Question: Black screen MBP 2012 after High Sierra install
So, having gone through the install process I cannot see any video at all on the internal display. However, attaching an external Dell display does show all the desktop and it works fine. Going into the Preference->Displays shows only the external Dell device. Pressing the option key brings up the detect displays button which has no action when clicked (I would expect to see the internal display mentioned). Looking in the logs I see entries about mirroring only running for 0 seconds.
Attempting safe mode or recovery or single user never activate the internal display. This was workigwhen I started this sage BTW. I've tried resetting SMC and NVRAM several times to ne effect.
Just wondering if there is something missing I should try please?
MacBook Pro, Mac OS X (10.0.x)
