Hey everyone, Long time reader, first time posting. I just installed beta 6 on my 2013 Mac Pro. Is anyone else experiencing issues with multi-monitors? I have three of the same Dell U2515h monitors, but since beta 6 update, only 1 is working at a time. All the other betas were fine. I have tried the "detect displays" hidden button (hold down option in the display preferences) in display preferences, but this doesn't do anything either.
