If you’ve ever explored the operating system of your Mac, you’ve most likely seen the term, “Mac OS Base System.” It’s understandable that you probably had no idea what that meant.
To save you some research time, let me explain what this Base System is and why you should never erase it.
What Is the Mac Os Base System?
When you enter Recovery mode via Disk Utility, you’re likely to find a volume called macOS Base System or Mac OS X Base System.
The Mac OS base system is the recovery partition on Macs. It consists of a minimum macOS installation that has the bare essentials necessary to run macOS.
What’s Included in The Mac Os X Base System?
A few key components of the Mac OS X base system include the Finder, Dock, and System Preferences.
- Finder helps you find the contents of your Mac using a series of icons and windows. With Finder, you can do everything from finding an important file to changing your wallpaper.
- The dock is essential for displaying your most used Apps. The Dock lets you quickly open an app with a single click or keyboard shortcut.
- System Preferences is where you’ll find tools to fine-tune your Mac experience. This includes desktop appearance, screensaver, network connections, and more.
Those are the main parts of the Mac OS Base System. This system also includes a variety of other programs, including Safari (the web browser), Mail (the email software), Notes (a note-taking program), and Calendar (an event organizer).
When to Use the Mac Base System?
There are a few reasons you might need to use the base Mac system:

The Disk Locked Error and the macOS Base System
The Disk Locked error is a typical problem that users encounter when attempting to utilize the macOS Base System. It occurs when the Base System, which should only contain a Disk Image of around 2GB, mirrors the hard drive size and displays an error.
This usually happens when you accidentally restore your Macintosh HD to the base system. You’ll need to reset the base system in Recovery Mode to solve this issue.
Should You Erase the Base System?
No, it’s not a good idea to erase the Mac OS Base System. The Base System does not take up enough space to provide a space-saving benefit.
Also, if you erase the Base System, you will face macOS restore issues down the line that you may not be able to fix.
How Do I Install the Mac Os X Base System?
In the world of computers, mistakes happen, and problems pop up. If something happens and your Base System is erased, here’s how to reinstall it.
You can install the Mac OS X base system from a recovery partition or a USB drive.
If your PC has a recovery partition, you can install the Mac OS X base system by restarting it and holding down the Command and R keys until the Apple logo appears. Then select Reinstall macOS from the menu, and follow the onscreen instructions.
You can also reinstall the Mac OS X base system with a USB drive. You will need a USB drive with 12GB of storage space and the macOS installer app.
