MacBook
- Back up with Time Machine to an external drive, or make sure your files are in iCloud.
- Sign out of your Apple Account: Apple menu, System Settings, click your name, then Sign Out. This also turns off Find My and Activation Lock.
- On recent versions of macOS, erase it with System Settings, General, Transfer or Reset, then Erase All Content and Settings.
To check Activation Lock is off, open System Information: under Hardware, “Activation Lock Status” should say Disabled. If the MacBook will not start, sign in at iCloud.com, open Find Devices, choose the MacBook and remove it from your account.
Windows laptop or desktop PC
- Back up your files to an external drive or OneDrive.
- Sign out of apps and browsers you are signed in to.
- Reset it: Settings, System, Recovery, Reset this PC, then Remove everything. Under “Change settings”, turn on data cleaning, and if the PC has more than one drive, choose to delete files from all drives.
- Afterwards, remove the device from your Microsoft account’s device list online.
If the laptop has a BIOS or firmware password, remove it before handover. If BitLocker is on, the reset takes care of it: please do not send us your recovery key.
iPhone
- Back up to iCloud or to a computer.
- If you have an Apple Watch, unpair it first.
- Sign out: Settings, tap your name, then Sign Out. This turns off Find My and Activation Lock.
- Erase it: Settings, General, Transfer or Reset iPhone, then Erase All Content and Settings.
- Take out the SIM card. If you use an eSIM, check with your network first.
If the iPhone will not turn on, sign in at iCloud.com, open Find Devices and remove the iPhone from your account.
Android phone
- Back up your photos, contacts and messages, for example with your Google account’s backup.
- Remove your Google account from the phone (in Settings, under Accounts or Passwords and accounts). On a Samsung phone, remove your Samsung account too. Removing accounts first stops the phone asking for your account after a reset.
- Factory reset it from Settings. The menu names vary by make: look under System, Reset options, or General management, Reset.
- Take out the SIM card and any memory card.
Work and school devices
Devices enrolled in Apple Business Manager, Microsoft Intune or similar tools can only be released by the organisation. Ask your IT team to remove the device from management, and make sure you are authorised to sell it. A reset on its own is not enough.
