Are you running out of disk space on your Mac? Or do you want to upgrade the macOS disk to a larger SSD? To achieve this without data loss, the best way is to clone the macOS disk to a new SSD.

Fortunately, cloning your MacOS to a new SSD is relatively easy. In this guide, EaseUS will show you the right tool and the required steps to transfer everything from your old drive to the new one. It'll also make your Mac run faster than ever before.

How to Clone macOS to New SSD? - 4 Stages

Now, while following the steps that I mentioned below, there are certain things you'll need:

First, a new SSD is a solid-state drive where you'll store the Data from your Mac's drive. We'll connect the SSD to the Mac; hence, prepare an Adapter or Enclosure if your Mac doesn't have the USB Port or the one that your SSD needs. Further, we'll use a tool or built-in software for risk-free cloning, EaseUS Partition Master for Mac.

Lastly, for formatting, we'll erase the SSD Data. Hence, drive and back up everything before taking the first step.

Stage 1. Connect the New SSD to the Mac

You have taken the time to consider it, and now it's time to link the SSD with your device.

Step 1: Take the new SSD and cable to do this. Connect the SSD with a cable, and plug its other end into your Mac's USB port. You'll get a free port on the side of your MacBook. Use an adapter or USB hub if you can't connect the SSD because the USB port is absent.

Step 2: A USB or similar icon on the Mac screen. This will show if everything you have done is perfect and the SSD is formatted. If this is not the case, the next step will reveal what to do.

Step 3: If you didn't find the drive icon or the Mac didn't detect the SSD, open the Disk Utility App by heading to the menu or using Finder. Select the new drive (SSD) from the App's left menu.

Step 4: Select the Erase button from the top menu, choose a compatible format (ExFAT) from the list, and click the Erase option.

Stage 2. Install the Cloning Software

A lot of software is used when cloning macOS, but the one I found works the best is EaseUS Partition Master for Mac. Why? It's compatible with macOS 10.15 (Catalina), macOS 11 (Big Sur), macOS 12 (Monterey), macOS 13 (Ventura), macOS 14 (Sonoma), and macOS 15 (Sequoia), so your Mac will easily read it.

Additionally, it supports HFS, HFS+, APFS, FAT, exFAT, and NTFS file systems and Supported Architectures: Intel-based Macs, M1 Macs, M2 Macs, and M3 Macs that your MacBook is compatible with.

So here are the steps to install the software on Mac:

Step 1: Open a browser, for instance, Safari, and search EaseUS Partition Master. Or visit https://www.easeus.com/.

Step 2: Navigate to the header and hover over Partition Manager. A drop-down menu will open. Select Partition Master for Mac and wait until it downloads.

Step 3: Open the Finder and head to the download directory after downloading. You'll find a file that has just been downloaded that ends with .dmg, a file extension for MacOS to install a program.

Step 4: Once you get the file, double-click on it, and a prompt will show on the dashboard. As the prompt shows, drag the EaseUs software icon to the right side.

Step 5: A new icon will appear on the home screen after installation. It would be best to click on it and select Eject.

After doing so, go to the App section and open the EaseUs software.

Stage 3. Clone macOS to New SSD

If you want to keep and copy existing data to a new drive, close the macOS to a new SSD. Once you do that, you can always boot from that. Here is how to clone macOS to the new SSD using EaseUS Partition Master for Mac.

Step 1. Install and connect another new disk to Mac computer, run EaseUS Partition Master for Mac, then, click "Clone" under the Abilities section. Click the "+" icon to browse and locate the macOS disk and target new disk.

Step 2. Select the Source and the Destination disk and click "Select" to confirm.

Step 3. Confirm if you've selected the correct macOS OS disk and the new target disk you'd like to clone and upgrade the macOS disk to. Then, click "Start" and click "Yes" to confirm if EaseUS Partition Master for Mac requests you to confirm the operation.

Step 4. Wait patiently and let EaseUS Partition Master for Mac to complete cloning the old macOS disk to the new target disk.

Stage 4. Replace the Old Disk

After you clone the MacOS to the SSD, you can remove the traditional Hard disk with this SSD. You'll get all the files and data in the Macbook.

Here are the steps to replace the disk:

Step 1: Turn the Macbook upside down and take a screwdriver suitable to remove the screws from the base. Take the base out of the Macbook.

Step 2: You can see the hard drive. Unplug the battery connector using a physical tool, such as a screwdriver.

Step 3: Loosen the four screws on the hard drive and lift the plastic tab slowly and carefully. It's still connected to a drive cable, so remove it. After that, you can remove the hard drive altogether.

Step 4: Take the SSD. Connect it to the driver cable that we have unplugged before. Add the four screws, and don't forget to reconnect the battery connector. Join the base of your MacBook.

Step 5: Now, turn on the Mac in the internet recovery mode. For this, press the power button and then the Command + Option + R buttons. Once a globe appears on the screen, release the keys and further install the MacOS.
