Needy Posted November 6, 2016 Share Posted November 6, 2016 I followed this guide: http://www.insanelymac.com/forum/topic/313305-macos-sierra-usb-installer/Hello there, The error in the pictures states that the SMC returned an invalid key, which triggered the Don Steal Mac OS kext. Is there a fakesmc kext in your system? If no, 1. download one from a trusted website, or search on this forum for fakesmc. If there's a fakesmc kext, delete it and do (1), (rebuild kernel cache if the fakesmc was installed in the System/Library/Extensions previously). Afterwards, if the boot loader is clover, make sure that there is no fakesmc kext in the EFI/Clover/Kexts and copy the kext from (1) to the other or "macOS version" folder, otherwise search for instructions on how to use a third party kext with the specific boot loader.
