I read this on the fallout wiki ''If the player has completed Still in the Dark, stayed on good terms with the Brotherhood, and McNamara remains Elder, a truce can be signed between the Brotherhood and the NCR'' but now after finishing 'still in the dark' McNamara won't speak to me, he just says that he is busy ! what do i do!!?!?!

leave the bunker and wait 72 hours or so, it should work

Thanks ! it worked :thumbsup:

You don't even have to wait 72 hours. I left the bunker on another errand and came back, all within a few hours, and I could converse further with him. As long as you completely (i.e. go through the door back to the wastes) leave the bunker and go back in the additional dialogue will show up.

I sided with Night Hardin and cannot get him start his quest, he tells me to come back later, I waited 4 days and its still not triggered.
