Step 3.
Now, go to the Utilities folder and double-click the Terminal app to run it.

Fire up the Terminal app in the Utilities folder.
Step 2.
Type the command csrutil enable into the Terminal app and press the Return key on your keyboard.

Part 3: FAQs about Deleting Mail App on Mac

Question 1. Does Mail take up space on Mac?

Yes, the Mail app does not let you receive and send emails but also downloads the messages and attachments to your hard disk. The amount of storage it takes up is determined by the type and number of your emails. If you have subscribed to a bunch of brands and newsletters, it comes considerably large and may slow down your computer.

Question 2. How to prevent Mail from downloading messages?

Go to the Mail menu, choose Preferences, and then Accounts. Click an account, and choose the Mailbox Behaviors. Click on the menu beneath Erase junk messages, and select a period. Click the menu under Erase deleted messages, and select a period too. Then the Mail app will delete messages regularly. You can stop Mail from downloading attachments in the Account Information tab on the Accounts dialog.

Question 3. Why I cannot delete Safari plugins?

Once you delete the Mail app on Mac, you cannot receive or send emails anymore. That may bring trouble to your machine. Therefore, you'd better use a third-party email client or reinstall the Mail app to your machine.
