Apple Configurator 2 is a great tool. But you need to debug things from time to time. This might mean that a profile is misconfigured and not installing, or that a device can’t perform a task you are sending it to be performed. This is about the time that you need to enable some debug logs. To do so, quit Apple Configurator and then write a string of ALL into the ACULogLevel key in ~/Library/Containers/com.apple.configurator.ui/Data/Library/Preferences/com.apple.configurator.ui.plist:
defaults write ~/Library/Containers/com.apple.configurator.ui/Data/Library/Preferences/com.apple.configurator.ui.plist ACULogLevel -string ALL
To disable, quit Apple Configurator and then delete that ACULogLevel key:
defaults delete ~/Library/Containers/com.apple.configurator.ui/Data/Library/Preferences/com.apple.configurator.ui.plist ACULogLevel
