Thus, we have researched various ways that can help you to restore MacOS without losing your data or files. Now, the way to do so might be with the help of a backup or by recovering the data later, but in the end, you will have your MacOS restored without losing data.
Part 1. Try to Restore Mac with The Help of Time Machine Backup
Now, as you have already Restored MacOS to its default and are left with nothing but empty drives and lost files, all you can do is to restore Mac with your old backup files. There are several ways to restore Mac, but let’s suppose that you played safe and already took a backup of your Mac with the help of Time Machine. Now, you can restore Mac with the old data by restoring a single backup file from the Time Machine. Let’s see, how?
Follow the Steps to Restore Mac from Time Machine Backup:
Step 1 To restore Mac with Time Machine, you first need to restart your Mac, you can do so by going to “Apple Menu” on top of your home screen and choosing the “Restart” button. Now, wait until your Mac restarts.
Step 2 Once the Mac restarts and is in the early process of rendering the OS, you need to press and hold the “Command” and “R” keys together, hold them for a while until the Apple logo appears, followed by “MacOS Utilities Menu”. If the MacOS Utilities Menu doesn’t appear, you need to try again, try to press the command keys in the early stage of Reboot.
Step 3 Once you have the MacOS Utilities Menu in front of you, you’ll see that the very first option is the “Restore from Time Machine Backup” option, you need to click on that very first option among the various options to restore Mac with the help of Time Machine Backup, and then click “Continue” if asked.
Step 4 You will be transferred to “Restore Your System Page”, you need to click on “Continue” once again.

Thus, it is advisable to take a backup of your Mac on Time Machine before restoring your Mac, because Time Machine is the only integrated tool that you can fully rely on, and it’s the only to provide you with a full restoring feature once you restore MacOS.
Part 2. Try to Restore Mac with the Help of iCloud Backup
If not from the Time Machine, you can restore Mac with the help of iCloud Backup as well. The only thing is that iCloud doesn’t provide you with the full restore feature as the Time Machine. You will be required to go to the iClouds drive and sync the data to your Mac to get it back. The only condition is that you took the backup of your Mac or synced your data to iClouds before restoring MacOS, if yes, then this should be easy.

Step 2 Once you are into your iClouds account, you will see a “Gear” icon that represents iCloud Settings. Click on that “Gear Icon”, it will take you to a new settings windows, in that new window, keep scrolling down until you see “Advanced” section. Under that Advanced section, you will see various restore options i.e. Restore Files, Restore Contacts, Restore Bookmarks etc. Click on “Restore Files”.
