Dreading the time-consuming process of setting up a new Mac or worried about losing important files due to accidental damage or theft? Cloning your Mac can be the ultimate solution for ensuring a seamless transition to a new machine or creating a robust backup system.
In this article, we'll show you how to clone Mac hard drive, allowing you to effortlessly replicate everything from your apps to your preferences, saving you time, effort, and the potential loss of invaluable data.
When it comes to the data backup task, most likely, the first thing that comes to your mind is Apple's native backup feature Time Machine. However, is it the best solution? Let's understand the nuances.
The difference between cloning and using Time Machine
Time Machine and disk cloning are two basic ways to back up your Mac files. How do they differ from each other?
Time Machine is Apple's standard method for creating incremental backups. When enabled, it periodically backs up your Mac, keeping the most recent versions in case you need to revert to a backup from a specific point in time.
Disk cloning is significantly different from creating backup copies using Time Machine: this tool allows you to copy not only individual folders and files but even the operating system and all installed programs. That is, cloning is creating an exact copy of your existing disk with the possibility of further use on another device or the same Mac if necessary.
Cloning is great for those who need control, especially for businesses that may need to clone drives with sensitive business data like tax info or client files.
We advocate for pro tools like Disk Drill and recommend you use its Byte-to-Byte Backup feature to quickly create a clone (disk image) of your entire hard drive. This will save you from any disaster as you can recover all your data from the clone if your hard drive fails or gets damaged. Disk Drill is also a powerful data recovery tool, so you can use it to try to recover any files you haven't backed up.
So, what method to choose depends on your needs.
Choose Time Machine Backup when you need to maintain a history of changes to your files and want the ability to recover individual files or the entire system to specific points in time.
Choose disk cloning when you want a complete and exact duplicate of your entire system for migration, backup, and quick recovery scenarios.
Before you start
Before starting cloning your Mac, it's always a good idea to run a regular backup routine. It may seem redundant to create a backup just before creating another backup, but it's better to be safe than sorry. If you plan on using a disk that has been used before, make sure to erase it completely to prepare it for the clone. Assuming you want to use the whole disk as a single volume, you can proceed with the cloning process.
For managing your backups, try Get Backup Pro, which offers various features such as full or incremental backups, folder syncing across multiple Mac computers, and creating bootable clones for new machines or reboots. You can also schedule backups at your convenience and save them to any external drive.
How to prepare your SSD or other external drive to use for your clone
Before we tell you how to clone a Mac hard drive for use as a backup, you need to prepare a place for the clone to live.
- Connect the external drive to the appropriate port on your Mac
- Use Spotlight to locate the Disk Utility app. Press the Command +Space bar and type in Disk Utility
- After you open Disk Utility, locate and select the drive under External. It will usually be named after the company that manufactured it
- Click the Erase tab at the top of the window
- Erase an external hard drive in Disk Utility
- Name the drive and select macOS Extended (Journaled) from the format list
- Click Erase
- Click Done when the process is complete
- Close the Disk Utility window.
Create a clone of your Mac with one click
Finally, let's start the cloning process. If you want to clone your Mac hard drive to an SSD easily, use a Mac hard drive clone software such as Disk Drill.
Here's how to clone Mac hard drive to SSD using the Disk Drill tool:
- Install and open Disk Drill on your Mac
- Connect your external drive to your computer
- Click Backup in the toolbar
- Then choose Backup into DMG Image
- In the popup window, click OK, Let's Do It
- Choose your Mac's boot disk (typically Macintosh HD)
- Click Backup
- When asked where you want to save your backup, select the external drive
- Next, click Save.
Disk Drill will now create an exact copy of your boot drive as a disk image, saved on the external drive, and that's how you clone external hard drive Mac.
How to create a clone of your Mac using Disk Utility
To clone a hard drive on a Mac, you can also use a built-in macOS utility called Disk Utility.
- Open Disk Utility. Use Spotlight search to find and launch the app. Just press the Command + Space bar at the same time and then type in Disk Utility. The app will appear as one of the results
- Once you've launched Disk Utility, select the backup drive you want to clone your Mac hard drive to as the target drive. Next, click Restore
- Disk Utility will display a new window with a drop-down menu labeled Restore from. Select your Mac SSD (usually APPLE SSD XXX) as the source drive from the drop-down menu, then click Restore to begin the cloning process
- Disk Utility will then show you a status bar that slowly fills up as it clones your drive. When it's finished, click Done to complete the process. That's how you clone Mac hard drive with Disk Utility.
Restore the clone
Now you have a Mac hard disk clone on an external drive. If you ever need to restore your Mac from a clone, here's how:
- Turn off your Mac
- Connect the external drive to the appropriate port on your computer
- Then turn on your Mac
- Hold down the Command + R keys as soon as the system restarts to enter macOS Recovery Mode. Your Mac will boot to the macOS Utilities screen
- Click on Disk Utility and then click Continue
- Select your hard drive
- Next, click on the Restore tab at the top of the Disk Utility window
- Select your external drive next to Restore From
- Then select your Mac's hard drive next to Restore to and click Restore
- Once the backup has finished restoring, restart your Mac again.
Recover files from disk image
If you have a previously created disk image and need to restore files from it, try the following algorithm:
- Connect the external drive if the disc image is written on it. If it's stored directly on your device, find the disk image in storage. It can be a file with the extension .dmg or .iso
- Double-click it to have macOS create a virtual drive on your desktop or Finder
- Select and copy the files you need to the repository
- Close the virtual disk (click Eject)
- Check whether the documents and folders you need are saved.
You can also use the familiar Disk Drill utility we mentioned above to easily and quickly recover files from a disk image. If you haven't installed this tool yet, you'll have to start the process from this very step. If the app is already installed, open it and do the following:
- Find disk image in Disk Drill
- Select the Restore option next to the disk image you need
- Select your disk image again and scan it
- After the scan is complete, the utility will provide you with a complete list of files stored in the disk image that can be recovered. Select all or only the one you need
- Select the Recover option and specify the location to save this data
- Check that all files open as they should when the recovery process is complete.
How to boot your clone on another Mac
When you already have a ready clone Mac hard drive bootable version from the previous device that you used and you want to transfer this data to another Mac, you will need the drive where you saved the cloned version of the drive.
- Connect the external drive on which the disk clone is located
- Turn on the new Mac you want to boot from the clone. If the device was turned on before this, restart it (use the Option key for this)
- Select the external boot drive using the arrows
- Press Return to download files from the selected clone external hard drive Mac.
Bonus tip: How to keep your Mac clean?
Have you noticed that many files were redundant while you were doing a clone or backup? It happens when you actively use your computer for work or study: documents with similar names are created, files from the same subject are in different folders, etc.
