To avoid data loss due to factory resetting your Mac, you can make a backup of your MacBook Pro, MacBook Air, iMac, or other Macs to an external hard drive with Time Machine or EaseUS file backup software for Mac.
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:
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.
Option 1: Back Up the Mac with EaseUS Todo Backup
Step 1: Connect an external drive with enough space (larger than the files you'd like to back up) to your Mac, launch EaseUS Todo Backup. Click the plus icon in the bottom-left corner to add a new project. Enter the name of the project and click 'OK'.
Step 2: Set up the backup destination and other backup settings. After that, click 'OK'.
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.
After choosing one of the methods above to back up your Mac, now you can start resetting your MacBook Pro, MacBook Air, iMac, or other Macs.

These options include restoring your OS from the Mac App Store, restoring it through macOS Recovery, restoring it via Internet Recovery Mode, and lastly, hooking up your machine to an external drive with a bootable version of your Mac OS.
Restore from Mac App Store
To restore from the Mac App Store:
1. Click on the Apple icon in the upper left corner of your screen.
2. Open the App Store. 3. Click on the Purchased tab in the Mac App Store window. 4. Look for your operating system from the list of purchased apps. 5. Click Download (you won’t be charged for reinstalling apps). 6. Click Continue to confirm that you want to install software that is already on your computer. 7. After the OS has been downloaded, click Install. 8. Wait for the installation to finish.
Start up from macOS Recovery
If you encountered issues downloading the Mac OS from the App Store, you can restore your operating system through macOS Recovery. This will allow you to choose which versions of macOS you want to install on your Mac.*
When initializing macOS Recovery, the following key combinations will allow you to install different macOS versions:
● Command-R restores the latest macOS that was installed on your Mac without upgrading to a later version.
● Option-Command-R upgrades to the latest macOS that is compatible with your Mac. ● Shift-Option-Command-R restores the macOS that came with your Mac or the version closest to it that is still available.
To initiate the restoration via the macOS Recovery
1. Start or restart your Mac.
2. Hold down any of the key combinations presented above. 3. Release the keys once you see the Apple logo or a spinning color wheel. 4. Wait for the macOS Utilities window to appear. 5. Continue to the next section and choose whether to erase your startup disk or begin reinstalling macOS.
Erase Startup Disk or Reinstall OS?
Erasing your startup disk prior to restoring your Mac OS is up to you, however, you might want to do this if:
1. Your computer is having an issue that Disk Utility can’t repair.
2. The macOS installer says that it can’t install on your computer or volume. 3. Your startup disk can’t be used to start your computer (this is likely to happen if you try to install an older macOS on top of a newer macOS). REMEMBER, ONLY DO THIS IF YOU HAVE BACKED UP YOUR HARD DRIVE FIRST!
If you need to erase your startup disk,
1. Select Disk Utility from the utilities window of macOS Recovery.
2. Click Continue. 3. Select your startup disk in the sidebar of Disk Utility. 4. Make sure you select the disk name and not the volume name under it. 5. Click the Erase button or tab. 6. If you don’t see an erase button or tab, select the volume name under the disk name, then look again. 7. Complete these fields: Name: Enter a name for your disk, such as “Macintosh HD”. Format: Choose Mac OS Extended (Journaled). Scheme (if available): Choose GUID Partition Map. 8. Click Erase to begin erasing your disk. 9. Once you’re done, quit Disk Utility to return to the utilities window. 10. You’re now ready to restore your macOS.
Restore your macOS
If you’re done erasing your startup disk or you think it’s not necessary, you may proceed with restoring your macOS.**
1. Choose Reinstall macOS (or Reinstall OS X) from the utilities window.
2. Click Continue, then follow the onscreen instructions. 3. Select a startup disk. 4. Click Install. 5. Provide your Apple ID to verify eligibility to install macOS if asked. 6. Wait for the installation to finish. 7. After the installation is finished, your Mac will restart.
Notes:
* If you’re selling or giving away a Mac running on OS X El Capitan or earlier, use Option-Command-R to make sure that your Apple ID will not be associated with the installation.
**If you erased your disk before restoring your OS, or you’re creating a new startup disk, your Mac will direct you to a setup assistant after restarting. If you’re keeping your Mac, you can just use your own information to finish the setup. If you’re selling or giving it away, press Command-Q to quit the setup assistant and finish the process.
Restoring Via Internet Recovery Mode
Sometimes, restoring your Mac OS via Recovery may not be possible – a damaged recovery partition being one of the possible reasons why. This is when Internet Recovery comes in handy.
Available on newer versions of Mac, the Internet Recovery mode is the internet-based counterpart of Recovery mode and works by downloading recovery tools from Apple’s servers into your Mac. Internet Recovery Mode, however, only allows you to restore the OS that came preinstalled on your Mac when you purchased it as opposed to Recovery Mode which allows you to restore the latest version of your OS.
If both of your Mac’s startup volume and its recovery partition are damaged or no longer work, the computer will automatically enter Internet Recovery Mode.
To start Internet Recovery Mode,
1. Go to the Apple menu.
2. Click Restart or power on your Mac. 3. Hold down the Command – Option – R keys immediately after your Mac starts. 4. Release the keys when the globe appears on the screen. 5. Wait for the Wi-fi menu to appear. 6. When the Wi-Fi menu appears, choose a Wi-fi network to connect to. 7. Once you’re connected to the internet, your Mac will download a recovery system image from Apple’s servers and use it to start the recovery process (note that this can take anywhere between a few minutes to a couple of hours). 8. Wait for the Utilities window to appear. 9. Click Reinstall OS.
Please note that you can only restore your Mac OS on a Wi-fi or Ethernet connection using WPA/WPA2 authentication protocols. If you’re connected to a network using either WEP, WPA-Enterprise, PPPoE protocols or any proxies, you will need to change the network settings to the required configuration first before the recovery process can continue and make sure that it stays that way until the installation is complete.
If for one, reason or another, the Internet Recovery Mode didn’t work as well, you can also restore your Mac OS by using an external drive with a bootable copy of your Mac OS.
Restore Your Mac OS via External Drive (see subject below for instructions on installing macOS on an external drive)
If you install the Mac operating system on an external hard drive, thumb drive, or other storage device, you can use it to restore your OS instead of going through the other three options.

To confirm:
1. Connect your external storage device to your Mac.
2. Choose Apple menu. 3. Click About This Mac. 4. Click the System Report button.
Alternatively, you can also:

If you’re using third-party external devices, your Mac may have some trouble detecting it. Because of security concerns, some of these devices use Option ROM firmware that Mac computers with updated software don’t automatically load.
To fix this, just press Option-Shift-Command-Period at the Startup Manager window. Do this each time you want to start from the external device or from a startup disk connected to it.
If you don’t want to do this and you’re using an older Mac model (2015 and before), you can can disable this security feature and allow your Mac to load Option ROM firmware. However, beware that doing this may make your Mac vulnerable to unauthorized access.
To disable this feature,
1. Open the Terminal app in the Utilities folder of your Applications folder.
2. Type sudo nvram enable-legacy-orom-behavior=1, then press Return. 3. To undo this command, enter sudo nvram -d enable-legacy-orom-behavior.
Notes:
1. The amount of time that it will take to start your computer and complete the installation process will largely depend on your external device’s processing capabilities.
2. Should you wish to use an external USB drive as a startup disk, please remember that the drive must have Mac OS X Tiger v10.4.5 or later installed, and your Mac must have an Intel processor.
3. If your Mac is using OS X Lion v10.7.3 or later, you can use Startup Manager to start from your Time Machine backup disk. You can find your Time Machine backup under the name ”EFI Boot.”
