Mac Product Key Finder. Devices scan
Mac Product Key Finder will show you your Mac OS serial number, serial numbers for your iPods, iPhones and iPads which you have connected
with iTunes before.
This can be very useful in case you'll lost or somebody stole your expensive devices to report these numbers to police.
This feature works in both Freeware and Professional versions. Pro version however, will show you a bit more info, such as IMEI.
