Time Machine is the built-in backup feature of your Mac. With this utility, you can make a backup of all your files, including apps, music, photos, email, documents, and system files to an external storage device. While the versatile file backup software - EaseUS Todo Backup provides you with more flexible backup solutions. There are some advantages of the third-party backup tool over Time Machine:

- Selectively back up the content on your Mac - With Time Machine, you have to make a backup of all the supported content
- Save more space on the target device - You can compress the backup to free up space on your disk.
Based on these features, I recommend you choose EaseUS Todo Backup for Mac as your backup option, which is easier and more flexible. If you prefer Time Machine, jump to the corresponding guide here.

Step 3: Click 'File+' to choose the files you'd like to backup. Click the Start button to begin backing up the selected files on your Mac to another drive or an external storage device.
With simple three steps, you can back up your important files on your Mac elsewhere and eliminate your worries of losing the data while resetting your MacBook or iMac.
Option 2: Back Up the Mac with Time Machine
Step 1: Connect a usable external storage device to your Mac.
Step 2: A window will pop up asking you how to use the drive. Select 'Use as Backup Disk'. If the window doesn't appear, go to Apple menu > System Preferences, then click Time Machine. Click Select Backup Disk and choose your external drive. (If the external hard drive shows up as 'Read Only' on your Mac or isn't formatted as required by Time Machine, you will need to reformat the disk.)
Step 3: Then Time Machine will back up your Mac automatically. Generally speaking, the first backup will take a long time. if Time Machine is stuck on preparing backup, check the fixed from the linked page.
