Back Up Your Data Before Erasing

Before you erase everything on your MacBook Air 2015, it’s crucial to back up your essential data. This step ensures that you don’t lose any important files. Here are some popular backup methods:

  • Time Machine: Apple’s built-in backup solution, Time Machine, offers a comprehensive way to back up your entire system. You can use an external hard drive or a network drive for this purpose.
  • Cloud Storage: Services like iCloud, Dropbox, or Google Drive allow you to store your files online, providing easy access from any device.
  • External Hard Drive: Copy your important files onto an external hard drive for safekeeping.

Method 1: Erasing Everything Using Disk Utility

Disk Utility is a built-in macOS tool that allows you to erase your entire hard drive. This method is the most secure way to erase everything on your MacBook Air 2015.

6. Erase the disk: Click on the “Erase” button to start the erasing process. This may take some time depending on the size of your hard drive.
7. Restart your Mac: Once the erasing process is complete, restart your MacBook Air 2015.

Method 2: Reinstall macOS
