I heard that it is possible to get alerted if I leave one of my Apple devices somewhere. Is this true?
Yes, and these are known as Separation Alerts. Launch the Find My app on your iPad (or one of your other devices) and tap on ‘Devices’ to see all of the Apple devices that are signed into the current iCloud account. Tap on one and, if your chosen device is compatible with Separation Alerts, you will see the ‘Notify When Left Behind’ option. Turn this on and then you can add exception locations, such
as your home, so you aren’t notified every time you leave your house without one of your Apple
devices. It can be handy in some situations.
