Welcome to this guide on how to erase everything on Mac! If you’re planning to sell or give away your Mac, or just want to fresh start, erasing everything on your Mac is essential. But hold on, before you start wiping out your data, make sure to back up everything you need. This article will guide you through the steps on how to erase everything on Mac safely and securely.
Step 1: Sign Out of iCloud
Before erasing everything on your Mac, you need to sign out of iCloud. To do this, go to Apple Menu > System Preferences > iCloud > Sign Out. Make sure to uncheck the box that says “Keep a copy of my iCloud data on this Mac”.
Step 2: Deauthorize iTunes

Step 3: Sign Out of iMessage and FaceTime
If you use iMessage and FaceTime, sign out from these services. Open Messages, click Messages > Preferences > Accounts, select iMessage account, and click Sign Out. For FaceTime, click FaceTime > Preferences > Settings > Sign Out.
Step 4: Create a Bootable USB Drive with macOS
You need to create a bootable USB drive with macOS before erasing everything on your Mac. Download macOS from the App Store, then follow the instructions on the app to create a bootable USB drive.
Step 5: Restart Your Mac in Recovery Mode
To erase everything on Mac, restart your Mac in Recovery Mode. Press and hold Command + R while your Mac is starting up.
Step 6: Use Disk Utility to Erase Everything
In the Recovery Mode, go to Disk Utility and click Continue. Select your Mac’s startup disk, click Erase, and type in the name and format of the new disk. Click Erase, and wait for the process to finish.
Step 7: Reinstall macOS
After erasing everything on your Mac, quit Disk Utility and select Reinstall macOS from the macOS Utilities window. Follow the instructions on the screen to reinstall macOS.

2) How do I back up my data before erasing everything on my Mac?
You can back up your data using the Time Machine feature on your Mac. This allows you to create a complete backup of your Mac’s hard drive, including all of your files and settings. Alternatively, you can manually transfer your files to an external hard drive or cloud storage service.
3) Can I selectively erase certain files on my Mac?
Yes, you can selectively erase certain files on your Mac by manually deleting them or using a specialized tool such as CleanMyMac. However, if you want to completely erase all data from your Mac, you need to use a different method.
4) How do I erase everything on my Mac?

5) What is the difference between erasing and formatting a hard drive?
Erasing a hard drive removes all of the data on the drive, but does not change the underlying structure of the drive. Formatting a hard drive, on the other hand, completely wipes the drive and creates a new file system, such as HFS+ or APFS.

The time it takes to erase everything on a Mac depends on the size of the hard drive and the method used to erase it. A typical hard drive can take several hours to erase completely.
7) Can I speed up the erasing process?
You can speed up the erasing process by using a faster method, such as a zero-fill or multi-pass erase. However, these methods are more time-consuming, so it’s a trade-off between speed and security.
8) Is it possible to recover erased data from a Mac?
It is possible to recover erased data from a Mac, but only if it has not been overwritten by new data. That’s why it’s important to use a secure erase method that completely wipes the data.
9) Can I erase everything on a Mac remotely?
Yes, you can erase everything on a Mac remotely using the “Find My” feature on your iCloud account. This allows you to remotely erase the data on a lost or stolen Mac.
10) How can I tell if everything has been erased from my Mac?
You can tell if everything has been erased from your Mac by trying to access any of your old files or settings. If everything has been erased, there should be no trace of your old data on the computer.
11) Do I need to reinstall the operating system after erasing everything on my Mac?
Yes, you need to reinstall the operating system after erasing everything on your Mac. This is because the operating system is also erased during the process.
12) What happens if something goes wrong during the erasing process?
If something goes wrong during the erasing process, you may need to take your Mac to a professional repair service. However, if you have backed up your data beforehand, you should be able to restore it to a new Mac.
13) Can erasing everything on a Mac harm the computer?
No, erasing everything on a Mac should not harm the computer itself. However, it is always important to follow the correct procedures and backup your data before undertaking such a drastic step.
