How to Clone Mac Hard Drive

Are you looking to clone your Mac hard drive? Cloning your hard drive can be a useful way to back up your data or transfer everything to a new drive.

In this tutorial, we will guide you through the process of cloning a Mac hard drive step by step. Let’s dive in!

What You Will Need:

  • A new hard drive with enough storage capacity to hold your data.
  • A USB or Thunderbolt cable to connect the new drive to your Mac.
  • A cloning software like Carbon Copy Cloner or SuperDuper!

Step 1: Connect the New Drive

Before starting the cloning process, make sure both your Mac and the new drive are powered off. Connect the new drive to your Mac using the USB or Thunderbolt cable. Once connected, power on both devices.

Step 2: Open Disk Utility

Open Disk Utility on your Mac by navigating to Applications > Utilities > Disk Utility. This utility allows you to manage and format your drives.

Step 3: Select Your Current Drive

In Disk Utility, locate and select your current hard drive from the list on the left-hand side of the window. Be careful not to select any other drives as this process will erase all data on the selected drive.

Step 4: Choose “Restore”

Click on the “Restore” tab at the top of the Disk Utility window. This option allows you to copy one disk onto another.

Step 5: Select Source and Destination

In the “Restore” tab, you will see two fields: “Source” and “Destination”. Drag and drop your current drive from the left-hand side into the “Source” field.

Next, drag and drop the new drive you connected earlier into the “Destination” field.

Step 6: Start the Cloning Process

Double-check that you have selected the correct drives for both source and destination. Once you are certain, click on the “Restore” button to start the cloning process.

Disk Utility will begin copying all data from your current drive to the new drive.

Step 7: Wait for Cloning to Complete

The cloning process may take some time depending on the size of your drive and amount of data being transferred. Grab a cup of coffee or engage in other activities while Disk Utility works its magic.

You can monitor the progress bar to estimate how much time is remaining.

Step 8: Verify Cloned Drive

Once Disk Utility completes cloning, it’s important to verify that everything was copied successfully. Disconnect your new drive from your Mac and power off both devices.

Reconnect the new drive and power on your Mac while holding down the Option key. This will bring up a list of available startup disks.

Option A: Boot from Cloned Drive (Recommended)

If you plan to use the cloned drive as your primary startup disk, select it from the list and proceed with booting up your Mac. Ensure that all your files, applications, and settings are intact on the cloned drive before proceeding further.

Option B: Verify Data on Cloned Drive (Optional)

If you only want to verify that the cloned drive contains all your data, select your original drive from the list and boot up your Mac. Connect the cloned drive to your Mac and open Finder.

Browse through the cloned drive’s contents to ensure that everything is present.


Congratulations! You have successfully cloned your Mac hard drive.

Whether you needed a backup or wanted to transfer everything to a new drive, this tutorial has guided you through the process step by step. Remember to keep your original drive intact until you are certain that the cloning process was successful.

Now that you have a cloned copy of your hard drive, you can rest easy knowing that your data is safely backed up or transferred to a new device.

Happy cloning!
