Wiping data before a computer leaves the business

Why "I deleted everything" is not a wipe, how to wipe Mac and Windows properly, dead machines, and records. With a checklist.

Wiping data before a computer leaves the business

"Don't worry, I deleted everything." Usually that means a folder dragged to the bin. A computer leaving the business takes email, client files, saved passwords and accounting documents with it. Here is how to wipe it properly.

Why "deleted" is not wiped

  • Deleting files and emptying the bin only marks the space as free; most files can be recovered with free tools.
  • A quick format does the same for the whole drive.
  • Removing the employee's user account leaves temporary files, local backups and browser data behind.

What does work

  • Encryption from day one: BitLocker on Windows, FileVault on Mac.
  • A full reset: Erase All Content and Settings on Apple Silicon Macs; on Windows, Reset this PC with remove everything and clean the drive.
  • Professional wiping with records: a dedicated tool that wipes the whole drive and documents each machine by serial number.
  • Dead machines: the data is still there. Remove the drive and destroy it, with documentation.

Disconnect it from your accounts

  1. Turn off Apple ID and Find My, or the Mac stays activation-locked.
  2. Sign out of Microsoft and Microsoft 365 and release the licence.
  3. Remove it from MDM (Intune, Jamf, Apple Business Manager).
  4. Sign out of browser sync and password managers.

Why records matter

Businesses in Israel must protect the personal data of clients and employees, including when a computer leaves. A list of which machines were wiped, when, how and by serial number shows you did what was needed. This is not legal advice.
