iPod sales have almost topped 10 million world wide. They are also becoming a popular device for suspects to store information other then just MP3s on thanks to their ability to be used as a mass storage device. Every time an iPod is attached to a Mac, the serial number of the iPod is recorded by the system. Being able to prove a specific iPod was connected to a suspect machine can be beneficial to an investigation.
You can use the MacForensicsLab Analyze function to explore the following file: ~/Library/Preferences/com.apple.iPod.plist This file shows the serial number, firmware, and model of the last Apple iPod connected to the suspect drive. This will allow the investigator to track down the iPod used and see if there may be further evidence contained on it.
