6. Select your MacBook from the list of devices. If you don’t see “All Devices,” it’s possible that you’ve already selected a device. In that case, click on the device’s name to proceed.
7. Once you’ve selected your MacBook, a window will appear with several options. Look for the “Lost Mode” or “Lock” option and click on it.
8. Follow the onscreen instructions to enter a phone number where you can be reached. This number will be displayed on the locked screen of your MacBook, so make sure it’s a number you have access to.

It’s important to note that Lost Mode or locking your MacBook will prevent anyone else from accessing your personal information and using your device.

If your MacBook is lost or stolen, it’s recommended to also report the incident to local law enforcement and provide them with any relevant information.

Remember to keep your Apple ID and password secure, as they are essential for using Find My iPhone and protecting your devices. Additionally, it’s a good idea to regularly back up your MacBook to ensure you have a copy of your important data in case of loss or theft.
