This guide will go through the process of cloning your existing software, OS, and data to a new hard drive.

(SuperDuper is now compatible with Big Sur & Monterey.)

***NOTE:*** With the introduction of macOS Catalina, certain steps in this guide are out of date.

***''IMPORTANT: Cloning the hard drive is not recommended''*** ''if you have a Mac that uses a  recovery partition (MacOS 10.7 - present) or internet recovery (2011 - present). Instead, to move your data to a new drive, first [guide|119046|create a backup of your existing drive|new_window=true]. Then, either use [guide|119499|internet recovery|new_window=true] or [guide|66371|create a bootable external drive|new_window=true] so you’ll be ready to install macOS onto your new drive and migrate your data afterward.''

If you are happy with your existing operating system installation and would simply like to upgrade your hard drive capacity, you can clone your existing hard drive to your new drive.

To clone your hard drive, we recommend a program called [link|http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html|SuperDuper!], by Shirt Pocket Software.

The following instructions assume that you’ll be using SuperDuper! and the 2.5" hard drive enclosure to clone onto a new 2.5" drive. If you are using a different setup, your installation process may be somewhat different.
