Wipe your iMac before selling: step-by-step guide

Are you planning to trade in or sell your iMac? Then it’s essential to erase all your personal data before handing over the device. Not only to protect your privacy, but also to give the new owner a clean start. In this step-by-step guide, we explain exactly how to wipe your iMac, whether you’re using macOS Ventura, Monterey or an older version.

Why should you wipe your iMac before selling?

An iMac usually contains personal documents, photos, emails and accounts. Erasing your computer prevents this data from falling into the wrong hands. At Verkopen.nl, we always recommend securely wiping your iMac before selling it. This way you can sell it with peace of mind.

Step 1: Back up your data

Before erasing everything, it’s smart to create a backup. You can use Time Machine or manually copy files to an external hard drive or cloud storage (such as iCloud, Google Drive or Dropbox). This prevents losing important data.

Step 2: Sign out of your accounts

Make sure to log out of the following:

• iCloud (via System Settings > Apple ID > Sign Out)
• iTunes (via the menu bar: Account > Authorisations > Deauthorise This Computer)
• iMessage (via Messages > Settings > iMessage > Sign Out)

This ensures your iMac is no longer linked to your Apple ID.
