Inferno (utility)



Inferno is a diagnostic utility used in Apple internal firmwares. Its functionality is similiar, if not the same, to the BurnIn utility. It runs a set of hardware and software checks predefined by PList files. It can shut itself down if device reaches critical temperature level. It can also be accessed in any firmware by passing the boot argument "inferno" to the device. Because development iBoots pass boot arguments to the kernel (unlike production variants), this can be done on any prototype device. The following are pictures and documentation of prototype devices running known Inferno builds.
