Erase Everything on Your Mac

To erase or format everything on your macOS, you must follow the two guidelines listed below.

1. Backup Your Important Data Using Time Machine

Your applications, music, papers, images, emails, and system files are all backed up by Time Machine and any other computer data. If it is turned on, it will back up the files on your Mac hourly, daily, or weekly, depending on your choice.

Every hour, Time Machine will scan your computer to look for files that have been added, modified, or deleted to create fresh backups of your Mac. The program maintains a daily backup for the most recent thirty days of data.

Additionally, it will maintain weekly backups so long as there is space left on the storage device. The oldest backups will be removed and erased when there is no more space available on the storage device.

Step 1. You may add an external hard disk to your Mac by connecting it.

Step 2. After that, choose the Apple symbol located in the menu bar.

Step 3. Next, choose the System Preferences menu option.
