooting Common Issues

If you've already mapped your USB ports and disabled XhciPortLimit, you can boot macOS 11.3+ without issues.

However, if you're experiencing issues with XhciPortLimit, be aware that it's broken in macOS 11.3 and newer, resulting in boot loops.

In this article, we've walked you through the process of downloading and installing macOS Lion DMG. With these simple steps, you'll have your copy of macOS installed on a USB drive in no time.

Remember to always map your USB ports before installing macOS 12 and above, as recent macOS versions introduce changes to the USB stack.
