By default, when you purchase a new Mac, the primary internal storage drive is simply named “Macintosh HD”. This has been the standard naming convention for Apple computers for decades. However, if you are managing multiple Macs on a local network, syncing data across devices, or just want to personalize your computer, you might want to give your hard drive a more descriptive name.
Renaming your primary hard drive (or any externally connected USB drive or SSD) on macOS is an incredibly simple process that does not require reformatting the drive or losing any data.
How to Rename the Drive on Your Desktop
If your Mac is configured to show hard drives directly on your desktop, renaming it is as easy as renaming a folder.
- Locate the Macintosh HD icon on your desktop (typically found in the top-right corner).
- Click the icon once to highlight it.
- Press the Return (Enter) key on your keyboard. The text below the icon will become highlighted in blue.
- Type your new desired name (e.g., “Work SSD” or “Dave’s Mac”).
- Press the Return key again to save the change.
Because you are renaming the primary system volume, macOS will prompt you for authentication. You will need to enter your Mac’s administrator password (or use Touch ID) to confirm the change.
How to Rename the Drive in Finder
If you prefer a clean desktop and have hidden your hard drive icons, you can easily rename the drive from a standard Finder window.
- Open a new Finder window (click the smiling face icon in your Dock).
- In the left-hand sidebar, look under the Locations section. You should see “Macintosh HD” (or your current drive name) listed there.
- Right-click (or Control-click) on the drive name in the sidebar.
- Select Rename from the context menu.
- Type the new name for your drive and press Return.
- Enter your administrator password when prompted to authorize the change.
Important Considerations Before Renaming
While renaming your hard drive is perfectly safe for standard daily use, there are a few edge cases to consider:
- Automated Scripts: If you have written custom Bash or Zsh scripts in the Terminal that rely on absolute file paths containing
/Volumes/Macintosh HD/, those scripts will break and need to be updated with the new name. - Legacy Software: Some older, poorly coded third-party applications might hardcode “Macintosh HD” into their directory paths. If an older app suddenly stops working after the rename, you may need to reinstall it or change the drive name back.
Modern macOS software and built-in Apple applications use relative paths and UUIDs (Universally Unique Identifiers), so they will continue to function perfectly regardless of what you name the drive.
