PurpleRabbit

PurpleRabbit is an internal macOS app which can restore devices much like PurpleRestore and iOS Restore Tool, and can also print labels. This app seems to be to be used in factories, as the software uses files and libraries that are only found in factory machines. The app also has a label maker window, which allows workers to print out labels which have device information on them. These labels are then placed onto prototype devices and are used for identification, as there are usually many different type of prototypes of any given device that all perform differently or contain different features. The best example of this would be prototype iPhone 12 models. During the prototyping phase, there were many different models which had different capabilities and features. Some models supported 120Hz refresh rates while some didn't, etc. These models would all have a different model number depending on their features, therefore making it necessary to print out labels containing each prototype's model number, so that none of them get mixed up. Within the PurpleRabbit app, there is also a menu bar option that allows engineers to file a Radar.

By default the app will not launch correctly, and instead will throw an error saying "Failed to load Jobs.plist", which is actually nonexistent within the app's Application Support directory. As of version "61.40.4~301", this is no longer the case. If PurpleRabbit doesn't detect a Jobs.plist, it creates a blank one and continues to run.
