How to Uninstall Windows on Mac: A Step-by-Step Guide

posted on March 17, 2026

Uninstalling Windows on a Mac might sound tricky, but it’s actually quite straightforward. You’ll be using the Boot Camp Assistant to remove Windows and reclaim the space on your Mac. Just follow a few steps to safely uninstall Windows and get your Mac back to its original state.

How to Uninstall Windows on a Mac

In this section, you’ll learn how to use Boot Camp Assistant to uninstall Windows from your Mac. By the end, you’ll have removed Windows completely, freeing up storage space and simplifying your system.

Step 1: Backup Your Data

Before you start, make sure to back up any important files from the Windows partition.

Backing up ensures that you don’t lose any important data during the uninstallation. Use an external drive or cloud storage to save your files.

Step 2: Open Boot Camp Assistant

Go to Applications > Utilities, and open Boot Camp Assistant.

Boot Camp Assistant is the tool you’ll use to remove Windows. It’s specifically designed for handling dual-boot setups on Macs.

Step 3: Remove Windows Partition

In Boot Camp Assistant, select "Remove Windows 7 or later version."

This option will guide you through removing the Windows partition, effectively uninstalling Windows from your Mac.

Step 4: Confirm Removal

Follow the on-screen instructions to confirm the removal of the Windows partition.

Confirming the removal will delete Windows and merge the space back into your Mac’s main drive.

Step 5: Restart Your Mac

Restart your Mac to finalize the changes.

A restart ensures everything is properly configured, and your Mac should now be back to its original macOS-only setup.

Once you’ve completed these steps, Windows is no longer on your Mac. Your Mac will revert to a single-partition drive, solely running macOS.
