When you are running out of Mac storage, you might consider deleting some pre-installed apps from the system, say, Mail. Deleting the Mail app from your Mac seems like a straightforward task, but it's a bit more complex than you might expect. Since Mail is a built-in app that comes integrated with the macOS, it’s just not designed to be deleted randomly. So, how to delete the Mail app on Mac?

[Complete Guide] How to Delete Mail App on Mac

Can You Delete the Mail App from Mac?

Theoretically speaking, yes, you can delete the Mail app on a Mac, but it’s risky and takes great effort. macOS has built-in protections for system apps to prevent accidental deletion, as these apps are integral to the operating system's functionality. That’s to say, Mail is protected, and you have to disable the System Integrity Protection (SIP) to uninstall it from Mac.

However, this approach is super complex and generally not advisable. Why? Turning off SIP poses an increased vulnerability to malware and viruses in your system. Also, once you regret deleting Mail on Mac, you’ll have to factory reset your macOS system to reinstall it.

With all being said, if you are still determined to delete the Mail app on Mac, read on to know how.

How to Uninstall the Mail App on Mac [4-Step Guide]

Removing the Mail app from a Mac involves a series of steps, starting with the temporary disabling of SIP via macOS Recovery. Below is a comprehensive guide to safely disable SIP, remove the Mail application via Terminal, get rid of Mail leftovers, and then re-enable SIP to ensure your Mac's security is restored.

Step 1: Disable System Integrity Protection

Based on the chip of your current Mac device, whether it’s Intel or Apple Silicon chip, the steps to enter macOS Recovery mode can vary.

  • For Intel-based Macs:

    1. Turn off your Mac.
    2. Press the power button, then immediately hold down Command-R until the Apple logo appears.
    3. Release Command-R once the macOS Utilities window is displayed.
  • For Macs with Apple Silicon Chips:

    1. Shut down your Mac.
    2. Press and hold the power button until the startup options window appears.
    3. Select "Options", then click "Continue".
    4. When prompted, enter your admin password and click "Continue".

Once you are in the recovery mode, you can disable SIP by the following:

  1. Navigate to Launchpad > Other > Terminal and run it.
  2. Enter the command below and press Return: csrutil disable

  3. Restart your Mac.

Step 2: Remove the Mail App

With SIP now disabled, you have the chance to permanently delete the Mail app using Terminal commands.

  1. Navigate to Applications > Utilities and launch Terminal.
  2. Navigate to the System Applications Directory by entering the command: /System/Applications/ and hit Return.
  3. Execute the command to delete Mail from your system: sudo rm -rf
  4. Confirm the action by typing your password when prompted.

It’s not over yet. After permanently uninstalling the Mail app from Mac, you can keep on hunting its leftovers down and delete them manually for a more optimized Mac storage. Here’s how to get rid of Mail files and folders via Finder:

  1. Right-click the Finder icon in the Dock. From the drop-down menu, choose the "Go to Folder" option.

  2. Search each directory below, as they are all mail-related folders and files:

    • ~/Library/Containers/
    • ~/Library/Mail/
    • ~/Library/Preferences/
    • ~/Library/Application Scripts/

  1. Use the search box in Finder, and type in to precisely locate these files. Once selected, drag any related files/folders to the Trash.

Step 4: Re-enable System Integrity Protection (SIP)

After successfully removing the Mail app and its related data, it's crucial to re-enable SIP to protect your system's integrity.

  1. Follow the previous steps to enter Recovery Mode for either Intel-based or Apple Silicon Macs.
  2. Once in Recovery Mode, open Terminal from the Utilities menu as well.
  3. Type the command csrutil enable and press Return.
  4. Restart your Mac to complete the process.

By carefully following these steps, you can remove the Mail application from your Mac for real. However, as this method is both risky and complicated, we have a better way to deal with the Mail app on Mac, that is to disable and hide it. By doing so, the Mail app only takes up about 50 MB of space.
