Why can’t I delete Mail from my Mac?

Some users may not need the Mail app. For example, they might use third-party tools for managing emails on their Mac. However, if you have ever tried to uninstall Mail from Mac, you might have seen the message on macOS: “Mail app can’t be modified or deleted because it’s required by macOS.”

Why do you see this message?
The reason you can’t uninstall Mail is because Apple’s System Integrity Protection (SIP) restricts the ability to modify pre-installed applications on Macs. Apple intentionally implemented this restriction to prevent less-experienced users from accidentally removing important files and compromising the system’s stability. It’s a protective measure.

On the old version of macOS, you could disable SIP and uninstall Mail using Terminal. However, today, even if you uninstall Mail (or any other default application) on Mac, the system will automatically restore the deleted application.
