Hi, So I installed Yosemite today and already regret it. Installed fine, but for whatever reason now, my 2012 Mac Mini which was working fine on Mavericks at 3440x1440 at 50hz on my LG 34 inch 34UM95 no longer picks it up on the newer version. Now I am stuck at 2560x1080 at 60hz with no option to make any changes. Even tried a few custom apps and no dice. This kind of stinks obviously as it was working just fine previously, but this upgrade has broken my resolution on my monitor. I'm sure Apple will say the Mini only supports 2560x180, but it worked fine before. I was hoping they would not remove features and leave the HD 4000 drivers alone. Thought I would FYI everyone on this. Completely irritated.
