Step 1: Clean up your Mac
So listen, you’re definitely going to want to do a backup of your Mac in case something goes wrong. To make that process easier, you should first clean up your Mac. It may sound like a daunting task, however, there are tools that can help you out, like CleanMyMac.

Step 2: Back up your Mac
Backing up is just good practice. If something goes wrong, you don’t want to be left stranded without a backup of your Mac. Now, if you don’t wish to back up your Mac, you can proceed to step three. But remember, if you don’t have a backup and something goes wrong, you won’t be able to recover or restore anything from your current Mac. With that said, here are the steps for backing up your Mac:
- Go to your Applications folder and click Time Machine.
- Click on “Select Disk.”
- Select the external drive you wish to save your backup. An Apple Time Capsule is the ideal place to save it to. If you don’t have one, choose a different external drive.
- Click “On” to turn Time Machine on; the button is located on the left-hand side of the menu.
- To the right, below the name of the storage device, you’ll find, “Oldest backup,” “Latest backup,” and “Next backup.” Your backup should start within the next 5 minutes.
