Last Updated: Mar 7, 2024 by

If you’re a Mac user, you may have noticed that your Messages app can quickly become cluttered with old conversations and messages. While it’s nice to have a record of your conversations, it can also be overwhelming and take up valuable storage space on your computer.

Fortunately, there is a way to delete all messages on your Mac at once. In this article, we’ll walk you through the steps to delete all messages on your Mac and free up some space on your computer.

Why Delete All Messages on Mac?

There are a few reasons why you may want to delete all messages on your Mac.

Free Up Storage Space

One of the main reasons to delete all messages on your Mac is to free up storage space. Messages can take up a significant amount of space on your computer, especially if you have a lot of attachments or media in your conversations. By deleting all messages, you can free up space for other important files and documents.

Improve Performance

Having a large number of messages on your Mac can also slow down your computer’s performance. This is especially true if you have a lot of media and attachments in your conversations. By deleting all messages, you can improve the overall performance of your Mac.

Protect Your Privacy

If you share your Mac with others, you may not want them to have access to your old messages. By deleting all messages, you can protect your privacy and ensure that your conversations remain private.

How to Delete All Messages on Mac

Now that you know why you may want to delete all messages on your Mac, let’s dive into the steps to do so.

Step 1: Open the Messages App

The first step is to open the Messages app on your Mac. You can do this by clicking on the Messages icon in your dock or by searching for “Messages” in Spotlight.

Step 2: Select All Conversations

Once the Messages app is open, click on the “Messages” tab in the menu bar and select “Preferences” from the drop-down menu. In the Preferences window, click on the “General” tab and then click on the “Select All” button. This will select all of your conversations in the Messages app.

Step 3: Delete Conversations

With all of your conversations selected, click on the “Delete” button in the bottom right corner of the Preferences window. A pop-up window will appear asking if you want to delete all messages. Click on “Delete” to confirm.

Step 4: Empty Trash

After deleting all messages, you will need to empty your trash to permanently remove them from your computer. To do this, click on the “Trash” icon in your dock and then click on “Empty” in the top right corner of the window. This will permanently delete all of your messages from your Mac.

Tips for Deleting Messages on Mac

Here are a few tips to keep in mind when deleting messages on your Mac:

Backup Your Messages

Before deleting all messages, it’s a good idea to backup your conversations in case you need to access them in the future. You can do this by going to File > Export Conversations in the Messages app. This will create a backup file that you can save to your computer or an external hard drive.

Use the Search Function

If you only want to delete specific conversations, you can use the search function in the Messages app to find them. Simply type in a keyword or contact name in the search bar to filter your conversations.

Consider Archiving Conversations

Instead of deleting all messages, you may want to consider archiving conversations that you no longer need. This will remove them from your main Messages window but keep them in an archived folder in case you need to access them in the future.


Deleting all messages on your Mac can help free up storage space, improve performance, and protect your privacy. By following the steps outlined in this article, you can easily delete all messages on your Mac and keep your Messages app clutter-free. Remember to backup your conversations before deleting them and consider archiving conversations instead of deleting them if you think you may need to access them in the future. With these tips, you can keep your Mac running smoothly and efficiently.
