September 17th 2018 - iOS 12

Following are links to the latest firmware for the most recent Apple devices, and instructions on where they need to be stored on a Mac for them to be recognised by iTunes or Apple Configurator

Apple Configurator 2.X Users
The code before ‘group.com.apple.configurator’ may change depending on your local configuration.

~/Library/iTunes/Apple TV Software Updates
~/Library/iTunes/iPad Software Updates
~/Library/iTunes/iPod Software Updates
~/Library/iTunes/iPhone Software Updates
