Disconnecting the dGPU in a late 2011 MacBook Pro —third way
Update 2017.12.12-14.20 EET: whether or not I use the AMDGPUWakeHandler and whether I sleep or hibernate I can’t wake up of the hibernation/sleep. Depending on if I have AMDGPUWakeHandler on or off I get different outputs, but none of those end in a successful wakeup.
