Did you leave your iPhone somewhere? Did your laptop get stolen? Has that mischievous 5-year-old hidden your iPad again?
Now you can check into iCloud.com to see exactly where your Mac, iPhone, or iPad is. You can even make it beep loudly for 2 minutes, so you can figure out which couch cushion it’s under, or which jacket pocket you left it in. If the missing item is an iPad or an iPhone, you can make it beep even if the ringer switch is off, and even if the device is asleep. You can also make a message pop up on the screen; if you actually left the thing in a taxi or on some restaurant table, you can use this feature to plead for its return. The bottom line: If you ever lose your Apple gear, you have a fighting chance at getting it back.
(That’s if it’s online, and if you turned on Find My Mac in the iCloud panel of System Preferences.)
