Why Wipe Your MacBook's Disk?

For safety and protection of your personal information, you must wipe your MacBook's disk. It's hazardous to leave your data on the disk when you get a new MacBook, sell the old one, or give it to someone else. Without proper wiping, people who aren't supposed to have access could see private papers, financial records, login information, and browsing history.

By safely wiping your MacBook's disk, you lower the chance of identity theft, scams, and people accessing your personal information without your permission. In addition, wiping the disk ensures that you follow data protection laws and maintain high standards for data privacy.

Make A Backup Before Wiping MacBook's Disk

It is essential to back up any critical data you want to keep before you start the disk wipe process. You can ensure your files are safe somewhere else by using Apple's Time Machine or a cloud storage service like iCloud or Dropbox.

Here, we introduce another way to back up your MacBook - make a full bootable clone with Disk Clone app.

Step 1. Download and install the reliable Mac disk clone app - DoYourClone for Mac.

Step 2. Connect an external hard drive to your MacBook, then open DoYourClone for Mac, choose Clone OS mode. This mode will clone all data from the MacBook to the external hard drive, and make a bootable clone backup.

Steps to Wipe MacBook Disk

1. Disconnect iCloud and Other Accounts

It is very important to disconnect the MacBook from iCloud and any other accounts. To do so, go to System Preferences/System Settings > Apple ID and sign out of iCloud, iTunes, the App Store, and any other linked services.

2. Deauthorize Apps

If you bought anything from the Mac App Store or iTunes, ensure these sites don't have access to your MacBook. This step keeps your purchased material from having licensing problems on other devices.

3. Turn off Find My

By turning off "Find My," you can be sure your MacBook will not be linked to your Apple ID after the wipe. Please turn it off by going to System Preferences/System Settings > iCloud > Find My.
