My computer always gets stuck, and I want to upgrade my Mac's hard drive to a big new SSD. How can I clone my system to the new SSD?"

Here are two ways to solve this similar problem.

Method 1: Backup and Restore the EI Capitan to the New SSD

When you want to clone your Mac system or hard disk to other hard disks, the tools that come with the system can also help you achieve this purpose. Cloning the hard drive to others in Mac EI Capitan is called "Recovery" (recovering one hard drive to another).

The following are the specific operation steps:

Step 1: Connect the prepared external hard drive to your Mac computer. Then start the computer. Keep pressing [Command + R] during the startup process. This will enter the Mac recovery menu interface.

You can use the clone disk as a bootable startup disk on any compatible Mac. You also can use the backup to restore macOS or data in macOS Recovery mode.

The disk cloned by DMclone can also be used as a backup disk. When you need to restore the backup data, you can use the disk you backed up to handle this matter. (Note: This restore is for all data on the backup disk and cannot be restored individually)
